What is the main benefit of changing the supercharger pulley size?

Changing the supercharger pulley size allows you to alter the drive ratio between the supercharger and the engine. A smaller pulley generally spins the supercharger faster, increasing boost pressure and airflow, which can lead to more power.

Why does this pulley have 8 ribs?

The 8-rib design is intended for higher-performance applications and offers more surface area contact with the drive belt. This results in improved traction and stability, reducing the likelihood of belt slippage, especially when the supercharger is under significant load.

Is this pulley compatible with all Edelbrock supercharger systems?

This specific 3.25-inch, 8-rib pulley is designed for use with Edelbrock's E-Force Supercharger Systems and their Professional Tuner systems. It's important to verify compatibility with your exact supercharger model.

Product Details

If you're looking to dial in the exact boost level for your Edelbrock E-Force Supercharger System, this 3.25-inch, 8-rib pulley is a key component. It allows you to precisely adjust the airflow and overall performance to match your specific tuning preferences and driving style. This pulley is designed to work with Edelbrock's Professional Tuner systems, ensuring a solid connection and reliable operation.

This pulley is constructed with an 8-rib design, which offers improved traction and stability compared to a standard V-belt setup. This means less chance of belt slippage, especially under heavy load, so you get consistent boost and performance. The black anodized finish not only looks sharp but also helps protect the pulley from corrosion, keeping it looking good and functioning well for a long time. It's a well-built piece that helps you get the most out of your supercharger setup.
