The Edelbrock Supercharger System part 1538 is designed for your 2009 - 14 5.7L HEMI Dodge Ram Truck and produces 439 RWHP and 444 RWTQ. 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.
