Approximating turbo/SC gains

[roksoc]

Hey guys I think I read somewhere on the site that 1 psi of boost would create 10hp. Is this true is there a way to approximate how much of a gain you would get with say a 10psi turbo kit. Is there anyway to say that a ceratin amount of psi is equal to a certain amount of hp. Is there a formula of some sort that may be applied to this situation?

The reason I am asking is simply curious and I hope to make some changes to the car in the summer but I want to get to know as much as possible.

it varies by vehicle/engine. 10psi on one engine might net you 40 hp and 10 psi on a different might give you 75.

^agreed. Plus it depends on the effinecy of the particular turbo/SC that you choose. RSM's bolt on SC kits I think net 60 hp for the Stage I kit, 80hp for their Stage 2. Those are for a certain vehicle though so can't really say what that same kit would do for another vehicle. But to give a rough esitmate you can say 10hp for every 1psi. But most of the time 10psi is going to be giving you around 30-50hp,not 100hp.
