F1c and F1R won't get you 1000rwhp..atleast not without a VERY aggressive tune... An R is done at 950 rwhp on average..and larger the cubes, sooner it will peak and nose over.

I'm of the camp of medium compression, more boost and less timing. In my experience, timing will yack head gaskets(detonation) faster then boost.

Thick deck heads and atleast ARP 2000 head studs are a good idea.

Good luck on your build.


Me and Detoxx are on the same page on this stuff....I guess because we've done it.
on the money
