Developed and designed by racing experts, the Edelbrock Supercharger Bypass Valves are premium aftermarket replacement units used in a wide variety of vehicles, including supercharger cars experiencing parasitic loss during non-boost or low-throttle driving. These losses affect the power and efficiency of a supercharged engine when used in city driving.

During slow, non-boost driving, this Supercharger Bypass Valve will reduce NOX engine emissions and allow your supercharger to operate at a cooler temperature. It helps your engine operate more efficiently with vastly improved gas mileage. And this is done by circulating compressed air back to the inlet via a shorter and less restrictive path for improved airflow. This bypass valve is easy to install as a replacement for your defective one and requires no drilling or modification.

Founded in 1938 by Vic Edelbrock Sr., the company was borne out of his desire to increase the performance of his very own 1932 Ford Roadster, designing a new intake manifold that would soon catch the attention of his friends and fellow drivers. From his humble garage, Edelbrock Sr. would soon become one of the most sought-after performance replacement automotive manufacturers in history. With his legacy carried on by his son Vic Jr. and a trusty team of talented mechanics and engineers, Edelbrock soon developed parts for racing that were commercially unavailable due to the sanctions imposed during the war.
