Viper GTS Roe Racing 2.4l supercharger pulley and hub

Description

This hub allows the use of a Whipple, 4 bolt pulley on the Roe Racing 2.4l Viper GTS supercharger system, allowing for different size pulleys (Roe pulleys are about impossible to find). These pulleys use an 8 rib belt, so the 8th rib is unused on the Vipers 7 rib belt. This set includes a 2.500 inch pulley (tiles 9-11 psi depending on set up and elevation), 4 stainless 1/4-28 bolts and the Roe hub adapter.
