            I have 8.2:1. I'm shooting to push the 15-18 psi range (intercooled) this racing season.

            Nobody knows how much it can handle, no one has ever gone that high before. [img]smile.gif[/img]

            EDIT: Okay, GTP's have, but they have roots blowers and their powerband is vastly different from the exponential boost curve that a centrifugal supercharger or a turbo produces.

                    i have been ther for the lat3 months lol. i have seen over 30 and my motor is still alive. you have too built what you need too handle what you want. if you wnat a motor too handle 10psi, then build that. if you want a motor too handle 100psi, then that is attainable also. just make sure you have enough fuel or you will be sorry.lol
                    boost, you got it???

                        what internals you have i know stephen has the L67 internals, and if he can push 18 PSI on them i should be able to go well into the 20's
