What PSI to run?

[parchisi]

Ok, i'm looking at a ProCharger D-1SC and there are options for boost level ranging from 15psi to 22 psi. I'm shooting for 600 hp and I'm wondering how much boost would get me there without blowing up my shortblock.

I have AFR 185's, dished pistons, I have no idea what my compression is...i'm going to call of the guy who put the combo together to figure that out, and the camshaft is pretty mild at .510 intake and .515 exhaust lift, at 291 and 295 degrees advertised duration respectively. Thanks.

yeah, definately find out what compression that thing has.

and what is the lobe seperation on the cam?

i'd say get a more blower friendly cam (closer to 114 lsa), one that has higher lift and won't starve the engine for air. then you won't need as much boost.

the better it runs n/a, the less boost you need to make your goal.

figure 14.7 psi to double your hp.
