    07 rxp is there such thing as too much boost

    so i got a 07 rxp with pump wedge, opas block off, 15/21(over propped), r&d grate, fizzle intake, fizzle intercooler, x-charger, riva rear exit waterbox, rive fuel pressure regulator, bugger injector(cant remember what size), 158 thermo, and prob forgetting some stuff.

    im looking at getting the biggest wheel for the x-charger, then maybe valvetrain upgrade and a ecu.

    i wanna say im running around 10-11lbs right now but not positive

    but is there such thing as running to much boost in these motors?

    loaded question big time. If you keep the fueling right you can run up to around 17psi before you crack the intake manifold.
