Re: Results with 3.2 Carrera heads on a turbo engine?

So, for all those running 3.2 heads on your turbo engine who have a dyno graph could you please post those dyno results along with a basic engine build sheet containing key parameters.
Noah,
I'd take a good look at cam specs - I'd expect that the 930 cam won't benefit much, if at all from the 3.2 head's bigger ports. Also, from what I've done with engine analyzer, it didn't seem that the program simulated forced induction accurately, especially with respect to cam profile. Most of the blown cars that I saw seemed to make more hp and torque than engine analyzer predicted.

Good luck!
