Kenne Bell 2.8L Supercharger System 5.7L HEMI

The Kenne Bell Mammoth 2.8L Supercharger System is a comprehensive, intercooled upgrade designed to significantly boost the performance of 2011-2019 Dodge Challenger and Charger R/T models equipped with the 5.7L HEMI engine. This kit features the Mammoth 2.8L Twin Screw head unit, known for its efficiency and immediate power delivery, paired with a stock 6-rib pulley setup. Kenne Bell claims this system can achieve an impressive 475 rear wheel horsepower with only 8 psi of boost when using 91 octane gasoline. This complete kit includes all necessary components for installation, such as a Kenne Bell Boost-A-Pump fuel pump booster to ensure adequate fuel delivery, high-flow 50lb fuel injectors, and a user-friendly handheld programmer pre-loaded with a specific tune. The included "bolt-on and drive" tune is optimized for vehicles in stock condition or those modified only with a cat-back exhaust. For vehicles with more extensive modifications like headers, mid-pipes, or camshafts, a "TUNER" kit (TS7501-2.8TUN) is recommended. The system's design emphasizes efficient air intake, drawing cool, dense air from a unique inlet filter positioned behind the front bumper, similar to classic HEMI scoops. It boasts a "Huge rear inlet design" (1850 cfm) compared to smaller, more restrictive front inlets. The intercooler is also a key feature, described as "EXCLUSIVE HI DENSITY INTERCOOLER" with 20% larger capacity and 30% more cooling rows and fins for enhanced cooling efficiency. The kit is 50 State CARB Legal and includes a patented billet external spring bypass valve, a 4.5" Cold Air Kit, and all mounting brackets, pulleys, belts, tubing, and fittings required. It also includes self-contained lubrication oil for the supercharger.
