What does changing the supercharger pulley size do?

Changing the supercharger pulley size alters the drive ratio between the supercharger and the engine's crankshaft. A smaller pulley on the supercharger typically spins it faster, which can increase boost pressure and engine power, while a larger pulley spins it slower, reducing boost.

What systems is this Edelbrock pulley compatible with?

This pulley is specifically designed for use with Edelbrock's E-Force Supercharger Professional Tuner systems. Always confirm compatibility with your specific supercharger kit.

Does this pulley come with any hardware?

The manufacturer description does not specify if hardware is included with this pulley. It is recommended to refer to the complete kit instructions or contact Edelbrock for details.
