ATI Performance Products ATI916227 Supercharger Pulley 9.17" 8-Rib Serpentine

The ATI Performance Products 916227 is a high-performance serpentine supercharger pulley designed to increase boost pressure and power output on LSA and LT4 supercharged engines. This precision-engineered crankshaft pulley features an overdrive design that spins the supercharger faster than stock, delivering more boost without the belt slippage issues common with smaller supercharger pulleys.

Key Features:

• 9.170-inch outside diameter for optimal supercharger speed
• 8-rib serpentine design for improved belt grip and reduced slippage
• 17% overdrive on LSA applications (2009-2015 CTS-V, 2012-2015 Camaro ZL1)
• 15% overdrive on LT4 applications (2016+ CTS-V, Camaro ZL1)
• Constructed from durable steel with black oxide finish
• Includes mounting hardware for easy installation
• Designed for use with ATI Super Damper harmonic balancers

This pulley is specifically engineered to work with ATI Super Damper models and provides a reliable method to increase boost pressure while maintaining belt integrity. The larger diameter crankshaft pulley accelerates the supercharger more effectively than reducing the supercharger pulley size alone, making it an excellent upgrade for enthusiasts seeking additional power from their forced induction setup.
