The Edelbrock Universal Supercharger System part #15470 is designed for street rods and muscle cars with cathedral port cylinder heads and a Camaro/GTO LS2 (Gen IV 1998-02) belt offset. Edelbrock 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. The core of this system is the Eaton Gen VI 2300 TVS 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. This kit DOES NOT INCLUDE A TUNE, A CUSTOM TUNE MUST BE USED, NOT AVAILABLE THROUGH EDELBROCK.
