DMS High Flow Billet LT4 Supercharger Lid

Lid weight: 6.7 pounds

DMS teamed up with Verus engineering to design and manufacture the ultimate LT4 supercharger lid. We started with a GM cad model and analyzed the flow characteristics. From there we designed a airflow path to disturbed air to each runner as equally as possible. The inside of the lid is radius matched with the edge of the supercharger housing making the airflow a natural event. These are machined from a solid chunk of 6061 aluminum using the Verus engineering DMG 5 axis CNC machine. They're strong, light and designed to perform while adding a bit more supercharger whine. During our testing on a bone stock 2018 CTS-V we picked up an average of 20hp across the range. 

• Powder coating will be available soon. 

• Will not work with CTS-V strut bar without spacers. 

• New lid hardware included. Reuses GM green O-ring around the perimeter.
