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 generally spins the supercharger faster, increasing boost pressure and airflow, which can lead to more power. A larger pulley spins it slower, reducing boost and potentially improving fuel efficiency or making power delivery smoother.

What is the finish on this Edelbrock pulley?

This Edelbrock pulley features a black anodized finish. Anodizing is a process that hardens the surface and provides a durable, corrosion-resistant coating.

Can this pulley be used with any Edelbrock supercharger system?

This specific pulley, part number 15825, is designed for use with Edelbrock's Professional Tuner systems, particularly Stage-3 configurations. It's important to verify compatibility with your exact Edelbrock supercharger model.
