With an opening of 15.5 square inches, the supercharger inlet is designed for maximum flow to the 2650 TVS rotors. A series of adapters are used to mount different size throttle bodies to the Supercharger. Stage 1 kits use the factory air box and factory 80mm throttle body. Stage 1 kits include the Modular 90mm (M-90) adapter that accepts all throttle bodies that use the factory bolt pattern up to a 90mm bore size.
