LS Cathedral Port Supercharger Conversion Kit

The ICT Billet Hellcat Supercharger to LS Cathedral Head Adapter Kit provides a solution for integrating a Hellcat supercharger onto LS engines equipped with cathedral port cylinder heads. This allows for aggressive forced induction by utilizing Mopar's proven supercharger technology in conjunction with GM's LS platform. The kit is engineered to work seamlessly with a 2-belt LSA accessory drive system, featuring a billet conversion hub and a 3-inch 8-rib pulley to effectively mate the Hellcat supercharger to a standard LSA 8-rib belt setup, eliminating the need for cutting or fabrication. Constructed from 6061-T6 billet aluminum, this adapter kit is proudly made in Wichita, Kansas, USA. It includes essential components such as a throttle body adapter for a 4-bolt LS style connection, MAP sensor port plugs, a MAP 1/8" NPT port for GM sensor connection, and head-to-supercharger adapters with O-rings. Additionally, it comes with a supercharger hub and 3-inch 8-rib pulley, bolts for attaching the supercharger to the adapter plates, and an oil pressure sensor relocation adapter with a wire extension for valley cover mounting. For optimal performance and installation, the kit is designed to be used with specific LSA components, including an LSA crank balancer (ICT # BAL301) and an LS3 Corvette or LSA water pump (ICT # WAT101). Proper 8-rib supercharger belt tensioning and routing can be achieved with ICT's billet tensioner and idler bracket kit (ICT # 551189-LS01). For other accessories, the recommendation is Corvette -1 spacing, with compatible alternator and Saginaw power steering bracket options available (ICT # BKT-LS002-1), or an alternative kit for Type 2 power steering (ICT # 551521X-1).
