The Edelbrock E-Force Supercharger Stage 2 Track System part # 157320 is for use with 2015-17 Chevy Corvette ZO6 LT4 engine applications. 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. Keeping the air cool is a high capacity air to water intercooler and low temp heat exchanger. This kit DOES NOT INCLUDE A TUNE, A CUSTOM TUNE MUST BE USED, NOT AVALIBLE THROUGH EDELBROCK. Finally... the Edelbrock E-Force Supercharger system is not just a performance upgrade, it also has great looks! The supercharger assembly and aluminum coil covers (on most applications) are powder coated for durability and provide a unique appearance that will give any engine compartment a custom look.
