i installed a 255lph fuel pump and a kirban regulator last week and i am curious as to what i should set the fuel pressure at? i have a gauge hooked to the schrader valve on the fuel line, and with the vaccum off the regulator i have it set at about 47psi. i know that is rich, but i wanted to be careful. i'm running a stock bottom end, stock heads, stock cam, 1.7 rocker arms, performer 5.0 intake, 73 maf, 65 tb, 24lb injectors, and a 9psi powerdyne supercharger. i also only run 93 octane gas in the car, nothing below, and i haven't ever bought 100 or better either, only 93.
