Oversized Waterpump Pulley
Made from lightweight and durable anodized aluminum, the pulley is CNC'ed 8% larger than an SR20DET OEM water pump pulley. The increase in diameter elminates inertial cavitation which causes inefficient cooling and ultimately overheating. This application is excellent for those high revving track days where maximum cooling is a must. The pulley is designed for use with the stock belt size therefore no modification is needed.
