00:00No problems, no issues, a little bit of painting peeling because someone didn't
00:04prep it when they powder coated it and then we got a nice little chip right
00:07there. At the beginning of the week that chip was not there, then it appeared and
00:11now it's growing and then we got a chip. Welcome to Sam's Garage presented by NH
00:17Oil Undercoding.
00:30This week on Sam's Garage, the great race rolls through the mountains of West
00:54Virginia as teams tackle winding roads, vintage engines, and small-town hospitality.
01:00We'll meet the racers, the artists, and even a 15-year-old driver chasing his
01:06dream. Then we head to Southfield Classics to talk EV manufacturing and the future
01:13of high-voltage builds. Finally, Sam breaks down the science of boost, turbochargers,
01:21wastegates, and blow-off valves made simple.
01:30We have 135 plus cars in the great race. Checkpoints along the way that they don't
01:36know in advance and so the goal is you're going to stay on target. From start to finish,
01:41it's like family to me. Keeping it maintained, keeping it running hard, it's a complete family
01:46member. It's an experience. All the workers, all the towns that have been welcoming us.
01:50Winning an ace in the great race is just, it's one of the things that just lifts you up.
01:54Were we on time and everybody else was wrong? Were they on time and we were wrong? I guess
01:58we'll find out tonight. 135 vintage cars, endless hills, and hometown pride, this leg of the great
02:08race runs through the scenic roads of West Virginia. We just left a very scenic area back in Charleston.
02:21We went through the New River Gorge Bridge, which is the tallest arch bridge in the North America,
02:25built in 1977. Right now we're in Lewisburg, which is considered the coolest small town in USA. And
02:31from the looks of it, the Nissan made it. We just went through some treacherous back roads, but it
02:36was absolutely a blast. We've got a small little chip right here on the windshield that's growing a
02:41little bit, so we have to watch out for that. It's a 1938 Chevy. It's all original other than the
02:50interior. My wife actually sewed the interior together for us. Mechanically, it's been gone
02:57through, but it's still all the original parts and pieces. 80 horsepower, 216 cubic inch, inline six,
03:05second gear only up hills, and top speed of 35. This area is pretty challenging to get up and down
03:11through those hills. Oh, we got Theron Navigator today and then my buddy Finn. Finn's in the backseat,
03:16just chilling, having a good day. St. Louis Community College team, we got a 72 Mercury Cougar running this
03:22year and a 1941 Ford Super Deluxe. And we are team two with this car. We are in the automotive program,
03:30which is just a two-year program, just to see if you want to learn the process of becoming a technician
03:35and working on cars. And a lot of us are working in shops back in St. Louis, so we love it. My dad,
03:41a couple of years ago, bought a VW Bug 68 and I've just been messing with that for a couple of years
03:46with him. So, family tradition. The great race experience is, it's great. Just going around the
03:50country, seeing things I've never seen before in states I've never been to and dealing with my
03:55buddies from school is probably the greatest experience I've had.
04:02People are discovering it and are surprised and they're moving here from other states because of the
04:09quality of life and the cultural events. And they can buy twice the house that they had in these
04:16urban areas for the same amount of money or even less. We have boutiques and shops also. We're about
04:2210 minutes from the world famous Greenbrier Resort Hotel.
04:30For the third year in a row, we were named the first 10 best USA Today's 10 best small town food scene.
04:36And so we own this visitor center here that's right in downtown Lewisburg. And we're just so happy to host
04:43this event. We're providing lunch for all the racers and volunteers. And it's just great to have this
04:50hubbub of all of the excitement and these great cars and all of these great people in our town. It's been
04:56a real pleasure. Our goal and mission is to market the area as a premier tourist destination. So people will
05:03come here and, you know, spend the night, go eat in our restaurants, shop in our shops, float down the
05:09beautiful Greenbrier River and just enjoy our area. So we're, we're like the marketing agency and the
05:15cheerleader for the Greenbrier Valley. Oh, I'd be navigator, hands down. Navigator, driver, easy.
05:21Yeah. My direction style is kind of like naming, say like the funky looking tree or, you know,
05:30you're going to see a turn, but you got past that one, head to the next one. All the landmark stuff.
05:34It's not great. I've learned to roll with it. Farewell from Lewisburg.
05:39Sam's Garage is presented by NHOU. Brought to you by the following companies.
06:09Welcome back to Sam's Garage presented by NH Oil Undercoding.
06:33From Evel Knievel's artist to 15 year old driver with his family team,
06:37the great race brings generations together. Proof that passion for cars has no age limit.
06:44The great race is brought to you by Rod In Supply. We don't just sell them, we race them.
06:51So first of all, none of this would be possible without our sponsors. Rogo Fasteners, Hemsaw,
06:55ACC Performance, Rod In Supply. At 30 miles an hour in a stick shift, you can be in second or third gear.
07:01Both are hard. Neither gear works for you best. So it was so hard keeping 30 miles an hour in that gear
07:07Doug was laughing at me so hard. So the great race is all about challenges, my friends. It is not easy.
07:12You're going slow, but there is nothing easy about it at all. Let me go and see if I can't put this
07:17guy on nice and straight on this race car. We call it Datsun. Belongs to Doug Harris.
07:22Hopefully be friends till the end of our days. In fact, I have a couple friends who every year try to
07:32make it to either the start or the finish to spend about three or four days with us. And along the way,
07:39we're fortunate this year to get to Darrell's hometown, a home area in West Virginia, so he could
07:46see some relatives and longtime friends. And today, of course, his siblings are here to
07:51greet him in Roanoke. And what a better way to finish than to see your family.
07:56My sister and niece and nephew live here in Roanoke. My brother is down from Wheeling,
08:01West Virginia. And my other sister is up from your neck of the woods, Atlanta, Georgia. We're having
08:07a family reunion at The Great Race. The Great Race is filled with special people like George
08:13Satellite. This gentleman is the artist that did all the work on Evel Knievel's motorcycle and helmet.
08:18He's also the artist behind the artwork that's going to be auctioned off at the banquet the last day.
08:22And all the proceeds from the auction goes towards the X-Cup. Tell us about your painting, George.
08:27Basically, I took different vehicles that I knew were going to be in the race,
08:32except for this one. This one here won three years ago. And it's a Velie and actually was made in my
08:39hometown in the 20s. And this car here won about three years ago. And a couple years ago,
08:47these young ladies were only 18 and 19 when they did it. And loving Corvettes, they put the Corvette in,
08:52it's in this race. And these guys with this 41 or 40 Ford. And then these are the young kids in the X-Cup
09:00that have got this 76 Toronado. I call it the Hooptie. They got it all fixed up and they're driving,
09:07having a lot of fun. This Hooptie right here with the bullhorns on it, this is the one that Cotton
09:11and I fixed in the parking lot for the X-Cup. And the very next day, the kids got an A. So we did a
09:16good job fixing that.
09:20Casey's right next to me. I look at him like, man, how old are you? He's like, I'm 15 years old.
09:25I'm like, and you're driving the car? He goes, yes. I'm like, you're driving it with a permit, right?
09:28He said, yes. And he's got his family, his cousin, his grandpa, and the father with him.
09:33Now for all you guys who are waiting until you're 18, 20, 21, 22 to get your licenses,
09:37I'm sorry, but shame on you. This guy has got a permit and he's doing the great race. And in my
09:41opinion, the Navigator's got a hard job, but we have a very difficult job, don't we?
09:46So I've been racing since I was three. I started out in USAT quarter midgets and
09:53I went desert racing after that, did that for a couple of years. And now I'm back doing circle
09:58track and IMCA modifieds. Wow. So what's the future look like for him? To whatever we can get
10:04his feet in, right? Yes. One of the things I always wanted to do is just get him in whatever
10:08cars we can get him in to race and have a good time. And, and my dad has been a big help to me and
10:14in accomplishing that, you know? Well, it's a 1963 Ford Galaxy 500. It's a convertible. I bought
10:21it in Massachusetts about four years ago. I asked the boys if they wanted to race, they were all over it.
10:27A little ace over here was ready to do the video for us for a family event.
10:41I've been driving this Southfield Classics SC31T all weekend. This is the prototype they built.
10:47Complete Chevy 3100. The patina on it is absolutely real. This truck is as you see it from the factory.
10:55All they did was use this as a mule to make it high voltage. And you guys, these high voltage
11:00vehicles don't have the issues that any of these EVs have. One, they're not ugly. For some reason,
11:04the companies think that you have to make the cars design a certain way so that you know that it's
11:09electric and most of them are just ugly. They're heavy. And because they're heavy, they may have a
11:14lot of road noise. And that road noise also is the reason why you're killing your tires because the tires
11:19have to put up with more weight. So these trucks that Southfield is building along with the GT doesn't
11:25have any of those issues. This truck weighs exactly the same as a regular 3100 Chevy truck would.
11:30The powertrain has been replaced with high voltage powertrain and the three batteries
11:34are the same weight as a complete outfitted 350 small block. So considering that this truck is a 1950
11:4051 truck five window and driving it down the road has none of the noises that my Chevy Hemi truck has.
11:45This thing is completely quiet and solid. It's very cool. Welcome back to more Sam's Garage presented by NHOU.
12:09At Southfield Classics, Noah and Dan show what it takes to build electric EV hot rods.
12:15Where craftsmanship meets cutting edge technology and six month turnaround times.
12:24This week at Southfield Classics, we're going to be talking education. There's a lot of things that
12:27people don't know when it comes to high voltage vehicles. And Noah and Dan are going to answer
12:32a lot of those questions today. Where do you see the future of high voltage going? Well, a lot of it's
12:37going to obviously change in technology, right? So eventually your battery packs will be smaller.
12:43All this stuff will be more obtainable. And then you'll have more suppliers for these things to
12:47where it will almost not make sense to even go the other direction where typically most people go,
12:51which is a gasoline engine. And it's eventually will be enough to a point where I think everybody
12:57will be satisfied. When? How long? That is, I guess, the question that would be hard to answer,
13:03but it'll make it there, right? There's plenty of people working on it now.
13:06So you're saying that eventually the high voltage stuff is going to be maybe not so scary.
13:12You know, even on the green truck was actually even a lot faster than what I assumed it to be.
13:17But what becomes the harder part of it is probably the software to ensure that everything's working
13:23properly. And safely. And safely is very important, right? Very important. A lot of what we do here is to
13:29ensure that the cabling and even some of the wiring is done efficiently enough to where it's not coming
13:36back. And it's all just, it's all really just a plug issue. It's really just maybe one little
13:41connector. That's it. In most cases. Yep. That's what it seems to be. Like you said, with the vehicles,
13:46you have a lot less maintenance. And that's because the only thing that you have as far as the cooling
13:50system is for the inverter. And then you've got the standard brake system. Yeah. You just have a
13:55rotating electric motor that just gets cooled and lubricated by a trans fluid. All right. So Dan,
14:00what does it take to actually be a manufacturer? So it's, it's a real, uh, real pain. Let's put it
14:07that way. But in order to be a manufacturer, the jump from being a hot rod builder and going to
14:11manufacturing, it's just a long process. So part of the manufacturing process would be a licensed VIN
14:17manufacturer because we have to get all the certifications together, uh, in order to provide
14:22VIN numbers for the vehicles. So our trucks are considered 2025, 26 model year vehicles,
14:27just like any other new car, because they're all new parts. There's a couple of things that we had
14:32to follow. One of them is the replica car law. In order to get a VIN in the United States now,
14:37according to the EPA and NHTSA, is you, you won't be able to do it with an ICE engine. Ice being internal
14:43combustion engine. In order for us to get our licensing, it had to be an electric vehicle. You have to go
14:48through the government process, of course, which is, you know, always a fun ordeal. And none of this is
14:53inexpensive. None of it is cheap. Let's put it that way for us to, uh, to pass all. Of course,
14:58we got to pass all the tests. We've got to have all of those in place. But of course, like I said,
15:02we're going to do low volume here. We're only doing about 10 to 15 vehicles a year. That kind of keeps
15:07us under a little bit of a radar. So where the customer wins is you and I were just talking about this
15:11earlier of the waiting lists that are going on out there with people who want vehicles built.
15:16Absolutely. And what we've seen with the business I was in before I came here,
15:21I would go all over Atlanta working at different shops. And what you see is they've got a backlog
15:26and they're putting people on waiting lists to build their cars. So a lot of people that are
15:29wanting to build a street rod or a resto mod, they're three years out, three years out, five years out.
15:34Before they even hit the shop. Before they even hit the shop. Right.
15:37The way that we've got to set up with the manufacturing side of it now is, is we can actually turn a car
15:42around one every six months. So from the time that you put your deposit down to the time you deliver
15:47the vehicle, it's going to be about a six month turn. So next week we're going to come back down
15:51to Southfield Classics and we're going to start to assemble the vehicle, show you what the process
15:54it takes to make one of these in a six month period so that you guys can have one for yourself.
16:05Sam's Garage is presented by NH Oil Undercoating.
16:09Sam's Garage is brought to you by the following companies.
16:24Welcome back to Sam's Garage presented by NHOU.
16:54Sam breaks down turbocharger basics, boost, blow off valves and wastegates explaining how to add power
17:03safely without blowing your engine. All right, so today we're going to be talking about boost.
17:09I was on the internet scrolling because that's what we all do, right? And I saw an explanation
17:15of what the job of the blow off valve is and it was just totally wrong. So I wanted to clarify some
17:22things so we're going to talk about turbochargers in particular today and boost and how it all works.
17:27The turbocharger first off is a compressor that has a turbine housing on one side and a turbine that
17:34is connected to an impeller through a common shaft. In the middle is a cartridge that oil goes in and oil
17:41comes out and basically the theory behind it is right here you have an exhaust manifold and this is
17:47a super manifold it takes the six cylinders and brings them collectively into one area which is
17:53the turbo flange and then you have the wastegate flange. The turbocharger is going to sit right here
17:57the gases are going to go through spin the turbine which in turn spins the impeller which compresses the
18:04air and creates heat. When you create the heat it's going to go through the intercooler and this is
18:09basically a radiator core it's air to air intercooler it's going to cool that air charge down from
18:14whatever it is to roughly ambient temperature that's where you want it but the more space you
18:20have to fill that's where lag comes into play. This is a Subaru turbo and the wastegate which we're
18:26going to talk about right now is internal and it controls it right here through the turbine housing.
18:31So the wastegate's job right here is a valve and it's going to open up determined by boost there's a
18:37spring in here let's say you wanted eight pounds of boost there'll be an eight pound spring in here
18:42you're going to put boost pressure here to the side that's going to lift the spring up at eight psi
18:46it's going to open the valve it's going to bleed off gas energy slowing down the turbine or keeping
18:51it regulated at a certain speed. The blow off valve's job what happens is the intake manifold which takes
18:57the air charge has a throttle body and the throttle plate when it's open the boost goes right in but as
19:04soon as you snap that throttle you do this and the air stops and has nowhere to go the job of the blow off
19:10valve is to release the air and put it out into atmosphere saving the turbocharger so when it
19:17comes to boost especially turbochargers it's going to be the most efficient way that you can add boost
19:21to your engine a supercharger does the same thing except the blower is a runoff of a belt which takes
19:27parasitic loss from the crankshaft and therefore costs you horsepower so especially you four cylinder
19:32guys you six cylinder guys you don't have a lot of torque to waste but a four cylinder especially
19:37requires a turbocharger because there is no torque there to spare to turn a blower so you're not
19:42making any real power right i think it's really important too and you you've always been known for
19:47building you know efficient and for longevity and so many people if you want to put a turbo on your car
19:54don't just call one person don't just go to one source on the internet you you're going to need to
19:59ask around and make sure that you're not just trying to get the most you can possibly fit into because
20:04that you're just going to blow it up not only that you don't want to buy an inexpensive turbo
20:08either because if it falls apart it goes through the engine it can cause a lot of problems do your
20:13research on this one absolutely so you guys go out there have some fun you kids this is nothing
20:19more fun than taking one of these turbochargers right here a little bitty add some air eight pounds
20:24of boost if done right any engine can handle eight pounds of boost all day long so grab yourself a little
20:29car four cylinder go out there and do what we did with what we did the beginning of nopi and build a cool
20:34car and if you have questions if you're building a car especially with a turbo and and you're not
20:41positive send sam an email at info samsgaragetv.com
