Utterly epic and I salute you for doing this. I only have one negative though. Please don't try to make it look exactly like a F1. The engineering project that you are undertaking is so fantastic that I feel it would be a real shame for it to be written off as pastiche of the F1. By all means, the F1 should serve as inspiration and provide styling cues, but as you have gone your own way on the engineering, maybe go your own way on the styling. Make it truly yours.

Just my unqualified 2p's worth.

This, respectfully. What you’re doing is epic, and deserves to be yours, not an F1 “rip off”.

And also, sending a couple of buckets of gumption from the UK, via container ship. Should arrive just around one of those more challenging times.

Looks like an incredible project!
The drivetrain solution sounds complex, but having a few "blow em up and replace them" rover k series, I see the logic in it
Really interested in seeing how the mechanical side all fits together. Twin engine stuff pops up occasionally, but it's usually one drivetrain at each end!
If it works well it would be a very cool and unusual v12-ish setup!

[Gameface]

Yeah, making an F1 clone cheapens all the incredible effort that will go into the build.

Best of luck with it.

[threespires]

This sounds wonderful.
If you can have it running before the first TVR is delivered, then I'll be exceedingly impressed. ☺☺

Wonderful idea, be good to follow this through, must agree with others.

Try not to ‘replicate’ too much, make it your own.

Thanks for all the encouragement, I really appreciate the honest feedback - I have no ego in this and critical opinions are welcomed. It is impossible to see your own work subjectively, which is why I think most people should not style their own cars! Maybe if I had gone to the RCA....

I would probably style something like this - https://simpsons.fandom.com/wiki/The_Homer

Seriously though this car will be capable of EXTREMELY high speeds, the geartrain and suspension are the same part numbers as the C6 Z06 and have been validated up to 198mph (320kmh) with 505 HP (drag coefficient of 0.34 according to GM). The fastest I have ever driven is 125 mph for a short burst down the straight at the Nurburgring - I am talking about adding the UK speed limit on top of that. The high speed run at Nardo was done with under 600HP. It will not take much development to create 600-700HP from the twin engine setup - hence wanting to bring the center of mass as far forward as possible - the COP for the F1 is stable with a 40/60 weight split. With more power and the low drag coeffcient this cars potential is getting into very dangerous territory and instability caused by ineffective aerodynamic design could be fatal.

I would very much like to survive past the first trackday, so decided early on that piggybacking off aerodynamic development conducted in a proper windtunnel by boffins was not just a styling decision, but a safety one too. The shape is well proven in the wild (thanks to Dr Thomas Bscher) and stable at high speed, and produces downforce without external aerodynamic devices - I seriously don't think I could improve on that by guessing or using tufts of wool.

Another reason that reassures me is the fact that all the original patents are now in the public domain and can be used - which means we can all utilise the technology mclaren patented if desired - worth a look.

I think even Gordon Murray himself might have had to wait for the Mclaren patents to expire before publicising the T50??

Much appreciated, I am getting through my current stocks quicker than expected!

One day, some time in the 2020s, you will have finished it, this thread will have hundreds of pages, will have inspired hundreds if not thousands of people and I will be able to say I was in it from the start.

What a truly incredible project.

I’ve called it now, don’t fail me OP!

Thanks mate, you just earned a drive in it when its done!

[xjay1337]

Will follow this. Hope there are regular updates as the old thread with the cad parts sort of died and it was very interesting!

Sounds great, but I would seriously jack in that twin engine idea for a crate V8.

Unfortunately an LS motor doesn't fit onto the transaxle with the 107" wheelbase - it was one of the first ideas I assessed but something has to go transverse to fit it all in.

I am hoping this project will entice crosseyedlion back and maybe some collaboration...???

[dom9]

Looking forward to updates, OP!

[AmosMoses]

Mad, cant wait to see progress!

[shalmaneser]

Total insanity, i hope it works.

Would be much better off without the twin engined concept, though. A Pagani-style merc v12 and a porsche transaxle must be a better solution?

€75 could help shorten the time to get your surfaces right. These models aren't perfect, but they're a good start!

Regarding the windscreen. Have you looked at the Lotus Elan M100? Not a million miles away I would suggest.

[Piha]

OP, this is utterly fabulous.

OP, if you are using the C6 gearbox and diff it might be worth looking at the Zr1 version. The tr6060 and diff are stronger than the stock c6 version.

[F1natic]

Not able to get much done this weekend due to work commitments - have layed out some of the interior ergonomics ahead of the full scale cabin mockup.

Got some 3D prints due off in a few hours.

you are absolutely right, the ZR1 is the ultimate box. After 2009 both the base Corvette and the Z06 used the TR6060 - designated as MM6 code, which is validated to 500 lb-ft of torque (around 680 NM). The TR6060 with the Z51 option features closer ratios and is designated as MZ6 - but is only validated to 430 lb-ft of torque. The ultra high performance ZR1 uses the TR6060 designated as the MH3, which is validated to 650 lb-ft of torque.

However I am planning to use a low mileage box for initial testing and in 8 years of watching Ebay I have never seen a ZR1 box - they are rare. The MM6 is within my budget and pop up often at reasonable prices, much lower than a porsche G50.
