Edelbrock part #15426 Universal Edelbrock Supercharger System for use with GM Performance?s LS3 (#19244805) E-Rod emissions-legal Gen IV small-block crate engine with Corvette belt offset. This system includes all of the necessary components to increase the performance of these engines, while maintaining the E-Rod emissions-legal status. This system is ideal for use 1995 and earlier vehicles and kit cars that require emissions testing. The supercharger housing features 12? long runners for 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. 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.
