After driving at Spa on the 12th of may, the engine was not running 100% even if the car was quite fast. So I decided to check exaclty.

Basicaly, I have lost 63 bhp and 123 Nm somewhere !
It must not be a big deal, I just nee dto find out where is the problem and afterwards....

As I am doing a lot of upgrades at the same time, I never know well the car when going on track. So it's quite uneasy to say if something is wrong. This time, I was faster by more than 4 sec per lap where I indeed have 22 bhp less... This preparation is "soft", it does not need any fuel modification. The turbo is still a OEM turbo (LEH). It seems it is a basic loss of air presure, somewhere. I just need to find it 
The worst for me is losing time, as I need to go on my new light body...

Almost nothing... I have a lose somewhere. I already found a small problem, but when solved, still the same presure... I will tell you more when I will found it ! 
I will do it soon, but I can tell it push like never, so it works
What I found very strange is how a basic 2.0 GM without turbo and without Vtec can produce 245 BHP
Bon, c'est pas l'tout, mais maintenant qu'on a assez perdu de temps pour trouver pourquoi un vulgaire petit 2.0 GM non vtec et atmosphérique ne sortait que 245cv (il faudra qu'on m'explique...), on passe à la suite !
I am now going to install this turbo cooling system in order to decruise the engine bay temperature. This associated to the new CF body opended behind and without boot. But unfortunately, this is quite heavy...
I will weight it before fitting it:
After a full month of hard search, I found it !
I will fit it at the same time with the front CF body and I will clean of all the heavy stuff. Extra weight foreseen: - 4,68kg

Which GM engine with 245BHP do you mean? If you're talking about the "old" C20XE 2.0 16V engine, that is possible with extensive mods. (Tuned for throttle bodies etc.)rapidos schreef: What I found very strange is how a basic 2.0 GM without turbo and without Vtec can produce 245 BHP

But in standard form it was 150BHP...
