The Edelbrock supercharger Stage 1 Street system part #1590 compatible with 2008-13 Corvette increases the performance of your LS3 engine to 554 horsepower and 515 ft-lbs of torque to the rear wheels. 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. Keeping the air cool is a high-capacity air-to-water intercooler and low-temp heat exchanger. The Edelbrock #1590 system is 50-state emissions legal. The supplied tune is compatible with completely stock vehicles with the exception of a cat-back exhaust.
