The Edelbrock Supercharger System part #1535 is designed for your 2011-14 6.4L HEMI Chrysler 300, Dodge Charger or Challenger. The part #1535 kit made 551 RWHP and 526 RWTQ. 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 d esign 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.
