Hi all , I have a couple of questions I hope can be answered.

I reciently bought a used Whipple Supercharger kit for a 1988-1995 Chevrolet TBI pickup truck application, and need to know what the part number is for the longer serpantine belt that is needed for the conversion.(It came without a belt)
I think it may be a NAPA 061025, but Im not sure.

The supercharger itself is one of the Opcon Autorotor units , what is the normal backlash specs for the gears in the front casing, and what type of oil do Whipple reccomend to be used in the gear housing?

Thanks,

Wayne

bump, i need some help on this too
