I wonder what the redline is? Someone claimed when it was released that it was actually less than the production car, but I find that hard to believe.

Neither would I, but there was a guy who was adamant that it was lower than the production car which to me sounds all wrong. That's why I want to know for sure.

I think they should use they M3 OEM front and rear brake system, since they are soooo good.

These specs are probably 90% true. Each camp has to have their own little secrets to make things more interesting and competitive...

We shall see how it will do on the track...we shall see...

Does anyone know if there is a displacement limit for GT2 class? If Mercedes wanted to enter a 700hp+ 6.2L CLK, could they?

It was me who "claimed" the revs are lower.

Two words: air restrictors.

Believe what you will, but my current information is that the ALMS motor will not rev higher than the production motor.

Its a reasonable claim, and your contribution is of course appreciated. Its just that without an official source its not of much practical use to me.

Wow. Someone's a little touchy. I never said you made it up - never. I just cannot consider things I here on a forum as fact unless a source is cited.

Me: "Yeah I here the race car will only rev as high as the production car."
Others: "Really, where'd you read that?"
Me: "An internet forum."
Others: :Hearty Laughter:

Its really kinda funny that you are having a hard time understanding that people aren't just going to take your word and getting all hurt.

Bye.

Looks like a limit of 8400 revs has been confirmed by an official source.
