A local friend of mine is building a Spirit R/T and has come a long way with it. We are wondering just how far we can go (safely), and make even more power. This car is head and shoulders above anything I've built before. Current boost level is ~ 20 psi.

Current owner wants to know how much the boost can be turned up....Since he has put a solenoid in to power the fuel pump, the A/F ratio at WOT seems to be good (high 11s to 12.0 @ WOT). I told him he might well have to look into a higher octane fuel to play safely. How much boost is this combo capable of and can it approach 500 WHP or are we just dreaming?
