Edelbrock part #15420 UNIVERSAL supercharger system for street rods and muscle cars with Gen IV GM LS3/L92 engines with RECTANGULAR port cylinder heads. The part #15420 comes with a Camaro/GTO (GEN IV 1998-02) Belt Offset. These supercharger systems are designed to deliver maximum low end torque and great drivability. Edelbrock systems are 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. These systems require the use of a universal heat exchanger. System part #15420 does NOT include handheld tuner. Call for custom configurations.
