The Edelbrock supercharger Stage 1 Street System part #1557 for 2015-17 Ford F-150 increases the performance of your 5.0L 4V engine to 533 horsepower and 482 ft-lbs of torque at the rear wheels. The core of this system is the Eaton Gen VI 2650 TVS rotating assembly with a four-lobe design with 170 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 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. The Edelbrock #1557 system is 50-state emissions legal. The supplied tune is intended for completely stock vehicles with the exception of a cat-back exhaust.
