The Edelbrock Universal Supercharger System part # 15480 is designed for street rods and muscle cars with LS2 cathedral port cylinder heads and a Truck (88mm Throttle Body) belt offset. Edelbrock E-Force system is designed to provide instant and reliable horsepower with low boost for minimum stress on the engine. Its compact design fits under the stock hood on most applications and complements the clean look of any engine compartment. This system requires the use of a universal heat exchanger (sold separately). 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. This kit DOES NOT INCLUDE A TUNE, A CUSTOM TUNE MUST BE USED, NOT AVALIBLE THROUGH EDELBROCK.
