This is a Kenne Bell Liquid Cooled Supercharger System with a Mammoth 4.7LC Twin Screw head unit and 8 rib pulley setup for the 2015-2020 Challenger/Charger Hellcat which can get you at least +370 of rear wheel horsepower on 15-30 psi of boost using 93 octane gas, depending on your custom tuning! This is the tuner kit which will require a custom tune done locally after you install the kit, and does not include a fuel system, programmer, or tuning. Photos are for reference only, all standard kits are satin manifolds with black supercharger and drive unless otherwise mentioned in the details.

NOTE: This kit requires a larger hood for clearance.

These supercharger kits are the most complete available, including everything needed for installation. This includes all mounting brackets for the blower, pullies, belts, intercooler, all the tubing, piping, fittings and clamps and even oil for the self contained lubricating system. You do not need to make any major modifications or purchase special tools or other parts. Many customers install in their garage or driveway over a weekend.

KENNE BELL HELLCAT HEMI 6.2L 2015-2020 boost pully ratio

That is why our supercharger kit upgrades are unquestionably the Biggest, Baddest, Most Powerful and Coolest Billet Rear Inlet PD Hemi Kits. No other supercharger can match the size, lower parasitic loss, higher boost/cfm and cooler air charge temps of the precision Liquid Cooled billet Kenne Bell 4×6 lobe rotor Twin Screw supercharger. This isn’t some undersized 2L front inlet with a lesser cast aluminum case. The proven Kenne Bell Rear Inlet Concept includes huge minimum restriction inlet systems with a 1500HP ultra efficient intercooler, manifolds and the industry’s largest throttle bodies (170mm and Dual 106mm). These record breaking Hemi Mammoth and BIGUN systems have dominated the street, tracks and dynos since 2008, and are now further refined to support the added efficiency of the Hellcat 6.2. To guarantee maximum HP from the supercharger, we engineered two huge inlet systems (Mammoth and BIGUN) with equally large intercooler, manifolds and matching throttle bodies (up to 3800 cfm). Then there’s our exclusive Patented Liquid Cooling that allows our superchargers to rev higher and produce more boost and HP at cooler temps than our competition without rotor scuffing. This kit simply “has it all” including quick easy supercharger upgrading and room to grow.
