How does changing the supercharger pulley size affect performance?

Changing the pulley size alters the speed at which the supercharger spins relative to the engine's RPM. A smaller pulley, like this 2.625-inch one, will make the supercharger spin faster, generally increasing boost pressure and horsepower. A larger pulley will do the opposite.

What is the finish on this Edelbrock pulley?

This Edelbrock pulley features a black anodized finish. Anodizing helps protect the aluminum pulley from corrosion and wear, while also providing a durable, non-reflective black appearance.

Can this pulley be used with any Edelbrock supercharger system?

This specific pulley (part #15814) is intended for use with Edelbrock's Professional Tuner systems and E-Force Supercharger Systems, particularly those configured for the Stage 3 Pro Tuner setup. It's important to verify compatibility with your exact supercharger kit.
