i had a guy tell me he had 500 horse, so i asked him what kind of boost he was hitting, he said about 40psi. his truck is fast, but i have hit 50psi in my truck and i know im not at 500 horse. Is he full of it? im just asking is there a ratio for boost compared to hp?

he is probably right......ask him what his last dyno run looked like. boost:power ratio..........................eh their related but its not an exact ratio because different turbos, and all kinda other crap. for instance a stock hx35 can boost pretty high, but once you reach a certain point its just blowing hot air and your not making any more power anyway.

If he has a stock turbo it is impossible to hit 500 hp. now if he hit 500hp on only 40lbs of boost he has a bigger volume of 40lbs of air goin into that motor.

in theory an 8" pipe full of 40lb of pressurized air is not the same as a 4" pipe filled with 40lbs of pressurized air.

456 was the highest i got on a HX35 and the only way i got that was with a piece of Duct tape of the pyro.
