    Question Proper boost and rpm. 08 PX

    What should the max SC boost, and max "wot on the water" RPM's on a stock 08 rxp-x be?
    My RPM's are between 8040 & 8080 depending on conditions. "Just curious about the boost"

    Rev limit is 8080-8100 rpm
    approximate boost levels in psi

    stock RXP-X SC
    9.8 psi @8100
    11.2 psi @8500
    11.6 psi @8700

    Has your RPM always been 7800 or is this something new?
