Electrical Engineer for IndyCar here. - The solid rods where the shocks go are used for towing so the real dampers aren't exposed to wear during travel. - The Yellow looking head surround should have two lever at the front that twist and allow the front to pop up, then the whole thing slides forward off of dowell pins in the tub. Will make it alot easier to get in and out. - The big hole in the top of the engine cover was for the old "pop-off" valve that the series used to scrutineer boost levels. This era car was technically part of CART that ran a turbocharged V8. The biggest "issue" you're going to have to work out is the original engine IS the torque member between the front tub and the rear suspension. There is no "chassis" that connects the front of the car to the rear. Holler if you have any other questions.
Rob dahm is the only youtuber that can repeatedly lose every race and maintain respect as a legend. That's because his builds are still untamed wild animals that ten years ago people said was impossible. Love me some rob dahm, been here since the four rotar went missing in shipping
I actually work with Richie and it's so cool seeing this car! I'm gonna see if we can get him to come comment on the vid to tell you a bit about it. He has a lot of cool ass stories from his time in Indycar
Make sure your helmet has proper aero for open-cockpit, otherwise it’ll try to pull your head off when driving at speed. A HANS device is also a good idea
@@Blackinterceptor999 What is that if you don't mind explaining it? If you don't feel like it I'll look it up, just like it better when someone explains the little things they think I should know about it instead of my uninformed arse trying to seek out the things I believe I need to know about it.. Which I have zero clue what those are lol.
Nice score! Just a heads up, those arent shocks, those are ride sticks. Teams pull the coilovers out so as to not let the cars go down the highway on the race shocks. It puts tons of extra wear on them.
For those that dont know. This car was driven (or belonged to...) by a guy called *Richie Hearn* -- this would have been his car very early on in his career. Richie drove some five cars that used the same Ford Cosworth XB/XD V8t engine with 3 different types of body chassis. This one is the Lola T97/00 Chassis - shown by the marking at 10:03 '97Lola XD' (Lola for chassis and XD for Cosworth XD Engine) so it is his 1997 car that he did most of his driving with. Richie is still alive and well and is currently a driving instructor at Spring Mountain Motorsports Ranch's Ron Fellows driving school.
@@guidoheeling1179 you sound like someone who cant lift bottle of milk without moms help. Both of them have +/- areas. Not just my dad is better than yours.
Offroad guys with monster trucks know a thing or two about putting 1200 hp or more to an input shaft that sits a foot lower tham the motor, I'm sure Bobert can figure it out
I wonder if this is the car that he won the race in Las Vegas in 1996 or drove in the 96 Indianapolis 500? It has the road course wings on it and I think it's the 1997 livery, but it was very common to use the older cars as a show car because they would be obsolete after 1-2 seasons usually. In the cockpit there should be something from Reynard with the serial number or a specific chassis number for this car. There's probably someone that worked on that team that might still have some notes with setup information and a list of all the races it entered that could be found through a CART group on Facebook. This is a great livery that's very well remembered by fans and the Reynard (I think this is a 95i) is one of the best looking IndyCar chassis of all time.
The Lola T97/00 never won a race. It was a terrible chassis. The closest it came to a win was when Adrian Fernandez got lucky on fuel strategy and got third on a street circuit.
@@MX304 Oh, I was thinking this was an older chassis. This is when Lola dominated and I think the year Newman Haas ran the Swift and there was the Penske chassis, which wasn't very good either.
This is a Lola T97. It's inscribed in the chassis on the back but you can also tell from the nose configuration. Awful car that never won a race however hothweels did make a diecast of Richie Hearns car (this car) for 1997 which is pretty cool.
@@ILSRWY4 how is it not the best? The racing was close and the speeds were high, but it wasn't completely sanitized and calculated like current open wheel racing. Late 90s cart cars also looked fuckin sweet, like a cruise missile on wheels.
@@NewfieOn2Wheels I agree the broadcasts were upbeat with that 90s flare to them, cars looked great, drivers were awesome and competitive even had the Nigel Mansell come over from F1 for a season. For me the era ended when Greg Moore had his fatal accident. CART/Indycar was just never the same after that.
@@ILSRWY4 You are clueless. 1000 horsepower, sexy cars and you had Mario, Rahal, Tracy, Vasser, Zanardi etc racing. Now you have 650 HP easy to drive cars with a dumb looking, big ass windscreen.
The hole in front of the tail fin was for the series mandatory boost regulator. Maybe you could put a big nasty BOV there so it looks period correct and has a cool purpose 🤙🤙
@@ScottKenny1978 40 inches of mercury, 1.37 bar. They weren't that heavily boosted so the power was a combination of high RPM and the charge cooling of methanol fuel. Cars only got 1.85 mpg and they had a spray injector at the turbo outlet for evaporative cooling.
@@MGregoir ah, yeah. Sometimes they set things in inHg (usually an absolute measure) instead of psi boost. Edit: makes more sense to set a limit to an absolute measure.
ProMazda's been a thing in the support classes for Indycar for a while now. Maybe not a rotary these days, but I don't think the concept is as alien as you might expect.
Mounting an production car engine there is a very hard task because the input shaft is so low, and the engines are too high. Casey Putsch talked about this in his engine swaps video on his Formula and Indy cars, where he settled on a K series and a Hayabusa engine.
In Indy cars, the motor and transmission are part of the structure. This appears to be a CART era car from 1996-1999, according to Wikipedia, probably with a Ford Cosworth engine. That rusty frame in the engine area is probably a placeholder only.
They should buy a indycars engine from like andretti or like Penske, not a new engine but like a 2/3 season old engine that has been used a bit. I think it would be cool if a 90s Indy far has a modern engine
Hi Rob. Can't wait to see this up and running. If you need bits, Pit Lane Spares took over all the parts from Lola including tonnes of new T97/00 stock.
Rob, please reach out to people that know these cars. I can tell from the video straight away that this was likely a very long term show chassis, likely built up post crash. This may not even be safe to use.
I was a design engineer for Lola cars in Huntingdon, UK on the Champ Car/CART cars. My area of work was engine installation with exhausts, clutches and engine mounts to chassis and gearbox. I travelled to the races in the US as a support engineer. Great job. This just brings back so many memories.
@@connoisseuroftigolbitts with LED lights, it would not be hard to rig all the lights into the end plates on the aero. All that's left is figuring out a good place to stick the license plate. Back of the rear wing, maybe?
Enjoy the build and have some fun. As an avid IndyCar fan (open wheel fan), I can't wait to see this thing fire up with whatever engine you put in it. Rotary or even a little 4 banger turbo or v6 depending where you will be taking it.
He probably plans on building a brace that goes around the engine and takes the stress. I doubt a normal rotary would be up to taking those stresses, especially with the way that a rotary is put together.
@@shmoejoedesy9449 I wouldn't know because it never happened. I understood what you meant perfectly but apparently that thought didn't cross your mind 🤔
Above all the things you do... And all the cars you work on at the same time.. as a mechanic i have nothing but respect for you rob!... I know its hard to pump out videos... But the stuff you build and the vehicles that you build are solid. Keep doing you brother. And as always do work son!! Much love!
Don’t get carried away yet ROB you need to learn how to drive in a straight line 1st but I really wish you the best in this car road racing has become my passion and I can’t get enough of it I can’t recommend harder that you take lessons from a professional driver especially in a car like that they will teach you things you never even thought mattered and they will also teach you how not to die please get lessons brother that thing is amazing but once a car like that gets out of hand there’s pretty much no saving it
9:34, i believe the main use of those is actually adjusting the roll center and antidive/antisquat geometry of the car, the adjustments come as pre-set configurations, with the IR12 generation for example for a high antisquat rear end with fairly neutral roll center you would go some 20mm down from default, whatever that is, on the forward leg on both top and bottom A-arms. I say the main use, as they run the suspension so stiff you are not going to get a whole lot of camber gain, and especially not big swings from track to track :)
Using a standard rotary engine as a stressed member in car like this without a chassis isn't going to end well. Tension bolts through the rotary engine are not likely to hold up to the bending and twisting loads you will need it to endure. You should research how Mazda did it for their Let Mans car as that might be the only similar reference vehicle....
I agree 100%. As far as I am aware, the whole series of Mazda Group C cars has substantial supporting tubular structure between the monocoque and gearbox housing to carry through loads. Certainly the 787b and 792p are self-suporting without the engine installed. I have never seen a rotary engine used as a stressed member and I would think the nature of their construction precludes it.
@@ancientrenegade9243 Looks like most Indy engines are around 600mm length, 20Bs are 675mm so I think even a 4 is going to be a stretch. Maybe literally! Its obviously not going to be built to a class spec, so why not shove a few extra mm on the wheelbase to fit a novelty engine, and make some extended bodywork and fittings to suit.
@@ancientrenegade9243 The monocoque is autoclaved carbon fibre yes, but the monocoque consists of the cockpit and forward structural area. The rear structure of the car consists of the engine, gearbox and attached bodywork, there is no rear monocoque, that's why they split in half when they crash hard enough. You can absolutely extend the car by increasing the distance between the rear of the monocoque and the gearbox (either with an increase in engine length or a framework carrying the engine), it would require increasing the length of bodywork, linkages and fluid lines to match the new length, but that's it. If you have a look at an Indy monocoque you'll see what I mean :) NB by gearbox I mean the whole transaxle.
@@ancientrenegade9243 Oh it definitely wouldn't improve handling lol. Might improve stability on a big oval, but it would be ruinous for circuits, at least comparatively. I was only thinking for the sake of novelty powerplants, which I hope is the overriding goal of this project. Not enough people are having fun with motorsport anymore. I hope I didn't sound big-headed, I've been very lucky in my career to work with and have access to historic and modern racing cars of many different classes. I now work withh aircraft which is basically the same thing but upside down. Knowledge is secondary to enthusiasm!
Biggest problem may be that in the race configuration the engine is a stressed member - the front is bolted to the chassis bulkhead, and the transmission is bolted to the back of the engine.
oh my god, you absolutely should find a way to make active aero work on this thing. Turn it into a quad rotor time attack monster. With the quad rotor it'll sound like a monster of an indycar
The car looks like a lot of trips to the hardware store getting new bolts, but once the rust is all gone and it's refinished, it will look dope! I'm excited to see some love put into this machine.
I love Rob and this channel so much, And I will never stop watching. But my god please just get the 4 rotor dialed. If there is a setback I’m not aware about, y’all please tell me and I’ll delete this. But after the “this vs that”, I was so ready to see that thing solid and wrecking everything, but now it’s nowhere on the channel. Someone tell me what’s up or please Rob get that thing set up right.
No setback. I legit tore it down to measure and work on billet irons. I also didn’t want to slap it back together without the carbon body. So it doesn’t look so janky. Figured it would make a cool phase of the car. Videos will start coming out soon!
@@RobDahm so after watching you look over the car I realized you might need some help with formula cars. I work on and drive many different formula cars. Also If you would like to test any cars on a private road course let me know.
@@wheeln24-79 yeah man. I think that is where he will be going eventually but like he said in that other video he wants to get the 3 and 4 rotor designs dialed in first.
Time to fire up the HAAS boys… I feel some billet love coming just to mate the engine to the chassis. Oh and probably a new fuel tank, that baby probably deteriorated 17 years ago. Guess its time for another limited edition t-shirt run 😂
You are essentially laying down in the car, but he is also missing a seat. They are made custom for each driver. Most drivers would even have a oval and a road course/street course seet.
@@omega1575 you do remember correctly. Company in new zealand made those lik 13 years back, the lowest horsepower one was 1400hp N/A i believe. Thsy are going to do a revision series this or next year.
@@aaronbuster1989 my guess is 3 rotor turbo, if it will physically fit. It's a very snug fit in there, like 21" from firewall to bell housing, and you can't change it. May actually be limited to a 2 rotor due to length.
Exciting and beautiful looking car..I like the cleaning off of the dust outside to bring a shine to the bodywork..Bit of oily rag on the mechanicals will improve even more..I`d like a Le-mans sports GT car myself in the same condition to play with myself,but i could easily fall in love with that.
those i think are just rods to replace the actual suspension when storing this car. yes, modern f1 cars use torsion bars. but they are positioned differently. torsion rods twist instead of compressing. also because this is a CART car its most likely (definitely) has a normal spring and damper.
@@TheFoyer13 the bars on this car won't move or would do any dampening. I would think that the links would break if you drive this car fast and aggressive if the bars are used a the suspension.
Is it able to be insured to street drive? That would be...pretty much the most badass thing ever. (Maybe not California, but I'm sure in Florida you could)
If he is able to register it as a "kit car" it could possibly end up being street legal as long as it has all the other stuff required like working lights, mirrors and whatnot.
@@Wormweed California is kinda a pain in the ass (only one or two "kit cars" allowed in your lifetime!), but other states are much more chill about it.
The only reason I mention to the C8 drivetrain is because Rob may have a spare one sitting around, looking for a new home, at some point in the near future, that is all. I can't imagine that this car will ever be used in an actual Indycar competition, of any sort, so it's all about having fun with it, right?
@@Mike.W.Dasher The gearbox also has most of the suspension attachment points and houses the turbo. You're not putting any street car tranny in it. Fortunately, it's a common Hewland unit and every single little component of it is available.
Get a cad or solidworks surface reader scanner so you able to replicate the parts using the solidworks or CAD software. Metal 3d printers from Mark Forge, and a good vinal sticker specialist to remake stickers if any damage if occurred. Spares would be a must for a car of this nature.

Enjoy the build and have some fun. As an avid IndyCar fan (open wheel fan), I can't wait to see this thing fire up with whatever engine you put in it. Rotary or even a little 4 banger turbo or v6 depending where you will be taking it.
let's see this thing at Laguna Seca in the future!!!
That thing is asking for it, imagine how smooth it'll hit that bend coming down from the corkscrew when it's running
You should make sure that the rotary or shell you use has enough strength since it will be a structural member
He probably plans on building a brace that goes around the engine and takes the stress. I doubt a normal rotary would be up to taking those stresses, especially with the way that a rotary is put together.
"first thought in my mind is lets do meth" I think we all assumed you were already using lmao
I'm sure we all know he meant "Water/Methanol" when he said that

My man , I knew I liked this dude
I saw this car on Facebook marketplace months ago. I'm super excited for this build
Mazzei Formula gets a rear engined kit car racer.
Dahm: hold my beer…
Iv always wanted to see something run on vp racing’s 50-50 nitromethane and methanol… this is the perfect car
Finally the world knows! Officially, let's be honest we all knew 😂
Above all the things you do... And all the cars you work on at the same time.. as a mechanic i have nothing but respect for you rob!... I know its hard to pump out videos... But the stuff you build and the vehicles that you build are solid. Keep doing you brother. And as always do work son!! Much love!
God I haven’t seen a video from you since the 4 rotor I’m glad I came back this it dope
The silver bars connected to the cantilevers in the suspension are called dummy dampers. You'll need to buy actual springs and dampers to mount there
Starting at $1500 per pair (and that's for Lola, no Reynards anywhere I could find)... hopefully you can find the right ones.
Never clicked so fast but that title and Tumble just Pulled me in havent watch but already know its a good One for sure
Don’t get carried away yet ROB you need to learn how to drive in a straight line 1st but I really wish you the best in this car road racing has become my passion and I can’t get enough of it I can’t recommend harder that you take lessons from a professional driver especially in a car like that they will teach you things you never even thought mattered and they will also teach you how not to die please get lessons brother that thing is amazing but once a car like that gets out of hand there’s pretty much no saving it
9:34, i believe the main use of those is actually adjusting the roll center and antidive/antisquat geometry of the car, the adjustments come as pre-set configurations, with the IR12 generation for example for a high antisquat rear end with fairly neutral roll center you would go some 20mm down from default, whatever that is, on the forward leg on both top and bottom A-arms.
I say the main use, as they run the suspension so stiff you are not going to get a whole lot of camber gain, and especially not big swings from track to track :)
Wow! Richie Hearns DP T97 Lola what a find! Health to enjoy and rebuild!!!
It's missing its springs and dampers, it looks like solid rods were put in there so that the chassis could be rolled around.
Using a standard rotary engine as a stressed member in car like this without a chassis isn't going to end well. Tension bolts through the rotary engine are not likely to hold up to the bending and twisting loads you will need it to endure. You should research how Mazda did it for their Let Mans car as that might be the only similar reference vehicle....
Alternatively, you could create a frame around the engine to serve as the stressed member
I agree 100%. As far as I am aware, the whole series of Mazda Group C cars has substantial supporting tubular structure between the monocoque and gearbox housing to carry through loads. Certainly the 787b and 792p are self-suporting without the engine installed. I have never seen a rotary engine used as a stressed member and I would think the nature of their construction precludes it.
@@ancientrenegade9243 Looks like most Indy engines are around 600mm length, 20Bs are 675mm so I think even a 4 is going to be a stretch. Maybe literally! Its obviously not going to be built to a class spec, so why not shove a few extra mm on the wheelbase to fit a novelty engine, and make some extended bodywork and fittings to suit.
@@ancientrenegade9243 The monocoque is autoclaved carbon fibre yes, but the monocoque consists of the cockpit and forward structural area. The rear structure of the car consists of the engine, gearbox and attached bodywork, there is no rear monocoque, that's why they split in half when they crash hard enough. You can absolutely extend the car by increasing the distance between the rear of the monocoque and the gearbox (either with an increase in engine length or a framework carrying the engine), it would require increasing the length of bodywork, linkages and fluid lines to match the new length, but that's it. If you have a look at an Indy monocoque you'll see what I mean :) NB by gearbox I mean the whole transaxle.
@@ancientrenegade9243 Oh it definitely wouldn't improve handling lol. Might improve stability on a big oval, but it would be ruinous for circuits, at least comparatively. I was only thinking for the sake of novelty powerplants, which I hope is the overriding goal of this project. Not enough people are having fun with motorsport anymore.
I hope I didn't sound big-headed, I've been very lucky in my career to work with and have access to historic and modern racing cars of many different classes. I now work withh aircraft which is basically the same thing but upside down.
Knowledge is secondary to enthusiasm!
you know you can always copy F1 radiator cooling and intercooling layouts if you want 🤩
its probably got the forward slanty radiator setup anyways, thats been around a long time im sure...
Biggest problem may be that in the race configuration the engine is a stressed member - the front is bolted to the chassis bulkhead, and the transmission is bolted to the back of the engine.
That Pole Position starting sound @1:40 lol. Subtle Rob.
oh my god, you absolutely should find a way to make active aero work on this thing. Turn it into a quad rotor time attack monster. With the quad rotor it'll sound like a monster of an indycar
"I've got child bearing shoulders"
-Rob Dahm- 2021
I wanna see this build with a 5 rotor..., but finish 2 rotor, 3 rotor, 4 rotor and the 6 rotor first, dahm it!!!
The car looks like a lot of trips to the hardware store getting new bolts, but once the rust is all gone and it's refinished, it will look dope! I'm excited to see some love put into this machine.
Not buying these bolts at a hardware store. It's all aviation hardware.
Epic well I hope you guys clean it with dry ice to not damage sensitive areas
I love Rob and this channel so much, And I will never stop watching. But my god please just get the 4 rotor dialed. If there is a setback I’m not aware about, y’all please tell me and I’ll delete this. But after the “this vs that”, I was so ready to see that thing solid and wrecking everything, but now it’s nowhere on the channel. Someone tell me what’s up or please Rob get that thing set up right.
No setback. I legit tore it down to measure and work on billet irons. I also didn’t want to slap it back together without the carbon body. So it doesn’t look so janky. Figured it would make a cool phase of the car. Videos will start coming out soon!
@@RobDahm so after watching you look over the car I realized you might need some help with formula cars. I work on and drive many different formula cars. Also If you would like to test any cars on a private road course let me know.
Everything takes time mate relax
@@thomasclark6642 I know, it's just easier with some help.
@@trusty9796 you're awesome!
ROB WHY U UPLOAD AT RANDOM TIMES NOW I GOTTA WATCH WHILE WORKING
💀
So is Isaiah going to take revenge and pee on the Indy car 🤣🤣
It didn’t earn its keep! He couldn’t drive it in, after all
Rob you mad lad. So keen to see where this goes
So damn excited for this! Nobody else is doing this!
"We've got a couple 4 rotors chilling" get to work guys!
Fugg that man, this deserves a sixrotor.
@@3campbep I'm sure that what he put in it if there was room. A 4 rotor will still make this thing a ton of fun!
@@wheeln24-79 yeah man. I think that is where he will be going eventually but like he said in that other video he wants to get the 3 and 4 rotor designs dialed in first.
Time to fire up the HAAS boys… I feel some billet love coming just to mate the engine to the chassis. Oh and probably a new fuel tank, that baby probably deteriorated 17 years ago. Guess its time for another limited edition t-shirt run 😂
HAAS and open wheel haven't been having the best time together recently
@@acreativename7999 Mick Schumacher wants to know your location
I love for how technically crazy this car is, Rob is certain that one of the ducts is for his balls lmao
so glad I was one of the hundreds of people who tagged rob in this forsale post
Watching Rob get in the Indycar is eye opening. Had no idea how much you had to lean back.
You are essentially laying down in the car, but he is also missing a seat. They are made custom for each driver. Most drivers would even have a oval and a road course/street course seet.
@@dhj2098 Didn't know that. That's pretty cool.
Rob Dahm quote of the day " my first thought let's do meth" lol
running meth is a way of life, it's hard to let go once you've dealt with it.
Bro gonna rotary swap a tank one day
I’ve seen a 12 rotor boat engine (if I remember correctly) that could power a tank
@@omega1575 you do remember correctly. Company in new zealand made those lik 13 years back, the lowest horsepower one was 1400hp N/A i believe. Thsy are going to do a revision series this or next year.
There's finally be space for an engine. I'm really curious if he goes 3/4 rotor NA or 2/3 rotor turbo.
@@aaronbuster1989 my guess is 3 rotor turbo, if it will physically fit. It's a very snug fit in there, like 21" from firewall to bell housing, and you can't change it.
May actually be limited to a 2 rotor due to length.
Everyone in the comment section old enough to remember who Richie Hearn is raise your hand. Bonus points if you knew him when he was go kart racing.
I started watching CART back in '98 and watched him race for John Della Penna.
This was a tease. Need more of this car.
Exciting and beautiful looking car..I like the cleaning off of the dust outside to bring a shine to the bodywork..Bit of oily rag on the mechanicals will improve even more..I`d like a Le-mans sports GT car myself in the same condition to play with myself,but i could easily fall in love with that.
10:43 "where's the spring?"
those might be torsion bars, aka suspension without springs.
they use them in f1, and i assume indycar as well
those i think are just rods to replace the actual suspension when storing this car. yes, modern f1 cars use torsion bars. but they are positioned differently. torsion rods twist instead of compressing. also because this is a CART car its most likely (definitely) has a normal spring and damper.
Not in 1997 they didn't. Those are gone and replaced with these, I'm wondering if they even move. They look solid.
The roll bar is torsional front and back. I have multimatic dampers set up for this
@@TheFoyer13 the bars on this car won't move or would do any dampening. I would think that the links would break if you drive this car fast and aggressive if the bars are used a the suspension.
@@br1_deadpedal Did the T97/00 originally have Ohlins TT4s?
Rob in three years:
I dont fit in the 6 rotor anymore i need to watch my diet so im going to swap it into a Mazda REPU
6rotor won't fit, engine bay is too short. I think the best this can take is a 3rotor.
Pls just do it the Right way! i don't care if we have to wait 3 Years but pls build it right!
So I'm genuinely happy for you Rob but I'm still in tears. This was all our dreams.
You can get one yourself if you really want… They cost less than 20k these days.
LookN forward to following this build
Is it able to be insured to street drive?
That would be...pretty much the most badass thing ever.
(Maybe not California, but I'm sure in Florida you could)
If he is able to register it as a "kit car" it could possibly end up being street legal as long as it has all the other stuff required like working lights, mirrors and whatnot.
Can't you get plates on everything in the US?
@@Wormweed just about. It depends on the state but yeah there's a way to make almost anything road legal here.
@@Wormweed not sure, I'm canadian, I just know California is pretty annoying with all their restrictions..more than here in BC
@@Wormweed California is kinda a pain in the ass (only one or two "kit cars" allowed in your lifetime!), but other states are much more chill about it.
I know the rotory would be cooler, but I have to wonder if the C8 drivetrain would fit in that thing.
Less reliable than a rotary 🤣
A ls would be giant for an Indy car. Way way to much weight and torque. Not enough HP and revs. That car is like 1400lbs.
They had GM V8s back then....About 200 cubic inch V8s
The only reason I mention to the C8 drivetrain is because Rob may have a spare one sitting around, looking for a new home, at some point in the near future, that is all. I can't imagine that this car will ever be used in an actual Indycar competition, of any sort, so it's all about having fun with it, right?
@@Mike.W.Dasher The gearbox also has most of the suspension attachment points and houses the turbo. You're not putting any street car tranny in it. Fortunately, it's a common Hewland unit and every single little component of it is available.
I was here, this is for the future when people look at project as a relic of history. I was here.
Hey rob! I work for an Indycar team that may have some old suspension parts that are less rusted and may help freshen up what you are working on.
Keep the livery. Ralphs is the name of the rippers in my city lol. Also this is EPIC
"my first thought was, lets do meth!" me too Rob - only 2 more sleeps till xmas baby!!! woooo!!!!!!
Lol
Everyone: Rob do you like more 4 rotors or 6 rotors?
Rob: Yes
Get a cad or solidworks surface reader scanner so you able to replicate the parts using the solidworks or CAD software. Metal 3d printers from Mark Forge, and a good vinal sticker specialist to remake stickers if any damage if occurred. Spares would be a must for a car of this nature.
Rob you will need a bigger shop! Living the dream. Good on you!
Love this 😀
One question. What happens if you break literally one proprietary part on that car?
He's got a machine shop, I'm sure that he could make something to fix it
@@Skrillfreak I get that but hopefully he can swap at least the drivetrain so he's not remachining every time he drives the thing.
@@personguy3137 Alternatively, it’s probably a production gearbox that he just has to make a few friends to be able to purchase new
@@Cjbarker2 it is def not a production gearbox lmao. It’s a transaxle, and it’s also the rear suspension mounting points
it's probably a hewland. there's new old stock parts available
