The Edelbrock E-Force Supercharger Stage 2 system part # 15856 for 2005-09 Ford Mustang increases the performance of your 4.6L 3V engine to 529 horsepower and 494 ft/lbs. of torque at the crank. The core of this system is the Eaton Gen VI 2300 TVS 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 air flow, 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 #15856 supplied tune is intended for completely stock vehicles with the exception of a cat-back exhaust.
