ATI Performance Products
We think ATI Performance Products’ [www.atiracing.com] new Super Pulley (for engines sporting standard or reverse-rotation ProCharger P1, D1, F1, F2 and F3 superchargers) is a great step in a new direction for the company that’s better known for its high-performance transmissions, converters and harmonic balancers (dampers). Superior Sprag Technology in this new, 45-tooth cog (PN 916195-45) allows it to release when the blower’s rpm is higher than the engine’s revs (between shifts in a stick car, for example). The pulley’s ability to freewheel reduces wear and tear on the blower and your wallet, as it keeps expensive belts from snapping if you’re on-and-off the gas.
