Most likely not get an answer here and a search for those who may race the mentioned model could yield contacts once you know who the players are.

 

Which generation of car?

I've got a Gen 2 Conti GTC Speed which is a W12 with 626HP or so. It doesn't need any more than that because the chassis isn't up to it in my opinion. Whilst you can hustle it around the bends, it's more the straight line hero.

 

It would seem to me that tuning one of those would have to start with weight (ie the V8).

Otherwise just get one of the std W12s and be happy with it.

 

Buy a GTC Speed, it has about 650 HP.
Drive it before thinking upgrading, because that is indeed a lot of power and sufficient according to some owners.

 

I am looking at a 2020 or later V8.

Thanks for the help.

 

I bought a tune for my 2007 gtc from vr racing
