Update:
Had a problem with the car... Engine has maybe 100 miles on it, and the headgasket is blown pretty bad. Im actually surprised that it didnt blow on the dyno... The oil is chocolate milk now, but never looked very clean in this engine. The engine never overheated and ran okay... It looks to me like the head is warped though, so it must have been like that since installation. The engine has head studs on a stock composite gasket and the block is decked... The engine still has 70+ psi oil pressure hot so im betting the bottom end is still ok, but the cam looks marginal. Im gonna have to have my machinist take a look at it. Fuck this shit sucks
edit:
Thats probably why i could only get 429whp at 26psi boost, I felt it should have been 500+whp. At least I feel a little better knowing that the headgasket must have been messed up before we even showed up on the dyno.
