The Edelbrock Supercharger System part #15343 is a Pro-Tuner System that delivers excellent horsepower and torque for your 2011-14 5.7L HEMI Chrysler 300, Dodge Charger or Challenger. The part #15343 gives you all the essential components needed to build a custom supercharged race setup. This gives you the flexibility in pulley selection, cold air intake, and more. The part #15343 is for competition racing use ONLY! Featuring a unique design with minimal components makes it possible to fit an Edelbrock supercharger under the stock hood. The core of each system is the Eaton Gen VI 2300 Supercharger rotating assembly with a four-lobe design with 160 degrees of twist for maximum flow, minimum temperature rise and quiet operation for excellent drivability. We also designed our superchargers with an integrated bypass valve to help eliminate parasitic loss under light throttle, improving mileage potential. Our unique and efficient inlet configuration results in a shorter, less restrictive intake path for improved airflow, without the need for a jack-shaft. Keeping the air cool is a high-capacity air-to-water intercooler and low-temp heat exchanger. Customer MUST purchase a heat exchanger SEPARATELY. For safety, the Edelbrock-supplied program will retain the factory vehicle speed limiter setting. This unit is NOT supplied with a Programmer. Supercharger systems without tuners are not eligible for supplemental warranty. Supercharger systems sold without tuners are only emissions legal when used with the correct Edelbrock program.
