USED FOR IMPROVED BELT WRAP ON SALEEN SUPERCHARGERS

This is an excellent method of improving belt wrap to help prevent belt slip. These water pump pulleys are OEM quality and easy to install. They are slightly larger than the factory Ford waterpump pulley. The larger diameter will allow your supercharger belt to wrap better around the supercharger pulley which will result in less slip and possible more boost. Typically a new belt is not needed when installing this oversize waterpump pulley.
