Protect your engine and optimize performance with the ATI Super Damper harmonic balancer (MPN ATI917993), specifically engineered for the 1.6L Mini Cooper S. Unlike factory rubber-dampened pulleys that degrade over time, the ATI Super Damper is designed to eliminate torsional crankshaft vibrations across the entire RPM range, ensuring engine longevity and smoother operation in high-performance applications.

This 5.74-inch aluminum damper features a 6-groove pulley design and a 2% overdrive (OD) ratio. The slight overdrive increases the rotational speed of the supercharger, providing a measurable performance gain while the lightweight aluminum construction reduces rotating mass compared to heavier steel alternatives. It is a direct-fit, 1-piece unit that replaces the failure-prone OE crank pulley.
