Hi, I have installed my Whipple supercharger, pulley diameter is 3.25 inches, are on the dyno, and although there is a problem of inadequate gas flow, which we solve with 2 gas pumps, the drive is no more than 5 psi . I have installed the injectors 39 pounds and is 90 mm MAF, the programmer is an SCT X3 and the results on the dyno are about 315 HP, a number quite poor, of course, I am aware that the gas flow is not appropriate but, because the impulse does not rise. Do you think might be happening? . Please someone who can help.
