Sorry spaced on the pulley size, I went from the 2.76 to the 2.85.According to apten it works best with the apten ported blower and doesnt work the blower as hard, plus it was already on the ported blowerASD said:Nice #'s ED!What pulley did you put on?(2.93) Now you need a lower 4lb or 6lb and you will get the torque up over 500.

Remember i'm still a beginner only 2 seasons of rookie racing, im a late bloomer

10:1 compression on Mach may make that a better option than s/c.
