ATI Performance Products 916227 Supercharger Pulley 9.34" Diameter 8-Groove

The ATI Performance Products 916227 is a precision-engineered supercharger pulley designed for high-performance forced induction applications. This pulley features a 9.34-inch diameter and an 8-groove serpentine belt configuration, making it compatible with a wide range of supercharger setups.

Key Features:

• 9.34-inch outer diameter for specific boost and rpm characteristics
• 8-groove serpentine design ensures optimal belt grip and power transfer
• Precision-machined construction for accurate fitment and balance
• Engineered to reduce parasitic drag while maintaining boost levels
• Compatible with popular supercharger systems requiring 8-rib belt drives

Changing supercharger pulley size is one of the most effective methods for tuning boost pressure and optimizing performance. A larger diameter pulley like this 9.34-inch unit will typically reduce supercharger speed, resulting in lower boost pressure and reduced load on the supercharger system. This pulley is manufactured by ATI Performance Products, a trusted name in high-performance pulleys, dampers, and drivetrain components for racing and street applications.
