The Edelbrock E-Force Stage 1 Street supercharger system (part #15880) for 2011-14 Mustangs increases the performance of your Coyote 5.0L 4V engine to 559 horsepower and 503 ft-lbs of torque at the crank when used with an Edelbrock tune (kit supplied without a programmer). The core of the system is the Eaton Gen VI 2300 TVS rotating assembly, with a four-lobe design and 160 degrees of twist for maximum flow, minimum temperature rise and quiet operation for excellent drivability. The supercharger has an integrated bypass valve to help eliminate parasitic loss under light throttle, and its efficient inlet configuration gives a shorter, less restrictive intake path without the need for a jackshaft. A high-capacity air-to-water intercooler and low-temp heat exchanger keep the air cool. Handheld programmer not included.
