What does changing the supercharger pulley size do?

Changing the supercharger pulley size alters the speed at which the supercharger spins relative to the engine's crankshaft. A smaller pulley on the supercharger (or a larger one on the crank) typically increases boost pressure, leading to more airflow and potentially more power. This pulley allows you to fine-tune that airflow and performance.

What is the finish on this pulley?

This pulley has a black anodized finish. Anodizing is a process that hardens the surface and provides corrosion resistance, while the black color offers a clean, stealthy look.

Can this pulley be used with any Edelbrock supercharger?

This specific pulley is designed for use with Edelbrock's Professional Tuner systems, particularly Stage-3 configurations. It's important to verify that your supercharger system is compatible with this pulley size and rib count before installation.
