Gen III/IV LS Cathedral Port Hellcat Supercharger Adapter

This is a set of adapter plates to bolt a hellcat supercharger onto a Gen III/IV LS based GM engine with cathedral port heads. This will NOT fit on a Gen V LT Based engine. This also will NOT fit on a gen IV with rectangle port heads. This kit uses Gen V LT intake seals on the hellcat side of the adapter, and truck style cathedral port seals on the cylinder head side.

The Kit includes

• 2 adapter plates.
• 10 bolts to attach the adapter plates to the engine
• 1 set of 8x seals to seal the adapters to the supercharger.
• 1 set of truck style cathedral port seals

Things needed that the kit does not include

• DJTuning Griptec Pulley hub with LSA spacing.
• Griptec Pulley
• Optional: LSA serpentine system. See these instructions from Chevrolet for part numbers and installation LSA Drive
• Electronics to control the supercharger BPV. Options below
  
  • Standalone DJTuning Hellcat Bypass Valve Controller
  • Standalone Hellcat Smoothboost controller
    
  • We do not recommend the solid state relay option as others have tried. No long term reliability testing has been performed to validate this option as viable.
• Wiring to connect the TMAP sensor
  
  • Connector Housing: TE Connectivity 2050052-1
  • Connector Pins: 4x TE Connectivity 1-968849-1
    
  • Connector Wire Seal: 4x TE Connectivity 828904-1
• Wiring to connect the throttlebody
