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 to 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
01:31don't know in advance and so the goal is you're gonna stay on target from start
01:35to finish it's like family to me so keeping it maintained keeping it
01:39running hard it's a complete family member it's an experience all the
01:43workers all the towns that have been welcoming us winning an ace in the great
01:46race is just it's one of the things that just lifts you up where we on time and
01:50everybody else was wrong were they on time and we were wrong I guess we'll find
01:54out tonight 135 vintage cars endless hills and hometown pride this leg of the
02:03great race runs through the scenic roads of West Virginia we just left a very
02:13scenic area back in Charleston we went through the New River Gorge Bridge which
02:18the 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
02:27it the Nissan made it we just went through some treacherous back roads but it
02:31was absolutely a blast we've got a small little chip right here on the
02:35windshield that's growing a little bit so we have to watch out for that it's a
02:411938 Chevy it's all original other than the interior my wife actually sewed the
02:48interior together for us mechanically it's been gone through but it's still
02:53all the original parts and pieces 80 horsepower 216 cubic inch inline six
03:00second gear only up hills and top speed of 35 this area is pretty challenging to
03:05get up and down through those hills oh we got Theron navigator today and then my
03:10buddies Finn Finn's in the backseat just chilling having a good day St. Louis
03:14Community College team we got a 72 Mercury Cougar running this year and a
03:181941 Ford Super Deluxe and we are team two with this car we are in the automotive
03:24program 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
03:32working in shops back in St. Louis so we love it my dad a couple years ago bought a
03:37VW Bug 68 and I've just been messing with that for a couple years with him so
03:42family tradition the great race experiences it's great just going around
03:45the country seeing things I've never seen before in states I've never been to and
03:49doing 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
04:01other states because of the quality of life and the cultural events and they
04:09can buy twice the house that they had in these urban areas for the same amount of
04:13money or even less we have boutiques and shops also we're about 10 minutes from
04:17the world-famous Greenbrier Resort Hotel
04:24for the third year in a row we were named the first ten best USA Today's ten best
04:30small-town food scene and so we own this visitor center here that's right in
04:34downtown Louisburg and we're just so happy to host this event we're providing
04:40lunch for all the racers and volunteers and it's just great to have this hubbub
04:45of all of the excitement and these great cars and all of these great people in
04:50our town it's been a real pleasure our goal and mission is to market the area as a
04:56premier tourist destination so people will come here and you know spend the
05:00night go eat in our restaurants shop in our shops float down the beautiful
05:05Greenbrier River and just enjoy our area so we're we're like the marketing agency
05:10and the cheerleader for the Greenbrier Valley
05:13oh I'd be navigator driver easy my direction style is kind of like naming say
05:22like the funky looking tree or you know you're gonna see a turn but you got past
05:27that one head to the next one all the landmark stuff it's not great I've
05:31learned to roll with it very well from Lewisburg Sam's Garage is presented by NHOU
05:45brought to you by the following companies
06:01welcome back to Sam's Garage presented by NH oil undercoating
06:21from Evel Knievel's artist to 15 year old driver with his
06:31family team the great race brings generations together proof that passion
06:35for cars has no age limit the great race is brought to you by rod in supply we
06:43don't just sell them we race them so first of all none of this would be
06:47possible without our sponsors rogo fasteners hem saw ACC performance rod in
06:52supply at 30 miles an hour in a stick shift you can be in second or third gear
06:56both are hard neither gear works for you best so it was so hard keeping 30 miles
07:01an hour in that gear Doug was laughing at me so hard so the great race is all
07:05about challenges my friends it is not easy you're going slow but there is
07:08nothing easy about it at all let me go and see if I can't put this guy on nice and
07:13straight 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
07:27do every year try to make it to either the start or the finish to spend about
07:31three or four days with us and and along the way we're fortunate this year to get
07:36to Darrell's hometown a home area in West Virginia so he could see some
07:41relatives and longtime friends and today of course his siblings are here to
07:46greet him in Roanoke and and what a better way to finish than to see your family my
07:51sister and niece and nephew live here in Roanoke my brother is down from Wheeling
07:56West Virginia and my other sister is up from your neck of the woods Atlanta
08:01Georgia we're having a family reunion that's a great race great races filled
08:07with special people like George Sadlake this gentleman is the artist that did all
08:10the work on Evel Knievel's motorcycle and helmet he's also the artist behind the
08:14artwork that's going to be auctioned off at the banquet last day and all the
08:18proceeds from the auction goes towards the X Cup tell us about your painting
08:21George basically I took a different vehicles that I knew was gonna we're
08:26gonna be in the race except for this one this one here won three years ago and
08:31it's a veeley and actually was made in my hometown in the 20s and these this car
08:38here won about three years ago and a couple years ago did these young ladies were
08:43only 18 and 19 when they did it and loving Corvettes they put the Corvette in
08:47it's in this race and these guys with this 40 41 or 40 Ford and then these are
08:52the young kids in the X Cup that got this 76 Toronado I call the Hooptie they
09:00got it all fixed up and they're driving having a lot of fun this Hooptie right
09:04here with the bullhorns on it this is the one that cotton and I fixed in the
09:07parking lot for the X Cup and the very next day the kids got an A so we did a
09:11good job fixing that
09:15Casey's right next to me I look at him like man how old are you he's like I'm
09:1915 years old I'm like and you're driving the car he goes yes I'm like you're
09:22driving it with a permit right he said yes and he's got his family his cousin his
09:26grandpa and the father with him now for all you guys who are waiting till you're
09:3018 20 21 22 to get your licenses I'm sorry but shame on you this guy has got a
09:34permit and he's doing the great race and in my opinion the navigators got a hard job but
09:39we have a very difficult job don't we so I've been racing since I was three I
09:43started out in USAT quarter midgets and I went desert racing after that did that
09:50for a couple years and now I'm back doing circle track and IMCA modifieds
09:55Wow so what's the future look like for him to whatever we can get his feet in
10:00right yes one of the things I always wanted to do is just get him in whatever
10:03cars we can get him in to race and have a good time and and my dad has been a big
10:08help to me and in accomplishing that you know well it's a 1963 Ford Galaxy 500
10:14it's a convertible I bought it in Massachusetts about four years ago I
10:19asked the boys if they wanted to race they were all over it a little ace under
10:23here was ready to do the video for us for a family of them
10:28I've been driving this Southfield Classics SC31T all weekend this is the prototype they built
10:42complete Chevy 3100 the patina on it is absolutely real this truck is as you see it from the factory
10:50all they did was use this as a mule to make it high voltage and you guys these high voltage vehicles
10:55don't have the issues that any of these EVs have one they're not ugly for some reason the companies
11:00think that you have to make the cars design a certain way so that you know that it's electric
11:04and most of them are just ugly they're heavy and because they're heavy they may have a lot of road
11:09noise and that road noise also is the reason why you're killing your tires because the tires have
11:14to put up with more weight so these trucks that Southfield's building along with the GT doesn't
11:20have any of those issues this truck weighs exactly the same as a regular 3100 Chevy truck would the
11:26power train has been replaced with high voltage power training the three batteries are the same
11:30weight as a complete outfitted 350 small block so considering that this truck is a 1950 51 truck
11:36five window and driving it down the road has none of the noises that my Chevy Hemi truck has this
11:41thing is completely quiet and solid it's very cool welcome back to more Sam's Garage presented by NHOU
11:50at Southfield classics Noah and Dan show what it takes to build electric EV hot rods
12:10this week at Southfield classics we're going to be talking education there's a lot of things that
12:22people don't know when it comes to high voltage vehicles and Noah and Dan are going to answer a
12:27lot of those questions today where do you see the future of high voltage going well a lot of it's
12:32gonna obviously change in technology right so eventually your battery packs will be smaller
12:37all this stuff will be more obtainable and then you'll have more suppliers for these things to
12:42where it'll almost not make sense to even go the other direction where typically most people go which
12:47is a gasoline engine and it's eventually will be enough to a point where I think everybody will
12:53be satisfied when how long that that is I guess the question that would be hard to answer but it'll make
12:59it there right there's plenty of people working on it now so you're saying that eventually the high
13:04voltage stuff is gonna be maybe not so scary you know even on the green truck was actually even a lot
13:10faster than what I assumed it to be but what becomes the the harder part of it is probably the software
13:16to ensure that everything's working properly and safely and safely is very important right very
13:22important a lot of what we do here is to ensure that the cabling and even some of the wiring is done
13:27efficiently enough to where it's not coming back and it's all just it's all really just a plug issue
13:34it's really just maybe one little connector that's it in most cases yeah that's what it seems to be with
13:39like you said with the vehicles you have a lot less maintenance and that's because the only thing
13:44that you have as far as a cooling system is for the inverter and then you got the standard brake system
13:48yeah you just have a rotating electric motor that just gets cooled and lubricated by a trans fluid
13:53all right so Dan what does it take to actually be a manufacturer so it's it's a real real pain let's
14:02put it that way but in order to be a manufacturer the jump from being a hot rod builder and going to
14:06manufacturing it's just a long process so part of the manufacturing process be a licensed VIN
14:12manufacturer because we have to get all the certifications together in order to provide
14:17VIN numbers for the vehicles so our trucks are considered 2025 26 model year vehicles just like any other
14:23new car because they're all new parts there's a couple things that we had to follow it's one of
14:29them is the replica car law in order to get a van in the United States now according to the EPA and NHTSA
14:34is you you won't be able to do it with an ice engine ice being internal combustion engine in order
14:39for us to get our licensing and it had to be an electric vehicle you have to go through the government
14:43process of course which is you know always a fun ordeal and none of this is inexpensive none of it is cheap
14:50let's put it that way for us to to pass all of course we got to pass all the tests we got to have
14:55all of those in place but of course like I said we're gonna do low volume here we're only doing
14:59about 10 to 15 vehicles a year that kind of keeps us under a little bit of a radar so where the
15:04customer wins is you and I were just talking about this earlier of the waiting lists that are going on out
15:09there with people who want vehicles built absolutely what we've seen what with the business I was in
15:15before I came here I would go all over Atlanta working at different shops and what you see is
15:19they've got a backlog and they're putting people on waiting lists to build their cars so a lot of
15:24people that are wanting to build a street rod or a resto mod or third three years out three years out
15:29five years out before they even hit the shop right the way that we've got to set up with the
15:33manufacturing side of it now is is we can actually turn a car around one every six months so from the
15:40time that you put your deposit down to the time you deliver the vehicle it's gonna be about a six
15:44month turn so next week we're going to come back down to Southfield Classics and we're going to
15:47start to assemble the vehicle to show you what the process it takes to make one of these in a six
15:51month period so that you guys can have one for yourself
15:54Sam's Garage is presented by NH Oil Undercoding is brought to you by the following companies
16:07welcome back to Sam's Garage presented by NHOU
16:35Sam breaks down turbocharger basics boost blow-off valves and wastegates explaining how to add power
16:58safely without blowing your engine all right so today we're going to be talking about boost I was on the
17:05internet scrolling because that's what we all do right and I saw an explanation of what the job of
17:11the blow-off valve is and it was just totally wrong so I wanted to clarify some things so we're going to
17:18talk about turbochargers in particular today and boost and how it all works the turbocharger first off
17:24is a compressor that has a turbine housing on one side and a turbine that is connected to an impeller
17:31through a common shaft in the middle is a cartridge that oil goes in and oil comes out and basically
17:37the theory behind it is right here you have an exhaust manifold and this is a super manifold it takes
17:44the six cylinders and brings them collectively into one area which is the turbo flange and then you have
17:49the wastegate flange the turbocharger is going to sit right here the gases are going to go through spin the
17:55turbine which in turn spins the impeller which compresses the air and creates heat when you
18:01create the heat it's going to go through the intercooler and this is basically a radiator core
18:06it's air-to-air intercooler it's going to cool that air charge down from whatever it is to roughly
18:11ambient temperature that's where you want it but the more space you have to fill that's where lag comes
18:18into play this is a Subaru turbo and the wastegate which we're going to talk about right now is internal and it
18:24controls it right here through the turbine housing so the wastegate's job right here is a valve and
18:29it's going to open up determined by boost there's a spring in here let's say you wanted eight pounds
18:35of boost there'll be an eight pound spring in here you're going to put boost pressure here to the side
18:39that's going to lift the spring up at eight psi it's going to open the valve it's going to bleed off gas
18:44energy slowing down the turbine or keeping it regulated at a certain speed the blow-off valve's job what
18:49happens is the intake manifold which takes the air charge has a throttle body and the throttle plate
18:55when it's open the boost goes right in but as soon as you snap that throttle you do this and the air
19:02stops and has nowhere to go the job of the blow-off valve is to release the air and put it out into
19:08atmosphere saving the turbocharger so when it comes to boost especially turbochargers it's going to be the
19:14most efficient way that you can add boost to your engine a supercharger does the same thing except the
19:19blower is a runoff of a belt which takes parasitic loss from the crankshaft and therefore it costs you
19:25horsepower so especially you four-cylinder guys you six-cylinder guys you don't have a lot of torque
19:30to waste but a four-cylinder especially requires a turbocharger because there is no torque there to
19:35spare to turn a blower so you're not making any real power right I think it's really important too
19:40and you've always been known for building you know efficient and for longevity and so many people if
19:47you want to put a turbo on your car don't just call one person don't just go to one source on the
19:52internet you you're going to need to ask around and make sure that you're not just trying to get
19:57the most you can possibly fit into because that you're just going to blow it up not only that you
20:02don'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 do your research on this one absolutely so you guys go out there
20:11have some fun you kids this is nothing more fun than taking one of these turbochargers right here a
20:17little bitty add some air eight pounds of boost if done right any engine can handle eight pounds of
20:22boost all day long so grab yourself a little car four cylinder go out there and do what we did with
20:27what we did the beginning of Nopi and build a cool car and if you have questions if you're building a car
20:33especially with a turbo and and you're not positive send Sam an email at info at samsgaragetv.com
20:40be sure to check out sam's garage on these other media platforms
20:50from the great race to ev innovation and turbo tech this episode proves every build from antique
21:01to electric is driven by skill science and love for the road join us next time on sam's garage
21:07where every ride tells a story
