00:00They powder coated it and then we got a nice little chip right there at the
00:03beginning of the week that chip was not there then it appeared and now it's
00:07growing and then we got a chip. Welcome to Sam's Garage presented by NH Oil
00:12undercoating.
00:30This week on Sam's Garage, the great race rolls through the mountains of West
00:49Virginia as teams tackle winding roads, vintage engines, and small-town hospitality.
00:56We'll meet the racers, the artists, and even a 15-year-old driver chasing his
01:01dream. Then we head to Southfield Classics to talk EV manufacturing and the future
01:08of high-voltage builds. Finally Sam breaks down the science of boost, turbochargers,
01:16wastegates, and blow-off valves made simple.
01:21We have 135 plus cars in the great race. Checkpoints along the way that they don't
01:31know in advance and so the goal is you're going to stay on target. From start to finish,
01:35it's like family to me. Keeping it maintained, keeping it running hard, it's a complete
01:40family member, it's an experience. All the workers, all the towns that have been
01:44welcoming us. Winning an ace in the great race is just it's one of the things that
01:48just lifts you up. Were we on time and everybody else
01:51was wrong? Were they on time and we were wrong? I guess we'll find out tonight.
01:58135 vintage cars, endless hills, and hometown pride, this leg of the great race runs through
02:04the scenic roads of West Virginia.
02:12We just left a very scenic area back in Charleston. We went through the New River Gorge Bridge,
02:18which is the tallest arch bridge in the North America, built in 1977. Right now we're in
02:23Lewisburg, which is considered the coolest small town in USA. And from the looks of it,
02:27the Nissan made it. We just went through some treacherous back roads, but it was absolutely
02:32a blast. We've got a small little chip right here on the windshield that's growing a little
02:36bit, so we have to watch out for that. It's a 1938 Chevy. It's all original, other than
02:45the interior. My wife actually sewed the interior together for us. Mechanically, it's been gone
02:52through, but it's still all the original parts and pieces. 80 horsepower, 216 cubic inch, inline
02:59six, second gear only up hills, and top speed of 35. This area is pretty challenging to get up and
03:06down through those hills. Oh, we got Teron Navigator today, and then my buddy Finn. Finn's in the
03:11backseat, just chilling, having a good day. St. Louis Community College team, we got a 72 Mercury
03:16Cougar running this year, and a 1941 Ford Super Deluxe. And we are team two with this car. We are in
03:23the automotive program, which is just a two-year program, just to see if you want to learn the
03:29process of becoming a technician and working on cars. And a lot of us are working in shops back in St.
03:34Louis, so we love it. My dad, a couple of years ago, bought a VW Bug 68, and I've just been messing
03:40with that for a couple of years with him, so family tradition. The great race experience is, it's great,
03:45just going around the country, seeing things I've never seen before, in states I've never been to,
03:49and dealing with my buddies from school is probably the greatest experience I've had.
03:53People are discovering it, and are surprised, and they're moving here from other states,
04:03because of the quality of life, and the cultural events, and they can buy twice the house that they had
04:11in these urban areas, for the same amount of money, or even less. We have boutiques and shops. Also, we're
04:16about 10 minutes from the world-famous Greenbrier Resort Hotel.
04:19For the third year in a row, we were named the first 10 best USA Today's 10 best small town food scene. And so we,
04:32own this visitor center here, that's right in downtown Lewisburg, and we're just so happy to host this event.
04:39We're providing lunch for all the racers and volunteers, and it's just great to have this hubbub of all of the
04:46excitement, and these great cars, and all of these great people in our town. It's been a real pleasure.
04:52Our goal and mission is to market the area as a premier tourist destination, so people will come here and, you know,
04:59spend the night, go eat in our restaurants, shop in our shops, float down the beautiful Greenbrier River, and just enjoy our area.
05:07So we're, we're like the marketing agency and the cheerleader for the Greenbrier Valley.
05:12Oh, I'd be navigator, hands down.
05:14Navigator, driver, easy.
05:16Yup.
05:17Yeah.
05:18My direction style is kind of like naming, say like the funky looking tree, or, you know, you're gonna see a turn, but you got past that one, head to the next one.
05:28All the landmark stuff.
05:29It's not great.
05:30I've learned to roll with it.
05:32Yup.
05:33Farewell from Lewisburg.
05:35Sam's Garage is presented by NHOU.
05:45Brought to you by the following companies.
06:05Welcome back to Sam's Garage, presented by NH Oil Undercoding.
06:20From Evel Knievel's artist to 15-year-old driver with his family team, the great race brings generations together.
06:34Proof that passion for cars has no age limit.
06:38The great race is brought to you by Rod In Supply.
06:42We don't just sell them, we race them.
06:45So first of all, none of this would be possible without our sponsors.
06:48Rogo Fasteners, Hemsaw, ACC Performance, Rod In Supply.
06:52At 30 miles an hour in a stick shift, you can be in second or third gear.
06:55Both are hard.
06:56Neither gear works for you best.
06:58So it was so hard keeping 30 miles an hour in that gear.
07:01Doug was laughing at me so hard.
07:03So the great race is all about challenges, my friends.
07:05It is not easy.
07:06You're going slow, but there is nothing easy about it at all.
07:10Let me go ahead and see if I can't put this guy on nice and straight on this race car.
07:14We call it Datsun.
07:15It belongs to Doug Harris.
07:16Hopefully be friends till the end of our days.
07:25In fact, I have a couple friends who every year try to make it to either the start or the finish to spend about three or four days with us.
07:31And along the way, we're fortunate this year to get to Darrell's hometown, a home area in West Virginia, so he could see some relatives and longtime friends.
07:43And today, of course, his siblings are here to greet him in Roanoke.
07:47And what a better way to finish than to see your family.
07:50My sister and niece and nephew live here in Roanoke.
07:54My brother is down from Wheeling, West Virginia.
07:56And my other sister is up from your neck of the woods, Atlanta, Georgia.
08:01We're having a family reunion at The Great Race.
08:04The Great Race is filled with special people like George Sadlake.
08:08This gentleman is the artist that did all the work on Evel Knievel's motorcycle and helmet.
08:12He's also the artist behind the artwork that's going to be auctioned off at the banquet the last day.
08:17And all the proceeds from the auction goes towards the X-Cup.
08:20Tell us about your painting, George.
08:22Basically, I took different vehicles that I knew were going to be in the race, except for this one.
08:28This one here won three years ago.
08:31And it's a Velie, and actually it was made in my hometown in the 20s.
08:36And this car here won about three years ago.
08:40And a couple years ago, these young ladies were only 18 and 19 when they did it.
08:45And loving Corvettes, they put the Corvette in.
08:47It's in this race.
08:48And these guys with this 41 or 40 Ford.
08:51And then these are the young kids in the X-Cup that got this 76 Toronado.
08:58I call it the Hooptie.
08:59They got it all fixed up, and they're driving and having a lot of fun.
09:02This Hooptie right here with the bullhorns on it, this is the one that Cotton and I fixed in the parking lot for the X-Cup.
09:08And the very next day, the kids got an A, so we did a good job fixing that.
09:15Cason's right next to me.
09:16I look at him like, man, how old are you?
09:18He's like, I'm 15 years old.
09:19I'm like, and you're driving the car?
09:21He goes, yes.
09:22I'm like, you're driving it with a permit, right?
09:23He said, yes.
09:24And he's got his family, his cousin, his grandpa, and the father with him.
09:27Now, for all you guys who are waiting until you're 18, 20, 21, 22 to get your licenses, I'm sorry, but shame on you.
09:33This guy has got a permit, and he's doing the great race.
09:36And in my opinion, the Navigator's got a hard job, but we have a very difficult job, don't we?
09:40So I've been racing since I was three.
09:43I started out in USAC Quarter Midgets, and I went desert racing after that, did that for a couple of years.
09:51And now I'm back doing circle track and IMCA Modifieds.
09:55Wow.
09:56So what's the future look like for him?
09:58To whatever we can get his feet in, right?
10:00Yes.
10:01One of the things I always wanted to do is just get him in whatever cars we can get him in to race and have a good time.
10:06And my dad has been a big help to me in accomplishing that, you know?
10:11Well, it's a 1963 Ford Galaxy 500.
10:14It's a convertible.
10:15I bought it in Massachusetts about four years ago.
10:18I asked the boys if they wanted to race.
10:20They were all over it.
10:21A little Ace over here was ready to do the video for us for a family event.
10:36I've been driving this Southfield Classics SC31T all weekend.
10:40This is the prototype that they built.
10:42Complete Chevy 3100.
10:44The patina on it is absolutely real.
10:47This truck is, as you see it from the factory, all they did was use this as a mule to make it high voltage.
10:53And you guys, these high voltage vehicles don't have the issues that any of these EVs have.
10:57One, they're not ugly.
10:58For some reason, the companies think that you have to make the cars design a certain way so that you know that it's electric and most of them are just ugly.
11:05They're heavy.
11:06And because they're heavy, they may have a lot of road noise.
11:09And that road noise also is the reason why you're killing your tires because the tires have to put up with more weight.
11:15So these trucks that Southfield is building along with the GT doesn't have any of those issues.
11:20This truck weighs exactly the same as a regular 3100 Chevy truck would.
11:24The powertrain has been replaced with high voltage powertrain and the three batteries are the same weight as a complete outfitted 350 small block.
11:32So considering that this truck is a 1950-51 truck five window and driving it down the road has none of the noises that my Chevy Hemi truck has.
11:39This thing is completely quiet and solid.
11:41It's very cool.
11:42Welcome back to more Sam's Garage presented by NHOU.
11:49At Southfield Classics, Noah and Dan show what it takes to build electric EV hot rods.
12:10Where craftsmanship meets cutting edge technology and six month turnaround times.
12:18This week at Southfield Classics, we're going to be talking education.
12:21There's a lot of things that people don't know when it comes to high voltage vehicles.
12:24And Noah and Dan are going to answer a lot of those questions today.
12:28Where do you see the future of high voltage going?
12:31Well, a lot of it's going to obviously change in technology, right?
12:34So eventually your battery packs will be smaller.
12:37All this stuff will be more obtainable.
12:39And then you'll have more suppliers for these things to where it'll almost not make sense to even go the other direction where typically most people go, which is a gasoline engine.
12:48And it's eventually will be enough to a point where I think everybody will be satisfied.
12:53When? How long? That is, I guess, the question that would be hard to answer, but it'll make it there, right?
12:59There's plenty of people working on it now.
13:01So you're saying that eventually the high voltage stuff is going to be maybe not so scary.
13:07You know, even on the green truck was actually even a lot faster than what I assumed it to be.
13:12But what becomes the harder part of it is probably the software to ensure that everything's working properly.
13:18And safely.
13:19And safely is very important, right? Very important.
13:22A lot of what we do here is to ensure that the cabling and even some of the wiring is done efficiently enough to where it's not coming back.
13:31And it's all just, it's all really just a plug issue.
13:34It's really just maybe one little connector.
13:36That's it.
13:37In most cases.
13:38Yep.
13:39That's what it seems to be.
13:40Like you said, with the vehicles, you have a lot less maintenance.
13:42And that's because the only thing that you have as far as a cooling system is for the inverter.
13:46And then you've got the standard brake system.
13:48Yeah.
13:49You just have a rotating electric motor that just gets cooled and lubricated by a trans fluid.
13:54Alright, so Dan, what does it take to actually be a manufacturer?
13:57So it's a real pain, let's put it that way.
14:02But in order to be a manufacturer, the jump from being a hot rod builder and going to manufacturing is just a long process.
14:08So part of the manufacturing process would be a licensed VIN manufacturer because we have to get all the certifications together in order to provide VIN numbers for the vehicles.
14:18So our trucks are considered 2025-26 model year vehicles just like any other new car because they're all new parts.
14:25There's a couple things that we had to follow.
14:28One of them is the replica car law.
14:30In order to get a VIN in the United States now, according to the EPA and NHTSA, is you won't be able to do it with an ICE engine.
14:37ICE being internal combustion engine.
14:39In order for us to get our licensing, it had to be an electric vehicle.
14:42You have to go through the government process, of course, which is, you know, always a fun ordeal.
14:46And none of this is inexpensive.
14:48None of it is cheap, let's put it that way.
14:50For us to pass all, of course, we've got to pass all the tests.
14:54We've got to have all of those in place.
14:56But, of course, like I said, we're going to do low volume here.
14:58We're only doing about 10 to 15 vehicles a year.
15:01That kind of keeps us under a little bit of a radar.
15:03So, where the customer wins is, you and I were just talking about this earlier, of the waiting lists that are going on out there with people who want vehicles built.
15:11Absolutely.
15:12What we've seen with the business I was in before I came here, I would go all over Atlanta working at different shops.
15:18And what you see is they've got a backlog and they're putting people on waiting lists to build their cars.
15:23So, a lot of people that are wanting to build a street rod or a resto mod, they're three years out, three years out, five years out.
15:29Before they even get the shop.
15:30Before they even hit the shop.
15:31Right.
15:32The way that we've got it set up with the manufacturing side of it now is we can actually turn a car around one every six months.
15:39So, from the time that you put your deposit down to the time you deliver the vehicle, it's going to be about a six-month turn.
15:44So, next week we're going to come back down to Southfield Classics and we're going to start to assemble the vehicle to show you what the process it takes to make one of these in a six-month period so that you guys can have one for yourself.
15:59Sam's Garage is presented by NH Oil Undercoating.
16:05Is brought to you by the following companies.
16:29Welcome back to Sam's Garage presented by NHOU.
16:51Sam breaks down turbocharger basics, boost, blow-off valves, and wastegates.
16:56Explaining how to add power safely without blowing your engine.
16:59All right, so today we're going to be talking about boost.
17:04I was on the internet scrolling because that's what we all do, right?
17:07And I saw an explanation of what the job of the blow-off valve is and it was just totally wrong.
17:14So, I wanted to clarify some things.
17:17So, we're going to talk about turbochargers in particular today and boost and how it all works.
17:21The turbocharger first off is a compressor that has a turbine housing on one side and a turbine that is connected to an impeller through a common shaft.
17:32In the middle is a cartridge that oil goes in and oil comes out and basically the theory behind it is right here you have an exhaust manifold.
17:40And this is a super manifold.
17:43It takes the six cylinders and brings them collectively into one area which is the turbo flange and then you have the wastegate flange.
17:50The turbocharger is going to sit right here.
17:52The gases are going to go through, spin the turbine which in turn spins the impeller which compresses the air and creates heat.
18:00When you create the heat, it's going to go through the intercooler.
18:03And this is basically a radiator core.
18:05It's air to air intercooler.
18:07It's going to cool that air charge down from whatever it is to roughly ambient temperature.
18:11That's where you want it.
18:12But, the more space you have to fill, that's where lag comes into play.
18:17This is a Subaru turbo and the wastegate which we're going to talk about right now is internal and it controls it right here through the turbine housing.
18:25So, the wastegate's job right here is a valve and it's going to open up determined by boost.
18:31There's a spring in here.
18:32Let's say you wanted eight pounds of boost.
18:34There'll be an eight pound spring in here.
18:36You're going to put boost pressure here to the side.
18:38That's going to lift the spring up at eight psi.
18:40It's going to open the valve.
18:41It's going to bleed off gas energy, slowing down the turbine or keeping it regulated at a certain speed.
18:47The blow up valve's job.
18:48What happens is the intake manifold which takes the air charge as a throttle body and a throttle plate.
18:54When it's open, the boost goes right in.
18:58But, as soon as you snap that throttle, you do this and the air stops and has nowhere to go.
19:03The job of the blow up valve is to release the air and put it out into atmosphere, saving the turbocharger.
19:09So, when it comes to boost, especially turbochargers, it's going to be the most efficient way that you can add boost to your engine.
19:16A supercharger does the same thing except the blower is run off of a belt which takes parasitic loss from the crankshaft.
19:23And, therefore, it costs you horsepower.
19:25So, especially you four-cylinder guys, you six-cylinder guys, you don't have a lot of torque to waste.
19:30But, a four-cylinder especially requires a turbocharger because there is no torque there to spare to turn a blower.
19:36So, you're not making any real power there.
19:38I think it's really important too.
19:40And, you've always been known for building, you know, efficient and for longevity.
19:46And, so many people, if you want to put a turbo on your car, don't just call one person.
19:50Don't just go to one source on the internet.
19:52You're going to need to ask around and make sure that you're not just trying to get the most you can possibly fit into.
19:59Because, you're just going to blow it up.
20:01Not only that, you don't want to buy an inexpensive turbo either because if it falls apart, it goes through the engine.
20:06It can cause a lot of problems.
20:07Do your research on this one.
20:09Absolutely.
20:10So, you guys go out there, have some fun, you kids.
20:13This is nothing more fun than taking one of these turbochargers right here.
20:16A little bitty, add some air, eight pounds of boost.
20:19If done right, any engine can handle eight pounds of boost all day long.
20:23So, grab yourself a little car, four-cylinder.
20:25Go out there and do what we did with what we did at the beginning of Nopi and build a cool car.
20:30And, if you have questions, if you're building a car, especially with a turbo and you're not positive,
20:36send Sam an email at info at samsgaragetv.com.
