Under drive crank pulley

[koji77]

Can you run an underdrive crank pulley with a supercharger??? I have an ATI p1SC, wondering if I could put an underdrive on the crank... will the ATI crank pulley bolt up???

I know you can't with the 8 rib setup, and you cannot with the vortech, as they both use the ATI superdampener.

I don't think the 6 rib will bolt up, but im not sure.

We actually use a 10% under driven ATI Harmonic Balancer/Dampner with the ATI ProCharger 8 rib units. I have the part number at the shop for it, if anyone needs it. Bob :)
