8Rib Super Charger Pulley 8.65 DIA
8Rib Super Charger Pulley 8.65 DIA
Price Each: $249.99

This Pulley is a direct replacement for the 8 rib 7.65 dia pulley part# ATI DC017A-008 commonly used
on 98-02 F-Bodys equipped with LS1 engines using ProCharger brand superchargers.

This 8 Rib pulley is 8.65 inches diameter! A full 1 inch larger than the pulley supplied with other 8 rib kits.
Increasing boost with superchargers is simple, increase the supercharger rpm relative to the engine rpm.
This is done in one of two ways.

1: Put a smaller pulley on the supercharger.
This is counter productive for 2 reasons, 1 it requires more torque to turn the supercharger to make more boost and
2 the smaller pulley has less belt contact. Less belt contact leads to belt slip and premature belt failure.
Belt slip decreases boost the very thing you are trying to increase. To sum it up, putting a smaller pulley on the superchager
to increase boost is counter productive.

2: Putting a larger pulley on the crankshaft of the motor will increase boost and increase belt contact area.
This is a no compromise solution to increasing boost of a supercharger.
