NEX Nitrous Oxide Kits

This Billet Hellcat Supercharger Lid replaces the upper supercharger lid on all Hellcat Superchargers for a quick and clean install. Nitrous and fuel are injected into each cylinder from inside of the supercharger lid, providing direct port style distribution. Systems come standard as a single stage with jetting for 100 to 300WHP. This lid is made from a solid piece of billet aluminum with 1/8NPT machined directly into the lid, which makes it easy to add a direct port water/methanol later on. This is the upgrade your Hellcat wants! The Billet Supercharger Lid for Hellcat/Demon applications replaces the factory supercharger lid for a quick and clean install. The improved airflow design of the lid ensures maximum flow and the placement of nitrous and water methanol passages provides huge increases in horsepower and torque. The spraybar-less nitrous system injects nitrous and fuel in line with the supercharger air discharge so the fuel / nitrous mixture is swept evenly to each runner. Injecting nitrous into this pre intercooled hot air discharge super-cools the air charge resulting in increased flow across the factory intercoolers for maximum power gains. As mentioned, this system is a 'spraybar-less' design, which means that the nitrous/fuel passages are CNC machined into the lid itself so the spray pattern is in the perfect location every time.
