• 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 #1581 system is 50-state emissions legal. The supplied tune is intended for completely stock vehicles with the exception of a cat-back exhaust.
