00:00:00Hey, welcome back to the Cycle World Podcast.

00:00:03Kevin Karon's with me. I'm Mark Hoyer.

00:00:07Our topic this week is,

00:00:09Kevin called it, how much better it could all be.

00:00:14I say, what's making the modern motorcycle so slow?

00:00:18Now it's fast, but also there is so much potential out there.

00:00:22What can we change to have 300 mile an hour motorcycles?

00:00:26You name it.

00:00:27So Kevin and I, mostly Kevin,

00:00:30Kevin went off and did some maths.

00:00:32I like to call it maths like the British

00:00:34because it makes it sound like there's more of it.

00:00:37Yeah.

00:00:37And there is a lot.

00:00:38And so maths is kind of an overwhelming

00:00:41but awesome way to describe it.

00:00:43So Kevin went off and did the maths

00:00:44and worked up a few things.

00:00:47And we'll let him release the clutch on the podcast.

00:00:52Okay.

00:00:53Get us moving.

00:00:54One of the obvious things that holds motorcycles back

00:00:59is that they are, in the language of the wind tunnel,

00:01:04aerodynamically dirty.

00:01:06Dirty.

00:01:07Horrible.

00:01:08I always go back.

00:01:10Caltech with the midget, they called it,

00:01:12the Harley XRTT.

00:01:14And they were doing wind tunnel testing in Caltech.

00:01:17And they put a motorcycle in there

00:01:19and they blew the air over it

00:01:21and they got their numbers.

00:01:23And then they put a flat piece of plywood

00:01:25with the same frontal area.

00:01:27In the tunnel.

00:01:28And it had, in the tunnel,

00:01:30just the plywood.

00:01:32And it had better aerodynamics than a motorcycle.

00:01:35Yes.

00:01:36It's crazy.

00:01:37It's so tragic.

00:01:39Yep.

00:01:39Well, here we have these MotoGP bikes,

00:01:46which are very powerful.

00:01:49People have started to go off the deep end now.

00:01:52The last claim I saw was 340 horsepower.

00:01:55And before that, it was 300.

00:01:56And to me, 275 looks pretty impressive

00:02:00because back in the days of the early 752 strokes,

00:02:06which was where I stepped on the moving belt,

00:02:11somewhere between 90 and 120 horsepower was,

00:02:16that was the revolution of 1972.

00:02:20So 275 horsepower is a bunch.

00:02:26And yet, the top speeds that have been seen

00:02:30are up to about 225 miles an hour.

00:02:35Oh, is that all?

00:02:36And so I worked through it to see what a ballpark figure

00:02:46for frontal area multiplied times aerodynamic coefficient,

00:02:53drag coefficient, C sub D.

00:02:58We all know what frontal area is.

00:03:00If you put your motorcycle in front of a white screen

00:03:03and had a pinpoint source of light miles and miles away,

00:03:07and you drew the outline of the motorcycle shadow

00:03:12and measured that area, that is frontal area.

00:03:15I did that in a long basement once with my 750.

00:03:21Anyway, frontal area multiplied times a figure of merit

00:03:27that tells us how much better the streamlining of the object

00:03:32we are interested in is than a piston

00:03:38of the same frontal area as the motorcycle,

00:03:41which pushes all the air ahead of it

00:03:44and doesn't let any flow around it.

00:03:46It just pushes it forward.

00:03:48In other words, all the air that it encounters

00:03:51is accelerated to the speed of the vehicle.

00:03:54So by rounding the edges, I think Volkswagen found

00:03:59that rounding the edges on their little Volkswagen van

00:04:04raised the top speed quite substantially

00:04:08from, what was it, 48 miles an hour or something.

00:04:12And then you see these people cutting the,

00:04:16used to see these people cutting the gutters off their cars

00:04:19because it just makes them take off, man.

00:04:21Rounding the corners is a great thing.

00:04:27But here are some sample drag coefficients, C sub D.

00:04:36A really good car might be somewhere in the 0.3s.

00:04:42A Zeppelin of the World War I era, 0.05.

00:04:49A fireplane, a piston engine fireplane of World War II, 0.14.

00:04:56And a motorcycle, 0.6.

00:05:03So it's right there with a bread truck.

00:05:07A big rectangular parallelepiped being shoved

00:05:10through the air by its engine.

00:05:13Now, what is streamlining?

00:05:15The aim of streamlining is not to share the vehicle's energy

00:05:20with anything else.

00:05:23So we want to push aside the air molecules,

00:05:28nitrogen and oxygen chiefly, that are in our way.

00:05:31Just push them to the side.

00:05:33Don't get them tumbling or whirling or forming vortices.

00:05:37And then as we pass, to let them gradually close behind us

00:05:42and resume their original positions, velocities, and directions.

00:05:48Now, clearly impossible.

00:05:51But the modern airplanes get some pretty good C sub Ds

00:06:03and they're able to go a tremendous distance.

00:06:07Their glide ratios are up around 17 or more.

00:06:11So if you're a mile high,

00:06:14you would intersect Mother Earth 17 miles farther along.

00:06:18But now look at the rules from 1958.

00:06:25They said no more dustbin fairings.

00:06:28They have bad gust response.

00:06:30They are crazy, veering, yaw-prone threats to navigation.

00:06:40So we'll have no more of that.

00:06:42Because it used to be that they would build

00:06:45these beautiful Craig Vetter-like enclosures

00:06:49for the motorcycle and the rider in the tucked-in position.

00:06:55Well, and way out in front of the front wheel.

00:06:57I mean, they were just really, I mean, they were long noses.

00:06:59They had long tails.

00:07:01They had a long tail section.

00:07:03Usually the tail was removed.

00:07:05They'd go out and practice.

00:07:08You want the tail off?

00:07:09Yeah, I think so.

00:07:10Yeah.

00:07:12But they were highly efficient,

00:07:14which is how 125s making 20 horsepower

00:07:17were able to get up to 125 miles an hour.

00:07:23So I thought to myself,

00:07:25I'll just do some calculations here

00:07:31and see what would happen

00:07:33if we could cut frontal area times C sub D in half.

00:07:42And I found that if our top speed is 220 originally,

00:07:47the new top speed would be 277 miles per hour.

00:07:51Now, that may be a little disappointing

00:07:54because we've cut the CDA in half.

00:08:01But the terrible fact is that aerodynamic drag,

00:08:06the force of drag increases as the square of velocity.

00:08:13And if we want the horsepower that is required

00:08:17to overcome that drag, we need another velocity term

00:08:20because horsepower is force times velocity.

00:08:24So then it becomes drag is proportional to,

00:08:31horsepower is proportional to speed cubed.

00:08:38So if we want to go twice as fast,

00:08:42it's going to take two times two times two

00:08:44or eight times more horsepower than we presently have,

00:08:49which is a tall order.

00:08:51Pretty tall order.

00:08:52I wanted to really quick,

00:08:53you were talking about the guys

00:08:55taking the tail section off for aero.

00:08:57Joe Petrolli in the 30s, I think it was,

00:09:01had a land speed knuckle, knucklehead,

00:09:05and they took it out and he was, you know,

00:09:07going for a record and he did set a record.

00:09:08It was in the 130s or something,

00:09:10but he set the record without the back of the bike on it

00:09:14because it was just like a little cap over the handlebars.

00:09:17And then these like fared in girder forks

00:09:21and then the tail section was really long

00:09:23and instability, putting that stuff behind him really,

00:09:27so they actually took the stuff off

00:09:29for him to set the record.

00:09:32Well, there was a thing about center of pressure, right?

00:09:34You know, we're moving the center of pressure

00:09:36and if it's not in the right spot, bad things happen.

00:09:39Not only that, but if you increase the sort of

00:09:42mass times lever arm of the rear caster,

00:09:47you can invite into your home, so to speak,

00:09:54the dreaded high-speed weave.

00:09:57And we don't, we don't want, we don't talk about that.

00:10:00We're good industry guys and we never mention weave.

00:10:03So if anyone asks you, you tell them.

00:10:09It's not a good, well, this is why Europeans load a tank bag.

00:10:13It's weight forward rather than having a,

00:10:18one of those hanging planters sticking up behind the passenger

00:10:23with all the bedrolls and tents and Coleman stoves

00:10:27and so forth, strapped to it.

00:10:29Yeah.

00:10:31Load forward.

00:10:33You got to work really hard if you're going to have

00:10:35all that stuff on the back of the bike.

00:10:37Very common to get a D-cell shimmy.

00:10:39If you just, if you just take random street bike

00:10:41and say, oh, we're going to put a top trunk on it.

00:10:44You put the trunk on it, D-cell shimmy.

00:10:47I test for that somewhat riskily, I suppose,

00:10:50but you just roll off and then you take your hands off

00:10:53because you have a natural tendency to damp the movement

00:10:57and at low, let's say, low magnitude, it's fine.

00:11:03If you just get a little bit, you take it off

00:11:04and it goes, and you're like, okay, none of that.

00:11:09You don't want it to get away from you.

00:11:10I will do up the snaps on my glove before departing

00:11:13rather than as I ride.

00:11:15I always love that Bates faring that they made,

00:11:17this great big Bates faring that had a trunk

00:11:19behind the headlight and in front of the windscreen.

00:11:23They had a big front trunk, and I'm like,

00:11:27well, don't put your bowling balls up there.

00:11:30No bowling balls.

00:11:31I think the best place for weight is down low

00:11:33and forward of the rider, in fact.

00:11:35So if you could put your saddlebags somewhere up there

00:11:39around the mass of the engine, you'd probably be best off.

00:11:41Yes.

00:11:42So what's wrong with motorcycles

00:11:44that they have such high drag coefficients?

00:11:46Well, the first thing is they don't look like a salmon or a trout

00:11:50because a salmon or a trout looks like it's designed

00:11:53to push the water aside and then put it back together again.

00:11:59Go, nature.

00:12:00I think it was Dennis Manning.

00:12:01Dennis Manning said that exact thing.

00:12:05He was like, when I went out,

00:12:07because Dennis Manning's a longtime land speeder,

00:12:10and he said that.

00:12:10He said, well, you know, when I started doing this,

00:12:14there were all kinds of different aero things going on,

00:12:17but I thought, well, you know,

00:12:18nature's been at this kind of a long time.

00:12:22And so we copied, you know, we started looking at salmon.

00:12:27You know, salmon swim upstream, and it's a lot of work.

00:12:30So we're going to get the most out of it.

00:12:33Got it.

00:12:35The thing with the motorcycle is that it makes no attempt

00:12:39to close its wake.

00:12:41Now, who cares about closing the wake?

00:12:43Look at the front of the thing.

00:12:44It's nice and round, and it's smooth.

00:12:47No, it's not, because the wheel is sticking out there.

00:12:53So I'm reading through a bunch of stuff in aero books,

00:12:56and it comes up with this gem.

00:13:00One of those 1950s B-47 jet bombers, four engines,

00:13:06is descending to land.

00:13:09And at the highest speed for which it is qualified

00:13:14to lower the gear, they lower the landing gear,

00:13:19and the drag doubles.

00:13:22They've just stuck a couple of wheels out of the fuselage,

00:13:25and one's out at the wingtips or somewhere.

00:13:28They haven't disturbed the whole thing to a tremendous extent,

00:13:33but the drag is doubled by sticking those turbulence-generating

00:13:37undercarriage legs out into the air.

00:13:41So a motorcycle has this disturbance-creating front wheel in the front.

00:13:50Oh, well, it's got a smooth fender on it.

00:13:53Come on.

00:13:56No.

00:13:57And, of course, the motorcycle does not have a long tail

00:14:02that puts the air back where it was comfortable before we arrived.

00:14:07And the way the tapered tail works to improve the coefficient of drag

00:14:16is as if the air is a big, slippery hand grasping a tapered bar of soap.

00:14:23You give it a squeeze, and patooey, it produces thrust.

00:14:29Well, Rich Oliver, famous 250 racer with so many championships,

00:14:34250 AMA, 250 two-stroke, 250 Grand Prix.

00:14:38He talked about a Daytona moving out of the saddle

00:14:44and arching his back until he felt a certain pressure,

00:14:50and for sure his leather stopped flapping,

00:14:53because if you see the guys go,

00:14:54and he would pick up RPM just by getting off the saddle.

00:14:58Now, that's great to talk about,

00:15:01but when you're getting mashed into a motorcycle

00:15:03and you have the ability to stand off the pegs

00:15:07or wherever it's happening,

00:15:11I think that's pretty darn impressive.

00:15:13Well, you still see people doing it in MotoGP.

00:15:16Yeah.

00:15:16Just raising their back up until the air coming off the screen

00:15:20can attach to the rider's back.

00:15:23Yeah.

00:15:24Rather than separating into a mass,

00:15:27a sheet of energy-eating forces.

00:15:31Yeah.

00:15:32The other thing that came to me,

00:15:33while you were talking about instability,

00:15:35we were talking about weave or shimmy

00:15:37and centers of pressure,

00:15:40it was an, I think it was an Eric Bostrom story,

00:15:43and you had observed Eric at Daytona

00:15:46on the banking and the bike would start to weave

00:15:51and he would get out of the saddle.

00:15:54He would take his ass off the saddle,

00:15:56lighten up, put more pressure on the pegs

00:15:58and hang on to the bars.

00:16:00And he became the damper for that system

00:16:02rather than being the weight on it

00:16:04that was starting to feed back in it.

00:16:06Yeah.

00:16:07And he got off the saddle and stabilized the bike.

00:16:10That was his comeback ride after his time at Honda.

00:16:13He rode the Kawasaki at Daytona

00:16:16and he said,

00:16:18I couldn't have stopped doing that pumping.

00:16:21That's rider talk at that time

00:16:23for the weave oscillation,

00:16:25which is the rear of the bike,

00:16:27two or three cycles per second.

00:16:29And he said,

00:16:30then I found that if I kind of took my weight off the seat,

00:16:34it would settle down.

00:16:35So he said,

00:16:35I rode the whole 200 miles that way standing up.

00:16:38And these people are in shape.

00:16:44Yeah.

00:16:45They're not just young guys

00:16:49who have quick wrists

00:16:52and a taste for risk.

00:16:56They are doing everything they can

00:16:58to improve their performance.

00:17:00Oh, there was a physio many years ago

00:17:05when Biagi and Rossi were still,

00:17:08you know, heated rivals in Grand Prix.

00:17:11And he was instrumenting riders

00:17:13while they were racing.

00:17:15And Rossi would run,

00:17:17you know,

00:17:17something fairly astronomical

00:17:19during a race like 180.

00:17:22Heart rate,

00:17:23which is quite a lot.

00:17:24You know,

00:17:24if I hit 140 at the gym,

00:17:27I'm like,

00:17:28you know,

00:17:30I'm feeling,

00:17:31feeling it.

00:17:31And,

00:17:32but you know,

00:17:33I'm not,

00:17:33I'll say I'm not in the best shape of my life,

00:17:37but

00:17:38Biagi would run 200,

00:17:42220,

00:17:43like he would,

00:17:44and you could see that in their personalities,

00:17:46right?

00:17:46Like Rossi's kind of the mentally,

00:17:49the more cruisy guy.

00:17:50And Biagi was like,

00:17:51really?

00:17:52He seemed strong,

00:17:53pretty,

00:17:53pretty tight.

00:17:54But the guys today,

00:17:55they train like pro cyclists,

00:17:58you know,

00:17:58they're ripping heart rates and they're,

00:18:00and they're doing the same thing.

00:18:01Most of those guys,

00:18:01I think are 180,

00:18:03175.

00:18:04And in that range,

00:18:05and they're all just lean as could be,

00:18:07you know,

00:18:08just.

00:18:09And of course,

00:18:10the people back in the pits are looking at your lap times the whole time.

00:18:13And if,

00:18:13if they see that you're wheezing out,

00:18:15you're going to hear about it.

00:18:17Yeah.

00:18:18When,

00:18:19when Lawson went over for the first time,

00:18:22Kenny told him at the end of the year,

00:18:25you,

00:18:26you let down the side,

00:18:27you're just not in good enough shape.

00:18:29And Lawson trained like a maniac.

00:18:31And he got into that 180 heart rate club.

00:18:35And just became a,

00:18:38a beast.

00:18:39Oh,

00:18:40Matt was,

00:18:40was the same.

00:18:42And he,

00:18:42he always had,

00:18:43he,

00:18:43Matt would,

00:18:44Matt Mladen would always say that he wasn't the most talented rider in the

00:18:47paddock,

00:18:47but he could outwork anyone.

00:18:49And there was,

00:18:50there was this lore at the time where he would,

00:18:53he would allow himself one latte per week.

00:18:58Like he wouldn't,

00:19:00I mean,

00:19:00just really.

00:19:01And then,

00:19:01you know,

00:19:02to have somebody like Anthony Gobert coming along,

00:19:04he was just like Mac and cheeseburgers and just drinking his brains out.

00:19:08And to come and barely be able to zip his leathers up and go out and do a few

00:19:14laps at the very end of qualifying.

00:19:16Cause he showed up late.

00:19:17They're like,

00:19:18where's Anthony?

00:19:18This is Terry Vance.

00:19:19Who's very like Terry really is a very supportive top guy,

00:19:24right?

00:19:24Like he really wants people to succeed.

00:19:26And you got Gobert.

00:19:27He doesn't know where Gobert is.

00:19:29And then Anthony shows up like minutes before the end of qualifying,

00:19:32gets on the bike,

00:19:33goes out,

00:19:34does some laps,

00:19:35comes back,

00:19:36is heaving and sweating and lays down.

00:19:39And he's like,

00:19:40how do we do?

00:19:40And he's like,

00:19:41a lap record.

00:19:42Okay,

00:19:42great.

00:19:43Yeah.

00:19:43Because this man must've had some group of mutations that were,

00:19:50let's do it to this guy.

00:19:51Yeah.

00:19:52And it didn't mean anything to it,

00:19:55but anyway,

00:19:55we're,

00:19:56we're getting far off the topic here.

00:19:58I love getting off topic,

00:19:59Kevin.

00:20:00Come on.

00:20:00Well,

00:20:01yes,

00:20:02but we promised them something.

00:20:04We've got to get back to it.

00:20:05What's wrong with the damn modern motorcycle?

00:20:07Why is it so slow?

00:20:09Oh,

00:20:09so slow.

00:20:10So I thought,

00:20:10okay,

00:20:11let's do the calculation for really cleaning this thing up to sort of propeller

00:20:18driven airplane standard.

00:20:22Same horsepower,

00:20:24same frontal area,

00:20:26349 miles per hour.

00:20:29Yeah.

00:20:29Now we're talking.

00:20:30Now we're talking.

00:20:32So,

00:20:33uh,

00:20:34we're just glad that we don't do that because the faster you are going at the

00:20:43end of the straightaway,

00:20:44the sooner you have to break.

00:20:46And these motorcycles,

00:20:48this powerful,

00:20:49a motorcycle with this much drag is making the front wheel light to the

00:20:55point that this whole winglet revolution was about keeping the front end

00:21:00down without having to,

00:21:02the system,

00:21:03the anti-wheeling system,

00:21:05uh,

00:21:06roll the throttle off a little bit.

00:21:09So,

00:21:10uh,

00:21:11we're,

00:21:12we're not going,

00:21:13it's,

00:21:13it's not a real,

00:21:15realistic expectation that we would reach 349 miles.

00:21:18249 miles per hour anywhere,

00:21:20but that's what,

00:21:24uh,

00:21:24the horsepower that I was,

00:21:27I,

00:21:27I subtracted some for rolling resistance and some for winglets and so on.

00:21:31So I ended up with 245 horsepower.

00:21:33And so there's,

00:21:38there's potential out there.

00:21:41Uh,

00:21:42but again,

00:21:43the motorcycle like ourselves is a massive compromises.

00:21:47We'd love to put the streamlined tail on there,

00:21:50but there are problems with it,

00:21:54which would have to be solved.

00:21:57And so people aren't kicking too much over these 1958 regulations,

00:22:04which say no streamlining behind the rider and no streamlining,

00:22:09um,

00:22:10um,

00:22:11forward of a plane,

00:22:14a vertical plane,

00:22:1650 millimeters ahead of the front axle.

00:22:19I think it was a hundred.

00:22:21Then they,

00:22:21they took some back.

00:22:23Not sure why,

00:22:24but this is one of the things about going racing is you get the rule book and you look at it and you think,

00:22:32wow,

00:22:32why did they do that?

00:22:34Why did they do this?

00:22:35Because often somebody's got a,

00:22:38someone's name is on some of these rules.

00:22:42Nixon,

00:22:42uh,

00:22:43wondered how he was going to run his tack wire from the engine to the tachometer.

00:22:48The tachometer is up in front of the tack wire goes out of it straight at the number plate.

00:22:53So he drilled a hole in the number plate,

00:22:55ran the tack wire through it.

00:22:56Oh,

00:22:57you're disqualified.

00:22:58You can't,

00:22:59no,

00:22:59you can't race with that.

00:23:01So,

00:23:02you know,

00:23:02what are you going to do?

00:23:03You just need a sense of humor,

00:23:06officialdom,

00:23:07nod and smile and resolve to get away with as much as you possibly can.

00:23:14Well,

00:23:15that's,

00:23:15that's racing clearance.

00:23:17We're not two millimeters over.

00:23:20Interpretation.

00:23:20Yeah.

00:23:22Um,

00:23:22then of course the internal combustion engine is the terrible,

00:23:27uh,

00:23:28scandal,

00:23:28which is that roughly 25%,

00:23:32kind of like the human body,

00:23:35roughly 25% of the fuel taken in actually produces mechanical work.

00:23:41Okay.

00:23:42Oh boy.

00:23:43There's room for improvement.

00:23:44Yeah.

00:23:45Plenty of room for improvement.

00:23:47Um,

00:23:49the MotoGP bike,

00:23:50because it has a high compression and a lot of measures have been taken to eliminate,

00:23:55uh,

00:23:56sources of,

00:23:57uh,

00:23:58friction and loss,

00:24:00uh,

00:24:01runs a bit higher than that.

00:24:0325,

00:24:04I'm sure.

00:24:05But step up to diesel.

00:24:07There are diesel automobiles that you can buy should you have the money that read.

00:24:15Well,

00:24:17the spark ignition gasoline burner uses roughly half a pound of fuel per horsepower developed for one hour.

00:24:27This is called the brake specific fuel consumption or SFC 0.5 corresponding to 25% efficiency.

00:24:37If we step to diesel,

00:24:39we get an automobile with 0.42.

00:24:43If we step back in time to the 1950s,

00:24:49there was the right turbo compound engine on late model constellations and the Douglas DC-7 0.38,

00:25:00because it had three little turbines driven by the exhaust and they weren't turbochargers.

00:25:09They were geared back to the crankshaft.

00:25:12So they were using waste energy in the exhaust to help drive the propeller.

00:25:20Amazing.

00:25:21And 0.38.

00:25:22That's good.

00:25:24But,

00:25:24uh,

00:25:25first of all,

00:25:26the FIM aren't going to let us put power recovery turbines on our engine.

00:25:32And second of all,

00:25:33where would we put them?

00:25:34And all the hot plumbing that they involve.

00:25:36There's all sorts of things we could do.

00:25:41You're smashing my dreams,

00:25:43Kevin.

00:25:43Come on.

00:25:43Don't be practical.

00:25:45Don't be practical.

00:25:47Um,

00:25:48the most efficient diesels are the ones that drive international trade.

00:25:54They're engines that have like four foot bore and six foot stroke.

00:25:59And their efficiency is like 0.5,

00:26:03uh,

00:26:040.53 is the efficiency.

00:26:06And they use a quarter of a pound of fuel per horsepower per hour.

00:26:13And then stepping beyond that,

00:26:16um,

00:26:17the eco people don't like,

00:26:19uh,

00:26:21anything that burns something.

00:26:24So.

00:26:24They don't like combined cycle gas turbine electricity generating plants,

00:26:33even though they are now 60% efficient.

00:26:39And the great thing about,

00:26:41uh,

00:26:42natural gas,

00:26:43which they generally burn is that each molecule of methane,

00:26:48which makes up most of natural gas is one atom of carbon joined to four.

00:26:55Hydrogen atoms.

00:26:56So it has the least carbon per unit of heat output of any,

00:27:03uh,

00:27:03practical fuel.

00:27:05Well,

00:27:06we won't be satisfied with anything less than perfection.

00:27:11Okay.

00:27:11What else could we do?

00:27:13There's all this heat is pouring out of this power plant so much so that

00:27:19people that are following in our draft are cooking their front tires.

00:27:23Um,

00:27:25and I,

00:27:27I was tipped off to this by seeing the guys lining up at,

00:27:32at Motegi to do their end of practice clutch starts.

00:27:38And they're sitting there with the engine running.

00:27:40It was a still day.

00:27:41And you could see this column of distortion rising from each bike,

00:27:46all that heat.

00:27:48And of course they're sitting there idling.

00:27:50Good time for the toaster analogy.

00:27:52I think.

00:27:53Yeah.

00:27:54Every horsepower is 746 Watts,

00:27:58which incidentally is the power of a kitchen toaster.

00:28:00So when we look at where the energy goes in a spark ignited piston engine,

00:28:10we've got 25 or 30% that produces mechanical power.

00:28:15We've got a third that goes to the cooling system because if we don't cool the piston crown,

00:28:24the inside of the combustion chamber,

00:28:26the cylinder walls,

00:28:27the oil will boil away.

00:28:29The material will rise to a temperature at which it fails.

00:28:32So all these parts are cooled.

00:28:36That becomes waste heat.

00:28:38It is heat that is not beating on piston crowns and pulling chain in at a tremendous rate and driving the rear wheel.

00:28:46Pardon me,

00:28:47shaft drive folks.

00:28:51Anyway,

00:28:53this heat loss is partly the oil cooler is there as well.

00:29:02Mark was talking about what happens when we spray all this cooling oil up at the underside of the piston.

00:29:11We're doing this because we've made the piston so light that it can't get rid of its own heat by conduction.

00:29:18It's too thin.

00:29:20Conduction to the cylinder walls.

00:29:22To the cylinder walls.

00:29:22Which is the normal biggest path out of the piston.

00:29:27It is not cooled to any significant extent by crankcase air.

00:29:32Because that air is pretty hot itself.

00:29:35And what determines which way heat flows is the difference in temperature between the hot thing and the cold thing.

00:29:44Called delta T.

00:29:46And there isn't much in the crankcase.

00:29:48No.

00:29:48Ideally,

00:29:50all of the heat

00:29:52would be used

00:29:54from combustion

00:29:55would be used to push the piston down.

00:29:57Absolutely.

00:29:57It wouldn't be rejected into the engine around.

00:30:01That's not practical.

00:30:02We have lots of coatings now.

00:30:03The guys,

00:30:04I talked to a race engine builder who's building Cosworth,

00:30:06like old Cosworth and other things.

00:30:08And it's like,

00:30:09he's putting slippery stuff on the piston skirts

00:30:12and he's got

00:30:12heat rejecting coatings on the tops of the pistons.

00:30:15And he's doing the

00:30:16combustion chambers

00:30:17with these high zoot,

00:30:18you know,

00:30:19aerospace-y kind of coatings.

00:30:21And it's all in an effort to keep the heat

00:30:23in the chamber

00:30:24so that it pushes down.

00:30:26Well,

00:30:26we can't let the exhaust gas

00:30:28completely cool either,

00:30:29right?

00:30:29It's not,

00:30:30you know,

00:30:31we can't.

00:30:31Because,

00:30:32imagine,

00:30:33the piston makes its stroke.

00:30:35At some point,

00:30:37maybe 50 degrees

00:30:39before bottom center,

00:30:40the exhaust valves begin to lift.

00:30:43So,

00:30:44the pressure in the cylinder drops rapidly.

00:30:47Well,

00:30:48let's look at the PV diagram,

00:30:50pressure versus volume.

00:30:53Oh,

00:30:53it says here that we've got

00:30:55most of 100 PSI

00:30:56at the moment of exhaust valve lifting.

00:30:59Wait,

00:31:00that's valuable energy.

00:31:02Okay,

00:31:03let's make the stroke twice as long

00:31:05and expand it twice as far.

00:31:07Now,

00:31:07we'll have to cut down peak revs

00:31:09because

00:31:10piston peak acceleration

00:31:12is directly proportional

00:31:13to stroke length.

00:31:16Double the stroke,

00:31:18double the stress.

00:31:19We've already got

00:31:2011,000 G's

00:31:22at top dead center

00:31:23at 18,000 RPM.

00:31:2622,000 G's?

00:31:28I don't think so.

00:31:30Not this week.

00:31:31And that's how a turbo helps.

00:31:32That's how a turbo,

00:31:33or what Kevin was talking about

00:31:34with the aircraft engine

00:31:36that's putting energy

00:31:37back into the crank.

00:31:38It's using that heat

00:31:39and pressure energy

00:31:40to spin something

00:31:42that puts something...

00:31:43To push more air

00:31:43into the engine.

00:31:44Pushes some energy back.

00:31:45Because power

00:31:45is not only

00:31:47proportional to

00:31:48piston displacement,

00:31:50but also to how much

00:31:52mixture you can

00:31:53cram into it.

00:31:54And if you use a pump,

00:31:55a turbocharger,

00:31:56a supercharger,

00:31:57is proportional to the volume

00:32:00of mixture

00:32:00that you can burn.

00:32:04Well, the U.S. Army

00:32:05decided

00:32:05this is

00:32:07too much.

00:32:10They adopted

00:32:10a thing called

00:32:11the single-fueled

00:32:13battlefield

00:32:14years and years ago.

00:32:16Drones,

00:32:17jeeps,

00:32:19tanks,

00:32:20airplanes

00:32:20all have to run

00:32:21on the same fuel

00:32:22so that

00:32:22if you're out

00:32:24of fuel,

00:32:25the chances

00:32:25you can find

00:32:27a drum of fuel

00:32:28are pretty good.

00:32:30That fuel will burn

00:32:31in your vehicle.

00:32:32Just think of the inventory

00:32:33problems

00:32:34of having...

00:32:35You know,

00:32:36it's like...

00:32:36Like World War II.

00:32:37They had red gas,

00:32:38they had purple gas,

00:32:39they had blue gas

00:32:41or some other color.

00:32:43Red gas

00:32:44was for jeeps.

00:32:45That was the stuff

00:32:46you can hear it

00:32:47knocking in the can.

00:32:48So,

00:32:51all this stuff

00:32:52had to be kept separate.

00:32:54And of course,

00:32:55diesel for

00:32:55such tanks

00:32:58as had diesel engines.

00:33:00Strangely,

00:33:01although

00:33:01the Germans

00:33:03were the early

00:33:04hotbed

00:33:08of diesel

00:33:09development,

00:33:10in World War II

00:33:11their tanks

00:33:13burned gasoline.

00:33:15And it was

00:33:15the Soviets

00:33:16whose tanks

00:33:17were diesel.

00:33:18Figure that out.

00:33:20Anyway,

00:33:21there have been

00:33:24experiments made

00:33:25with long-distance

00:33:26trucking

00:33:27in Europe

00:33:27with recovering

00:33:28exhaust heat

00:33:29and using it

00:33:30to raise steam

00:33:31and running

00:33:33that steam

00:33:33through a turbine

00:33:34which helps

00:33:35to drive the truck.

00:33:37Well,

00:33:39that's okay

00:33:42for a system

00:33:43that's going

00:33:43to run

00:33:44for long periods

00:33:45at

00:33:46a constant

00:33:48power level.

00:33:49For example,

00:33:51combined cycle

00:33:52gas turbine

00:33:54electricity

00:33:54generating plants.

00:33:56A gas turbine

00:33:56puts out

00:33:57a huge

00:33:58hot breath.

00:33:58Anyone that's

00:33:59been around

00:34:00jet engines

00:34:01or helicopters

00:34:01knows that

00:34:03that hot

00:34:04roast fuel

00:34:06smell

00:34:06is hot air

00:34:08from the engine.

00:34:10They run that

00:34:11through a heat exchanger.

00:34:12they raise steam.

00:34:14They drive

00:34:14a steam turbine

00:34:17with it

00:34:17and it sits

00:34:18there generating

00:34:19all this power

00:34:2060% efficiency

00:34:22which is

00:34:23outstanding.

00:34:24well,

00:34:27they haven't

00:34:29adopted it

00:34:30for trucks

00:34:30widely.

00:34:32What are

00:34:32the chances

00:34:33of deciding

00:34:34that we

00:34:35could put,

00:34:36we could recover

00:34:36exhaust heat

00:34:37on a motorbike

00:34:38with a steam

00:34:40bottoming cycle?

00:34:41We'll run

00:34:41the exhaust

00:34:42and a heat

00:34:43exchanger

00:34:43and then the,

00:34:44oh dear.

00:34:47Well,

00:34:47I think one

00:34:48way that we

00:34:49have tried

00:34:49to do

00:34:50things like

00:34:51that is

00:34:51the fabled

00:34:53rear radiator

00:34:54running the air

00:34:56through the motorcycle

00:34:57and into a radiator

00:34:58that's exhausting

00:34:59its heat

00:35:01into the,

00:35:02because a radiator

00:35:03is potentially

00:35:04a jet engine

00:35:05of low grade.

00:35:06Yes.

00:35:06And you see

00:35:07the exhaust pipes

00:35:08on,

00:35:09you know,

00:35:09on MotoGP bikes,

00:35:10not all of them

00:35:11but many of them

00:35:12have it

00:35:12right at the end

00:35:14of the tail section

00:35:14exhausting

00:35:16straight into

00:35:17the lower

00:35:18pressure area

00:35:19and maybe

00:35:20we would get

00:35:21a notional increase.

00:35:22Well,

00:35:23in World War II

00:35:23the fighter planes

00:35:26with V-12 engines

00:35:28had rear directed

00:35:29exhaust stubs

00:35:31on each cylinder

00:35:32and

00:35:33I learned

00:35:36that

00:35:37they got

00:35:38about 400

00:35:39horsepower

00:35:40worth of jet thrust.

00:35:42Get out.

00:35:44Wow.

00:35:45Good one,

00:35:46huh?

00:35:46Yeah.

00:35:47So for bomber

00:35:48engines

00:35:48and for

00:35:49cargo planes

00:35:50which need

00:35:51to sit up

00:35:52at high altitude

00:35:52where the air

00:35:53doesn't hold

00:35:54you back much

00:35:55they're going

00:35:57to need

00:35:58a compressor

00:35:59to restore

00:36:01sea level

00:36:02density

00:36:03to the cylinder

00:36:04filling.

00:36:06Turbochargers.

00:36:07Turbo

00:36:08normalizing.

00:36:09Yes.

00:36:10V-17s

00:36:11all turbocharged.

00:36:13V-24s,

00:36:13V-29

00:36:14up there

00:36:15at high altitude

00:36:16with those turbos

00:36:17humming away

00:36:19compressing air

00:36:20to make

00:36:21the engines

00:36:22more powerful

00:36:23even though

00:36:24the altitude

00:36:25loss of density

00:36:27is considerable

00:36:28at 30,000 feet.

00:36:31So

00:36:31there are all

00:36:33kinds of ways

00:36:33that we could

00:36:34get more

00:36:35from the fuel

00:36:36that we put

00:36:40into our motorcycles

00:36:40but they are

00:36:41complicated.

00:36:42They are

00:36:43expensive.

00:36:43They don't

00:36:44work

00:36:45except

00:36:45at constant

00:36:47power level.

00:36:49So it's

00:36:49oh

00:36:51what about

00:36:51turbocharging

00:36:52motorcycles?

00:36:53Works very well

00:36:54for drag racing

00:36:54and for record

00:36:55setting.

00:36:56But I remember

00:36:57seeing a race

00:36:59at mid-Ohio

00:37:01the man

00:37:03on the microphone

00:37:04was going nuts

00:37:05about these

00:37:06turbo bikes

00:37:07that were just

00:37:07going to set

00:37:08things on fire.

00:37:09So the race

00:37:10started

00:37:10the turbine

00:37:11bikes

00:37:11they disappeared

00:37:13into turn one

00:37:14and

00:37:15after the

00:37:17tumult

00:37:18there was

00:37:20quiet.

00:37:22And then

00:37:22here came

00:37:23the field

00:37:24no turbo

00:37:26bikes.

00:37:28A few

00:37:28seconds later

00:37:29here they came

00:37:30being very careful

00:37:31at each corner.

00:37:34Turbochargers

00:37:35as simple

00:37:37turbochargers

00:37:38that do not

00:37:39have

00:37:40electric

00:37:42electronic

00:37:44control

00:37:44of boost

00:37:45have

00:37:47terrible

00:37:47steep

00:37:48torque curves

00:37:49like those

00:37:50of two

00:37:50strokes

00:37:50and tend

00:37:52to throw

00:37:53the rider

00:37:54off.

00:37:55Yeah Formula

00:37:55USA gave

00:37:57a very open

00:37:57you know

00:37:58this is sort

00:37:59of circa

00:37:5995-2000

00:38:01somewhere in

00:38:01that range.

00:38:02They had a

00:38:02very open

00:38:03rule plan

00:38:05and you

00:38:05could bring

00:38:05your turbo

00:38:07you could

00:38:07run

00:38:07nitrous

00:38:08nitrous

00:38:09was kind

00:38:10of a neat

00:38:10solution

00:38:10because you

00:38:11could apply

00:38:12it as

00:38:12required

00:38:12you could

00:38:13have your

00:38:13you know

00:38:14corner exit

00:38:14and then

00:38:15get up on

00:38:16the fat

00:38:16part of

00:38:16the tire

00:38:17and then

00:38:17hit the

00:38:17button

00:38:18and get

00:38:18your extra

00:38:19boost

00:38:19but turbo

00:38:22bikes

00:38:22as Kevin

00:38:23points out

00:38:24you know

00:38:24the more

00:38:25you

00:38:25I don't

00:38:25know

00:38:25it's

00:38:26what do

00:38:26you say

00:38:26the faster

00:38:27you go

00:38:27the faster

00:38:27you go

00:38:28and

00:38:29well you'd

00:38:30screw it

00:38:30on and

00:38:30there'd be

00:38:31lag

00:38:31there were

00:38:31all kinds

00:38:32of schemes

00:38:32in cars

00:38:33where they

00:38:33have turbos

00:38:34that had

00:38:34variable

00:38:36vanes

00:38:36and they

00:38:37were trying

00:38:37to control

00:38:38the momentum

00:38:39of the

00:38:40impeller

00:38:40so that you

00:38:41had a more

00:38:41constant boost

00:38:42just putting

00:38:43your thumb

00:38:43over the

00:38:44end of the

00:38:44garden hose

00:38:44that's what

00:38:45it is

00:38:45and trying

00:38:47to keep

00:38:47the pressure

00:38:48more constant

00:38:48so that

00:38:49what you're

00:38:49getting

00:38:50what does

00:38:50a rider

00:38:50want

00:38:51a rider

00:38:51wants a

00:38:52torque

00:38:52rheostat

00:38:52yep

00:38:53absolutely

00:38:54predictable

00:38:55amount of

00:38:56torque

00:38:56for how

00:38:56much I'm

00:38:57turning it

00:38:57and if

00:38:58I'm

00:38:58if I'm

00:38:59rolling it

00:39:00on and

00:39:00I'm going

00:39:00up and

00:39:01I'm on

00:39:01the throttle

00:39:02stop I

00:39:02don't or

00:39:03anywhere

00:39:03before that

00:39:04I don't

00:39:05want a

00:39:05massive

00:39:06increase

00:39:06in torque

00:39:07for every

00:39:08100 rpm

00:39:09yes

00:39:10because what

00:39:11happens

00:39:11that's a high

00:39:12side

00:39:13yeah how

00:39:13are you

00:39:13going to

00:39:14control it

00:39:14well the

00:39:16thing that

00:39:17looks really

00:39:18promising here

00:39:19is Honda's

00:39:19electric

00:39:20supercharger

00:39:21because it

00:39:24has a very

00:39:24powerful electric

00:39:25motor on

00:39:27it so

00:39:28that from

00:39:29the

00:39:29instruction

00:39:30go until

00:39:32useful boost

00:39:34or until

00:39:34the boost

00:39:35that the

00:39:36rider wants

00:39:36is very

00:39:37quick that

00:39:39looks like

00:39:40a workable

00:39:42system

00:39:42it does

00:39:43but we

00:39:43we still

00:39:45have to

00:39:45pay for

00:39:45it

00:39:46oh yeah

00:39:46because you

00:39:47got to

00:39:48generate

00:39:48on that

00:39:49motorcycle

00:39:49you have

00:39:50to generate

00:39:50the electricity

00:39:51I put an

00:39:51electric power

00:39:52steering pump

00:39:53on my

00:39:54Jaguar

00:39:54mark 2

00:39:55my 1966

00:39:55Jaguar

00:39:56because I

00:39:56wanted to

00:39:57put the

00:39:57air conditioning

00:39:58compressor

00:39:58where the

00:39:58generator was

00:39:59and move

00:40:00the power

00:40:01steering pump

00:40:01away from

00:40:02this stuff

00:40:03because I

00:40:03put an

00:40:04alternator up

00:40:04high where

00:40:05you can see

00:40:05it and the

00:40:07AC compressor

00:40:07where the

00:40:08generator used

00:40:09to be

00:40:09so I

00:40:09have power

00:40:10and now I

00:40:11have air

00:40:11conditioning

00:40:11but how

00:40:12do I get

00:40:12power steering

00:40:13I found

00:40:13a power

00:40:14steering pump

00:40:14from a

00:40:15Toyota

00:40:15that's

00:40:15electric

00:40:15it's about

00:40:16this big

00:40:18as big

00:40:18as a bottle

00:40:18of gin

00:40:19has a reservoir

00:40:20on top

00:40:21electric pump

00:40:21on bottom

00:40:22its maximum

00:40:24draw is 50

00:40:24amps

00:40:25that's why

00:40:26I need an

00:40:26alternator now

00:40:27and you need

00:40:28big fat

00:40:28cables

00:40:29and when

00:40:29that thing

00:40:30goes

00:40:30you can

00:40:31watch the

00:40:32lights dim

00:40:32you know

00:40:32what I mean

00:40:33if you're

00:40:34really sawing

00:40:35it in a

00:40:36parking lot

00:40:36to turn

00:40:37this compressor

00:40:38on this

00:40:39Honda

00:40:39the V3

00:40:40Honda

00:40:40concept

00:40:40that they're

00:40:41now teasing

00:40:42with moving

00:40:42videos

00:40:43it's going

00:40:43to take

00:40:43horsepower

00:40:43yeah

00:40:44yeah

00:40:44so you

00:40:45got it

00:40:45your alternator

00:40:46is going

00:40:47to go

00:40:47and just

00:40:48really bear

00:40:49down and

00:40:50drive those

00:40:50amps into

00:40:51probably a

00:40:52bigger battery

00:40:53or let's say

00:40:55a higher

00:40:55capacity battery

00:40:56probably lithium

00:40:57in this case

00:40:58just keep

00:40:58the weight

00:40:59down

00:40:59now we're

00:41:00going to

00:41:00say

00:41:01well

00:41:01all the

00:41:03more reason

00:41:03to go

00:41:03electric

00:41:04right now

00:41:05let's go

00:41:05to the

00:41:06dealer

00:41:06forget all

00:41:07this internal

00:41:08combustion

00:41:08let's go

00:41:09electric

00:41:10it is a

00:41:11pain in the

00:41:11ass I have

00:41:11to admit

00:41:12internal

00:41:13combustion

00:41:13yeah

00:41:14because

00:41:15let's face

00:41:17it all

00:41:17the

00:41:17electronic

00:41:19trickery

00:41:20the

00:41:20anti-spin

00:41:21the anti-wheeling

00:41:22the launch

00:41:23control

00:41:23all of that

00:41:25is working

00:41:26to turn

00:41:27the output

00:41:27of an

00:41:28internal

00:41:28combustion

00:41:28engine

00:41:29into

00:41:29an electric

00:41:30motor output

00:41:31controllable

00:41:33smooth

00:41:34predictable

00:41:35internal

00:41:36combustion

00:41:36what makes

00:41:38me think

00:41:39of a

00:41:39battleship

00:41:40with 16

00:41:40inch guns

00:41:41firing them

00:41:42all at

00:41:42once

00:41:42patooey

00:41:43it's a

00:41:45it's a

00:41:46wild

00:41:46release of

00:41:47energy

00:41:47in pulses

00:41:49the internal

00:41:50combustion engine

00:41:50is driven

00:41:51by pulses

00:41:52how do you

00:41:54how do you

00:41:54deal with

00:41:55that

00:41:55well

00:41:55we've done

00:41:56okay

00:41:56we've done

00:41:57oh yeah

00:41:58yeah

00:41:58we've done

00:41:59okay

00:41:59but

00:42:00why not

00:42:01electric

00:42:01motor

00:42:02so

00:42:03we're

00:42:03thinking

00:42:04well

00:42:06um

00:42:07they

00:42:08accelerate

00:42:09well

00:42:09they're

00:42:11hell on

00:42:11tires

00:42:12and brakes

00:42:12because of

00:42:14the weight

00:42:14when I

00:42:15looked at

00:42:16the first

00:42:17electric

00:42:18racer that

00:42:19Dorna was

00:42:20running

00:42:20in their

00:42:21electric

00:42:21race

00:42:22it was

00:42:22an

00:42:23Energica

00:42:23I don't

00:42:24think

00:42:24they're

00:42:24trading

00:42:25any

00:42:25longer

00:42:25no

00:42:26Energica

00:42:27at

00:42:28500

00:42:29189

00:42:30pounds

00:42:31now

00:42:33the

00:42:34riders

00:42:34in MotoGP

00:42:35are

00:42:36complaining

00:42:36now

00:42:37that

00:42:37um

00:42:38357

00:42:39pounds

00:42:40which is

00:42:41the

00:42:41weight

00:42:42the

00:42:42minimum

00:42:42is

00:42:44really

00:42:45a lot

00:42:46of weight

00:42:46for a

00:42:47racing

00:42:47motorcycle

00:42:48well

00:42:48the 500

00:42:49Grand Prix

00:42:49bikes

00:42:50were

00:42:50286

00:42:51pounds

00:42:51that was

00:42:52after the

00:42:53rule that

00:42:53required them

00:42:54to be

00:42:54130

00:42:55kilograms

00:42:55yes

00:42:56before that

00:42:57they were

00:42:57like

00:42:58250

00:42:59something

00:42:59I've

00:43:00only

00:43:00been

00:43:00on a

00:43:01250

00:43:01Grand Prix

00:43:01bike

00:43:02one time

00:43:03but

00:43:03my

00:43:03goodness

00:43:04what a

00:43:05what a

00:43:06thing

00:43:06it was

00:43:06you totally

00:43:07understood

00:43:07the difference

00:43:08between race

00:43:08bikes and street

00:43:09bikes at that

00:43:09point

00:43:10I did

00:43:53by leaps

00:43:54and bounds

00:43:54but in

00:43:55fact they

00:44:02electrolyte

00:44:04battery

00:44:04which is

00:44:05supposed

00:44:05to

00:44:06be a

00:44:08lot

00:44:08safer

00:44:08can be

00:44:09lighter

00:44:10but it's

00:44:11again

00:45:02squared

00:45:02m is

00:45:02mass

00:45:03v is

00:45:04velocity

00:45:05is now

00:45:07going to be

00:45:07turned into

00:45:08waste heat

00:45:09which will

00:45:11trail

00:45:11behind us

00:45:12as hot

00:45:13little

00:45:13vortices

00:45:14streaming

00:45:15off of

00:45:16the

00:45:16brake

00:45:16discs

00:45:17which

00:45:17are

00:45:17up at

00:45:18800

00:45:19centigrade

00:45:19900

00:45:20and

00:45:22the

00:45:23brakes

00:45:23of today

00:45:24are

00:45:24wonderful

00:45:25they

00:45:26aren't

00:45:27sudden

00:45:30like

00:45:30trying

00:45:31very hard

00:45:32big drum

00:45:33brakes

00:45:33were

00:45:34you

00:45:35touch

00:45:36them

00:45:36and they

00:45:37tended

00:45:37to go

00:45:38right

00:45:38to

00:45:38maximum

00:45:39those

00:45:40big

00:45:40ones

00:45:41disc

00:45:43brakes

00:45:43are

00:45:45smooth

00:45:46and

00:45:46progressive

00:45:47they're

00:45:47such an

00:45:48improvement

00:45:48over the

00:45:49past

00:45:49and

00:45:50many

00:45:51refinements

00:45:51have

00:45:52occurred

00:45:52so I

00:45:52think

00:45:53brakes

00:45:53are one

00:45:54of the

00:45:54great

00:45:54accomplishments

00:45:55but

00:46:11front

00:46:12wheel

00:46:12that will

00:46:12allow us

00:46:13to get

00:46:13that energy

00:46:14back

00:46:14in a

00:46:16reusable

00:46:16form

00:46:17now

00:46:19I let

00:46:20my fingers

00:46:21do the

00:46:21walking

00:46:21this morning

00:46:27called

00:46:27YASA

00:46:28I don't

00:46:29know

00:46:29what

00:46:29that's

00:46:31about

00:46:31has

00:46:44from a

00:46:4529

00:46:46pound

00:46:46unit

00:46:47now

00:46:49what that

00:46:49suggests

00:46:50to me

00:46:50is

00:46:51500

00:46:53foot

00:46:54pounds

00:46:54at the

00:46:59but it's

00:47:00getting

00:47:00there

00:47:00pretty

00:47:01close

00:47:01the

00:47:06so

00:47:08it

00:47:10could be

00:51:35combustion

00:51:36I will

00:51:37give them

00:51:37credit

00:51:37for making

00:51:38one of the

00:51:38greatest

00:51:39sounding

00:51:39engines

00:51:40ever

00:51:40even if

00:51:41it didn't

00:51:42make the

00:51:43most

00:51:43power

00:51:43yes

00:51:44this is

00:51:45wonderful

00:52:10song

00:52:10oh

00:52:11I

00:52:11along

00:52:12with

00:52:12a

00:52:12hit

00:52:12or

00:52:12miss

00:52:12engine

00:52:13now

00:52:13well

00:52:14they're

00:52:15an

00:52:15interesting

00:52:15variety

00:52:17because

00:52:18for example

00:52:18they had

00:52:19reciprocating

00:52:20magnetos

00:52:21nothing

00:52:22in the

00:52:22magneto

00:52:23spun

00:52:23great

00:52:26and

00:52:26it

00:52:27could

00:52:27work

00:52:27perfectly

00:52:27well

00:52:28how

00:52:28does

00:52:28a

00:52:28linear

00:52:29motor

00:52:29work

00:52:29that

00:52:31powers

00:52:31those

00:52:31maglev

00:52:32trains

00:52:32anyway

00:52:33the

00:52:36army

00:52:37decided

00:52:37that

00:52:37it was

00:52:37going

00:52:38to do

00:52:38something

00:52:38about

00:52:39this

00:52:39and

00:52:40they

00:52:40decided

00:52:40they

00:52:41were

00:52:41going

00:52:41to

00:52:41build

00:52:41an

00:52:41uncooled

00:52:43engine

00:52:43diesel

00:52:44because

00:52:45it won't

00:52:46work

00:52:46for spark

00:52:46ignition

00:52:47because

00:52:47if you

00:52:47let

00:52:47the

00:52:48insides

00:52:48of the

00:52:48combustion

00:52:49chamber

00:52:49become

00:52:50very

00:52:50hot

00:52:50the air

00:52:51is heated

00:52:52as it

00:52:52enters

00:52:52and it

00:52:53says

00:52:53oh

00:52:53goody

00:52:54we're

00:52:54going to

00:52:54detonate

00:52:55this

00:52:55time

00:52:55and it

00:52:56does

00:52:57but in

00:52:58a diesel

00:52:58okay

00:52:59so

00:53:00they

00:53:01made

00:53:01the

00:53:02they

00:53:02coated

00:53:03the piston

00:53:03crown

00:53:03with

00:53:04zerk

00:53:04oxide

00:53:04and they

00:53:05made

00:53:06everything

00:53:06out of

00:53:06ink and

00:53:07L

00:53:07something or

00:53:07other

00:53:08so that

00:53:09they

00:53:10they

00:53:10were able

00:53:11to build

00:53:11they

00:53:12were able

00:53:13to build

00:53:14and the

00:53:15goal

00:53:16was

00:53:16super

00:53:17efficiency

00:53:17so that

00:53:18there

00:53:18won't

00:53:18have to

00:53:19be so

00:53:19many

00:53:19millions

00:53:20of

00:53:20drums

00:53:20of

00:53:21diesel

00:53:21dragged

00:53:24into a

00:53:25battle

00:53:25zone

00:53:25well

00:53:28the

00:53:30hotter

00:53:30the

00:53:30inside

00:53:31of the

00:53:31combustion

00:53:31chamber

00:53:32operated

00:53:33the

00:53:34harder

00:53:34it

00:53:34was

00:53:35to

00:53:35persuade

00:53:35air

00:53:36to

00:53:36go in

00:53:36because

00:53:36the

00:53:37moment

00:53:37that

00:53:37it

00:53:37touched

00:53:38that

00:53:38hot

00:53:38metal

00:53:38it

00:53:39expanded

00:53:39and

00:53:41if you

00:53:42were trying

00:53:42to push

00:53:43it in

00:53:43with the

00:53:44turbocharger

00:53:44it was

00:53:45getting to

00:53:46be

00:53:47a pretty

00:53:47equal

00:53:48contest

00:53:48well

00:53:49I'm not

00:53:49going in

00:53:50there

00:53:50no matter

00:53:51what you

00:53:51say

00:53:51I'm not

00:53:52going in

00:53:52there

00:53:52it's

00:53:53hot

00:53:53in

00:53:53there

00:53:54and the

00:53:54turbocharger

00:53:55pushing us

00:53:57all in

00:53:58and in

00:53:59the end

00:53:59they decided

00:54:00that

00:54:00they were

00:54:01losing as

00:54:02much

00:54:02power

00:54:03trying to

00:54:04cram

00:54:04pure air

00:54:07that's what

00:54:07a diesel

00:54:08takes in

00:54:08the fuel

00:54:10is injected

00:54:10later

00:54:11to cram

00:54:12pure air

00:54:12into a

00:54:13hot box

00:54:14than they

00:54:15were gaining

00:54:15from

00:54:18cutting the

00:54:19heat loss

00:54:19from the

00:54:21combustion gas

00:54:22yeah

00:54:22so

00:54:23this is

00:54:25another

00:54:25compromise

00:54:26it's

00:54:27sort of

00:54:28like

00:55:17we

00:55:17no

00:55:18we

00:55:19shall

00:55:19not

00:55:19so

00:55:23we

00:55:23can

00:55:24we

00:55:24can

00:55:24we're

00:55:26thinking

00:55:27you know

00:55:27we want

00:55:28we want

00:55:28very very

00:55:29lightweight

00:55:29pistons

00:55:30so that

00:55:31their

00:55:31inertia

00:55:32does not

00:55:33create

00:55:33large

00:55:33bearing

00:55:34loads

00:55:34does

00:55:35not

00:55:35require

00:55:36thicker

00:55:36connecting

00:55:37rods

00:55:37etc

00:55:38but

00:55:39we're

00:55:40spraying

00:55:40oil

00:55:40at the

00:55:41piston

00:55:41to keep

00:55:41it cool

00:55:42that oil

00:55:42is picking

00:55:43up that

00:55:43heat

00:55:43and it's

00:55:44going to

00:55:44the oil

00:55:45cooler

00:55:45that again

00:55:47is sort

00:55:47of like

00:55:48anything you

00:55:49don't want

00:55:50in your

00:55:50apartment

00:55:50just throw

00:55:51it out

00:55:51the window

00:55:51waste

00:55:54heat

00:55:54from

00:55:55everything

00:55:55windage

00:55:57and

00:55:58electrics

00:55:59are no

00:56:00better

00:56:00because if

00:56:01you turn

00:56:01a Tesla

00:56:02upside down

00:56:03and label

00:56:03all the

00:56:04stuff

00:56:04you find

00:56:05that

00:56:05coolant

00:56:06is being

00:56:07circulated

00:56:09in such

00:56:10ways that

00:56:10they're trying

00:56:11to keep

00:56:12some things

00:56:13warm

00:56:13and some

00:56:14things cool

00:56:15and there

00:56:15are little

00:56:15valves

00:56:16and sensors

00:56:17and so

00:56:17forth

00:56:18to keep

00:56:20their

00:56:20compromises

00:56:21on an

00:56:22even keel

00:56:22they need

00:56:23intelligence

00:56:24and that's

00:56:25why our

00:56:26world is

00:56:26run by the

00:56:27equivalent of

00:56:28ECUs

00:56:28something that

00:56:30takes in

00:56:31the data

00:56:31from all

00:56:31the sensors

00:56:32and says

00:56:32oh I

00:56:33can kind

00:56:34of smooth

00:56:34this out

00:56:35and make

00:56:36it work

00:56:36it's

00:56:39marvelous

00:56:40that engines

00:56:41now have

00:56:42mapped

00:56:42ignitions

00:56:43when I

00:56:44had my

00:56:45TD-1

00:56:45which was

00:56:46made in

00:56:461965

00:56:47like all

00:56:49two strokes

00:56:49it had

00:56:50split

00:56:51personality

00:56:52during

00:56:53at lower

00:56:54RPM where

00:56:55the exhaust

00:56:55pipe was

00:56:56not

00:56:56furiously

00:56:57pumping air

00:56:58it needed

00:56:5936 degrees

00:57:00of ignition

00:57:01timing

00:57:01like a

00:57:02four stroke

00:57:03the air

00:57:05in the

00:57:05cylinder

00:57:06the charge

00:57:07in the

00:57:08cylinder

00:57:08was not

00:57:08pure enough

00:57:09to propagate

00:57:11flame any

00:57:11faster than

00:57:12that

00:57:12but then

00:57:13when

00:57:14we got

00:57:15to a

00:57:16higher RPM

00:57:16and the

00:57:17pipe began

00:57:17to

00:57:18it's humming

00:57:20along with

00:57:20the tune

00:57:21and then

00:57:22it begins

00:57:22opens its

00:57:23mouth and

00:57:23begins to

00:57:24sing loudly

00:57:25it's pumping

00:57:27a lot of

00:57:28air

00:57:28suddenly

00:57:28the best

00:57:30ignition

00:57:30timing is

00:57:3115 degrees

00:57:32before top

00:57:33dead center

00:57:33because

00:57:34all those

00:57:35fuel and

00:57:36air molecules

00:57:37in the

00:57:38combustion

00:57:38chamber are

00:57:39so close

00:57:39together

00:57:40they develop

00:57:41a hot

00:57:42relationship

00:57:43very quickly

00:57:44so the

00:57:45flame spread

00:57:45is rapid

00:57:46less ignition

00:57:48timing needed

00:57:48well

00:57:50what did

00:57:50we do

00:57:51we set

00:57:52a

00:57:52compromised

00:57:53timing

00:57:53it made

00:57:55the engine

00:57:55overheat

00:57:56on top

00:57:56and made

00:57:57it weak

00:57:57on the

00:57:58bottom

00:57:58good one

00:58:00so modern

00:58:02engines

00:58:02have an

00:58:04electronic map

00:58:05stored in

00:58:06the ECU

00:58:06which has

00:58:08the correct

00:58:08ignition

00:58:09timing for

00:58:09every

00:58:10throttle

00:58:11opening

00:58:11every

00:58:12RPM

00:58:12it's

00:58:14stored

00:58:15there

00:58:15information

00:58:16was

00:58:18discovered

00:58:19on the

00:58:19dyno

00:58:20and recorded

00:58:20so

00:58:22always

00:58:23the ignition

00:58:24timing is

00:58:24correct

00:58:25the same

00:58:25is done

00:58:26for the

00:58:26fuel

00:58:27this is a

00:58:28wonderful

00:58:28piece of

00:58:29progress

00:58:30because a

00:58:30carburetor

00:58:31was sort of

00:58:32like the

00:58:33fixative sprayer

00:58:34that artists

00:58:34used to

00:58:35spray fixative

00:58:36onto a

00:58:37pastel so

00:58:38that it

00:58:38didn't all

00:58:39blow away

00:58:40if somebody

00:58:40sneezed

00:58:41it's got a

00:58:43tube

00:58:43goes down

00:58:44into a

00:58:45bottle of

00:58:45this stuff

00:58:46and another

00:58:46tube blows

00:58:47across the

00:58:48top of it

00:58:48it

00:58:50pulled

00:58:53droplets up

00:58:54out of the

00:58:54supply tube

00:58:55and broke

00:58:55them up

00:58:56into a

00:58:56mist

00:58:57that's what

00:58:58a carburetor

00:58:59was and

00:58:59it ran

00:59:00rich in

00:59:01the summer

00:59:01and lean

00:59:02in the

00:59:03winter

00:59:03but then

00:59:05the EPA

00:59:06arrived and

00:59:07said

00:59:07mustn't

00:59:09today we

00:59:10have wonderful

00:59:11digital fuel

00:59:12injection that

00:59:13allows

00:59:14the EPA

00:59:16and other

00:59:17such

00:59:17regulatory

00:59:18bodies

00:59:19to feel

00:59:20that they're

00:59:21doing their

00:59:21job

00:59:22and we

00:59:24on the other

00:59:24hand have

00:59:25excellent

00:59:26performance

00:59:26from engines

00:59:27that are

00:59:28equipped with

00:59:29this technology

00:59:30so that's

00:59:31a really good

00:59:32one

00:59:32that's a

00:59:33story for us

00:59:34it is

00:59:34I always

00:59:36mess around

00:59:37with carburetors

00:59:38carburetors on

00:59:39my XS650

00:59:40my Norton

00:59:41Commando

00:59:42take a drink

00:59:42Velocet

00:59:43it's a

00:59:44priesthood

00:59:44it's fascinating

00:59:45once you're

00:59:46in

00:59:46you're always

00:59:47in

00:59:47the first

00:59:49time I

00:59:49looked inside

00:59:50of a

00:59:51Triumph

00:59:51TR6

00:59:52car

00:59:53engine

00:59:54I took

00:59:54off the

00:59:54air filter

00:59:55and I

00:59:56was like

00:59:57huh

00:59:57and I

00:59:57got on

00:59:57the

00:59:57linkage

00:59:58and I

00:59:58was looking

00:59:58inside

00:59:59and I

00:59:59revved

00:59:59the engine

01:00:00and I

01:00:01was like

01:00:01holy moly

01:00:02like

01:00:03watching

01:00:04the fuel

01:00:05just whisk

01:00:06out in

01:00:07this white

01:00:07mist

01:00:07from the

01:00:08main jet

01:00:08I was like

01:00:09wow

01:00:09these are

01:00:09Stromberg

01:00:10carburetors

01:00:11they're like

01:00:11a

01:00:11CB carburetor

01:00:13just like

01:00:13you'd find

01:00:14on a lot

01:00:14of motorcycles

01:00:15with a

01:00:15rubber

01:00:15diaphragm

01:00:16and one

01:00:16orifice

01:00:17for fuel

01:00:18to be

01:00:18delivered

01:00:19the center

01:00:19jet

01:00:20and then

01:00:20the piston

01:00:22moves up

01:00:22and down

01:00:22through air

01:00:24running through

01:00:25the carburetor

01:00:26making a

01:00:26vacuum in a

01:00:27chamber that's

01:00:27sealed by that

01:00:28rubber

01:00:28diaphragm

01:00:29and yeah

01:00:31it was

01:00:31remarkable

01:00:32then

01:00:33you know

01:00:34we're into

01:00:34the world

01:00:35of modern

01:00:35technology

01:00:36and I

01:00:36had a

01:00:361958

01:00:37MG

01:00:37Magnet

01:00:39which is a

01:00:39four door

01:00:40saloon

01:00:40very proper

01:00:41British

01:00:42looking

01:00:42thing

01:00:42and it

01:00:44had a

01:00:441500

01:00:45cc

01:00:46inline

01:00:46four

01:00:46like

01:00:46they

01:00:46use

01:00:47in

01:00:47the

01:00:47MGA

01:00:47and it

01:00:48had

01:00:48twin

01:00:49carburetors

01:00:49inch

01:00:50and a

01:00:50half

01:00:51or inch

01:00:51and a

01:00:52quarter

01:00:53SUs

01:00:54variable

01:00:54height

01:00:55jet

01:00:55so I

01:00:56rebuilt

01:00:56those

01:00:57to the

01:00:57nth

01:00:58degree

01:00:58and I

01:00:58got the

01:00:58jets

01:00:59perfectly

01:00:59centered

01:01:00because

01:01:00it's

01:01:00all

01:01:00mechanical

01:01:00on

01:01:01those

01:01:01you

01:01:01have

01:01:02nut

01:01:02and

01:01:03center

01:01:03the

01:01:03jet

01:01:03so

01:01:04it

01:01:04doesn't

01:01:04rub

01:01:04on

01:01:04the

01:01:04needle

01:01:05I

01:01:05did

01:01:05all

01:01:05of

01:01:05that

01:01:11better

01:01:12but

01:01:12the

01:01:12fueling

01:01:12was

01:01:12off

01:01:13and

01:01:13so

01:01:13I

01:01:13started

01:01:14and

01:01:14I

01:01:14said

01:05:23let's

01:05:26lower

01:05:26horsepower

01:05:27bikes

01:05:27we don't

01:05:28we don't

01:05:29just strap

01:05:30the thing

01:05:31down

01:05:31because

01:05:31you're

01:05:31not

01:05:31really

01:05:32worried

01:05:33about it

01:05:33spinning

01:05:33the tire

01:05:34but I

01:05:34have done

01:05:34turbo

01:05:35high

01:05:35cabooses

01:05:35and stuff

01:05:36where you're

01:05:36using tie

01:05:37down straps

01:05:38to hold

01:05:39the bike

01:05:39back

01:05:39because it

01:05:41wants to

01:05:41go forward

01:05:42so hard

01:05:42even though

01:05:42you're in

01:05:43the front

01:05:43truck

01:05:44front chalk

01:05:44you're

01:05:45exerting

01:05:45so much

01:05:45force

01:05:46that you

01:05:46need to

01:05:47sort of

01:05:47distribute

01:05:48it

01:05:48everywhere

01:05:49and that

01:05:50is not

01:05:50a tire

01:05:50if you

01:05:51use that

01:05:51tire

01:05:51to run

01:05:52that

01:05:52horsepower

01:05:52400

01:05:54something

01:05:56you don't

01:05:56want to

01:05:57use that

01:05:57tire to

01:05:57ride around

01:05:58on as

01:05:59Kevin's

01:05:59pointing out

01:06:00so I

01:06:01think that's

01:06:02why there

01:06:02there's this

01:06:04estimate

01:06:04that says

01:06:0515%

01:06:06loss

01:06:06between

01:06:07the

01:06:07engine

01:06:07and the

01:06:08roller

01:06:09I can't

01:06:10say that

01:06:10I've ever

01:06:10measured

01:06:11that but

01:06:11what we

01:06:11see

01:06:12consistently

01:06:13over

01:06:15is

01:06:16the

01:06:17say

01:06:18it makes

01:06:19and we

01:06:20see

01:06:2212

01:06:23X

01:06:23minus

01:06:2315%

01:06:24there's

01:06:28of course

01:06:31there's

01:06:32rolling

01:06:32loss

01:06:33on the

01:06:34highway

01:06:34tire

01:06:35loss

01:06:36and that's

01:06:36why all

01:06:37this talk

01:06:37about

01:06:38sticky

01:06:41tires

01:06:41cost you

01:06:43top end

01:06:44that used

01:06:45to be the

01:18:10they

01:18:14the

01:18:14crankshaft

01:18:15main

01:18:16bearings

01:18:16were made

01:18:17like

01:18:17pillow

01:18:17blocks

01:18:18they

01:18:19had

01:18:19two

01:18:21them

01:18:21and

01:18:22the

01:18:25so

01:18:26there

01:18:26was

01:18:26nothing

01:18:28enclosing

01:18:29crank

01:18:30case

01:18:30that

01:18:31was

01:18:31all

01:18:31standing

01:18:32back

01:18:33allowing

01:18:34the

01:18:35oil

01:18:35being

01:18:35thrown

01:18:35off

01:18:36to

01:18:37run

01:18:38down

01:18:38the

01:18:39sides

01:18:39where

01:18:40it

01:18:40was

01:18:41no

01:18:41longer

01:18:41close

01:18:42enough

01:18:42to

01:18:42the

01:18:42crank

01:18:43to

01:18:43be

01:18:43accelerated

01:18:44by

01:18:45the

01:18:45windage

01:18:45well

01:18:46there's

01:18:46you know

01:18:47the

01:18:47hot rod

01:18:48guys

01:18:48windage

01:18:48tray

01:18:49you know

01:18:49they would

01:18:50make a

01:18:50thing

01:18:50that was

01:18:51very

01:18:51like a

01:18:52plate

01:18:52that

01:18:52went in

01:18:53between

01:18:53typically

01:18:53went in

01:18:54between

01:18:54the oil

01:18:54pan

01:18:55and the

01:18:55bottom

01:18:56of the

01:18:56engine

01:18:56block

01:18:57which

01:18:58would have

01:18:58pillow

01:18:58blocks

01:18:58like you're

01:18:59talking about

01:18:59bolt on

01:19:00mains

01:19:00and they

01:19:01would put a

01:19:02plate that

01:19:02kind of

01:19:03followed the

01:19:03slots and

01:19:05everything in the

01:19:05crank and allowed

01:19:06the engine to

01:19:07spin but it was to

01:19:08hopefully capture

01:19:09flinging oil and

01:19:11keep it away from

01:19:12the crank so that it

01:19:12wasn't getting

01:19:13churned around

01:19:13and around

01:19:14you mentioned

01:19:15the other day

01:19:16ox5 the

01:19:17aircraft engine

01:19:18yeah

01:19:18having uh

01:19:20screens in the

01:19:20interior of the

01:19:21crankcase that

01:19:22were standing

01:19:23off you know

01:19:24whatever whatever

01:19:25fit a half

01:19:26inch an inch

01:19:26something that

01:19:28would capture

01:19:29that flying oil

01:19:30and keep it from

01:19:31going back

01:19:31perforated metal

01:19:32perforated metal

01:19:34and allowed it to

01:19:35go on the

01:19:35crankcase side

01:19:37and drain

01:19:38rapidly back

01:19:39to the

01:19:40scavenge pump

01:19:41to the

01:19:42scavenge pump

01:19:42and that's

01:19:45why a lot of

01:19:45race cars you

01:19:46know they

01:19:46there are there

01:19:48have been plenty

01:19:49of examples of

01:19:49engines that have

01:19:50been uh wet

01:19:52sump engines that

01:19:53convert they've been

01:19:53dry sumped and

01:19:55they make an

01:19:57adaption of the

01:19:58engine so that you

01:19:59have a separate

01:19:59oil tank and a

01:20:02pump furiously

01:20:03pumping out the

01:20:04oil and maybe

01:20:05reducing the

01:20:05crankcase pressure

01:20:06and letting the

01:20:07oil go back to a

01:20:08tank

01:20:09that maybe has

01:20:09big fins or

01:20:10some cooling

01:20:11ability and then

01:20:12pumping fresh

01:20:13oil back into

01:20:14the pressure pump

01:20:14it has been

01:20:15known that

01:20:17some manufacturers

01:20:18some constructors

01:20:20of racing engines

01:20:21have made

01:20:22tiltable dynos

01:20:24so that they

01:20:25can simulate

01:20:26the acceleration

01:20:27of the vehicle

01:20:29and see where

01:20:30the oil goes

01:20:31so the thing

01:20:33is sitting there

01:20:33on the dyno

01:20:34cranking out

01:20:35hundreds of

01:20:35horsepower and

01:20:36they tip the

01:20:37thing up

01:20:38and watch

01:20:40all the oil

01:20:41pressures

01:20:41because

01:20:43there's that

01:20:44period

01:20:44when i first

01:20:45noticed on

01:20:46ducatis

01:20:47they had these

01:20:48they switched to

01:20:50this great big

01:20:50dagger style

01:20:51sump

01:20:52so it kind of

01:20:54all combed

01:20:54down and that

01:20:55wasn't necessarily

01:20:56a windage thing

01:20:57it was a let's

01:20:58not run out of

01:20:58uh oil for the

01:21:00suction

01:21:01we don't want

01:21:02the pump

01:21:02pushing air

01:21:03hard acceleration

01:21:05or let's do a

01:21:06wheelie for a

01:21:06quarter mile

01:21:07and yeah

01:21:08i understand

01:21:10from some

01:21:10internal lore

01:21:11that when the

01:21:12uh um the

01:21:13soft tail was

01:21:14being tested

01:21:15the new soft

01:21:16tail that

01:21:16replaced the

01:21:17dyna

01:21:17that they you

01:21:18know they made

01:21:19the single cruiser

01:21:20line and got

01:21:20rid of the

01:21:20dyna in the

01:21:21lineup

01:21:22uh there were

01:21:23the dyna folks

01:21:24who were the

01:21:25high performance

01:21:26guys the stunt

01:21:26dudes and always

01:21:27doing the wheelies

01:21:28like you're not

01:21:29you don't see

01:21:31too many fat

01:21:31boys out there

01:21:32doing you know

01:21:33big smoky

01:21:34burnouts and

01:21:34huge wheelies

01:21:35and so they

01:21:36uh apparently

01:21:37tested with some

01:21:38of the dyna guys

01:21:39and kind of let

01:21:39them have at it

01:21:40with the soft

01:21:41tail to make

01:21:41sure it

01:21:42wouldn't run

01:21:42out of oil

01:21:43while they were

01:21:44wheelie

01:21:44pretty cool stuff

01:21:46yeah

01:21:47oh the internal

01:21:49life of the

01:21:50engine or the

01:21:52transition you

01:21:53know i look

01:21:53back at at all

01:21:54my time working

01:21:55on things and i

01:21:55had a triumph

01:21:56tier six car my

01:21:57first car and

01:21:58i was doing

01:21:59some transmission

01:21:59work and i i

01:22:02thought you know

01:22:03what before i put

01:22:04the cover on i'd

01:22:05like to see this

01:22:06thing run with the

01:22:08top cover off and

01:22:09see what happens

01:22:09and it was it was

01:22:12great you can take

01:22:13off the tunnel in a

01:22:14triumph tier six the

01:22:15factory was this sad

01:22:16piece of cardboard

01:22:17that always got oil

01:22:18soaked and destroyed

01:22:19i fiberglassed mine

01:22:20and helped it out and

01:22:22improved the seal and

01:22:23i felt less light

01:22:23headed while i was

01:22:24driving which was

01:22:25great and um

01:22:27i took the cover

01:22:29off because that's

01:22:29how you get the

01:22:30trans out you can

01:22:31take it out through

01:22:32the interior take

01:22:33out the seats so

01:22:34you can see the

01:22:34whole thing i

01:22:35bolted it in i'm

01:22:37ready to go it's

01:22:37hooked up to the

01:22:38rear wheels it's on

01:22:39four jack stands and

01:22:41i'm like i'm gonna

01:22:42wrap this sucker with

01:22:44uh plastic wrap and

01:22:46i'm gonna put it in

01:22:46gear and i'm gonna

01:22:48run it and see what

01:22:49happens i'm like i'll

01:22:51put it in fourth gear

01:22:52because that'll make

01:22:53things spin around

01:22:54you know like the

01:22:54output's gonna be

01:22:55high and so i

01:22:57clicked the selector

01:22:58by hand because the

01:23:00forks were off because

01:23:00the top has the

01:23:01forks and i moved the

01:23:02selector to fourth i

01:23:04think this was fourth

01:23:05gear and um i let the

01:23:09clutch out and i was

01:23:11like oh wow it was

01:23:12very vigorous even at

01:23:14low rpm and then i

01:23:15went in fourth gear and

01:23:18i revved it up to like

01:23:182500 or 3000 which

01:23:20should be 60 miles

01:23:22per hour and i could

01:23:24not believe the

01:23:26agitation of the oil

01:23:27inside the gearbox i'm

01:23:28like well that's why

01:23:29this thing doesn't have

01:23:30an oil pump some

01:23:31gear boxes do have

01:23:32oil pumps and

01:23:33efficiently now we're

01:23:34not letting splash

01:23:35lubrication take care

01:23:37of of a lot of

01:23:38different gear trains

01:23:39we're putting drips

01:23:40sprays of oil into the

01:23:42gear train that's just

01:23:44enough to do the job

01:23:45and an engineer named

01:23:46hatha uh joined

01:23:48yamaha in like 61

01:23:50um and he brought

01:23:53that idea into uh

01:23:55service that there

01:23:57would be a an oil

01:23:59gallery with little

01:24:01drillings one oil jet

01:24:03for each gear pair

01:24:04nice no more gears

01:24:08dipping into oil they

01:24:09don't dip they whip

01:24:11as mark just noted when

01:24:15the engine is running the

01:24:17inside of the gearbox is

01:24:18a violent oil storm

01:24:20this is the last thing

01:24:22you want for efficiency

01:24:23is tons of oil going

01:24:24through the mesh

01:24:25because it's having to

01:24:27be pumped out of there

01:24:28at tremendous speed

01:24:30squeezed out from those

01:24:32shapes that are coming

01:24:35together on oil so

01:24:37that's why it is better

01:24:39to have an individual

01:24:41quite small jet for

01:24:43each mesh and you'll

01:24:44find that on all race

01:24:45engines now yeah

01:24:47there's also the spray

01:24:48bar on some uh cam

01:24:49shafts i think that's

01:24:50mostly a american v8

01:24:52thing or actually i

01:24:54think a lot of the

01:24:55older uh

01:24:55other guys running the

01:24:58four-cylinder you know

01:25:00cross-flow cortinas and

01:25:02stuff like that where you

01:25:03or overhead cam they put a

01:25:04little spray bar that

01:25:05drips oil on the lobe

01:25:06itself to make sure that

01:25:08we are adequately covered

01:25:09well in the honda cbr that

01:25:11uh we made that video

01:25:13those videos with the

01:25:15cams are hollow and

01:25:16they're full of oil and

01:25:18each lobe um has an oil

01:25:21jet drilled in the lobe so

01:25:23that as the thing is

01:25:25starting to begin the lift

01:25:26process first it lubricates

01:25:29then it lifts the valve

01:25:30good one

01:25:32i could talk about the

01:25:35inside of an engine

01:25:36forever kevin

01:25:37well that's what we've

01:25:38done that's just what

01:25:41we've done

01:25:41yep

01:25:42so um stuff to think

01:25:46about

01:25:46yeah but imagine if we

01:25:49got everything perfect

01:25:50how fast and efficient we

01:25:52might be

01:25:52holy toledo

01:25:53yeah 350 miles an hour on

01:25:56the freeway going to work

01:25:57getting a million miles per

01:25:59gallon

01:25:59we don't have the tires we

01:26:01don't have the chain we

01:26:02don't have the stability

01:26:03but we can conceive of it

01:26:06yep well we keep

01:26:07striving that's what it

01:26:08is yes it is striving you

01:26:10know you know you got to

01:26:11keep learning and as you

01:26:13always say be your own

01:26:14expert

01:26:15just keep thinking about

01:26:17it

01:26:17yeah what else are you

01:26:18going to do at four o

01:26:19o'clock worry about the

01:26:20future nah

01:26:21if you don't know

01:26:22anything you don't have

01:26:23anything to think about

01:26:24yeah

01:26:24oh gracious

01:26:25can't have that

01:26:27yeah

01:26:28well thanks for listening

01:26:30folks that's it for now

01:26:31we'll catch you next time

01:26:33see in the comments

01:26:34tell us what to talk about
