hybrdthry911 knows what he's talking about.PSI isn't everything. You can have a high PSI setup that runs hot and produces less power but more importantly is worse for your engine. You want cool dense air even at a lower psi.Also, where the boost is delivered in the RPM band can also have some affects when you're really threading the needle of "safety"In my short time here 325-375whp is generally the safety margin I see. Some folks go 400hp but sooner or later they're rebuilding from leaky/busted ring lands or what not. FWIW you can get to 325-375 at roughly 5-7lbs of boost. 400 can be achieved at 9lbs+ in general. YMMV
