Anyone out here with the saleen supercharger making more than the 4.5psi it puts out from factory? Id like to upgrade to around 10psi but i think the saleen supercharger upgrade is for 5-7psi with a saleen reflash,belt,pulley and 39lb injectors.....my question is this, does an 05-06 saleen sc81 sc have addequate enough fuel system to upgrade to 9-10psi with just doing bigger injectors, pulley,belt, and a retune....im thinking of just having a custom tune done and going with 60lb injectors...what setups are reccomended for 10psi, meaning what chip or tuner to use, what size pulley and belt,what maf to use etc etc and will i have to upgrade fuel system to make the extra boost?
