How does changing the supercharger pulley size affect performance?

Changing the pulley size alters the drive ratio between the engine and the supercharger. A smaller pulley makes the supercharger spin faster relative to engine speed, increasing boost pressure and airflow. A larger pulley does the opposite, reducing boost and airflow.

What is the benefit of a 10-rib design?

The 10-rib design is intended to match the supercharger's drive belt. This wider belt surface area provides more contact and better grip, reducing the chance of belt slippage and ensuring consistent boost delivery.

Is this pulley compatible with all Edelbrock superchargers?

This specific pulley is designed for Edelbrock's Enforcer Supercharger systems. It's important to confirm that your supercharger system uses a 10-rib belt and is designed to accept a 3.875-inch pulley for optimal fitment and performance.

Product Details

This 3.875-inch diameter pulley features a 10-rib design, specifically made to work with Edelbrock's Enforcer Supercharger systems. The rib count is important because it matches the belt on your supercharger drive, ensuring solid engagement and efficient power transfer without slippage. By changing the pulley size, you can adjust how quickly the supercharger spins relative to the engine's RPM, which directly impacts the boost pressure and overall airflow into your engine. This allows you to tailor the performance characteristics of your street rod, muscle car, or Corvette to your specific preferences.

The black anodized finish not only looks sharp but also helps protect the pulley from corrosion. This part is designed to let you fine-tune the airflow and performance of your Edelbrock supercharger system, giving you more control over how your engine responds. It's a key component for dialing in the boost levels for your particular setup.
