Damn! first of all NICE teg! I'm doing a similar performance build and from what I've gathered after talking to some local tuning shops and such, your setup (basically) on say 100+ octane and 25 psi boost can make 550+ whp.....now with say 15 psi and 91 pump gas definitely 350+whp...care to post any dyno info if you have it? Nice car!
