Enhance performance with a reliable power valve for Holley carburetors.
The Holley Carburetor Power Valve is designed specifically for use with Holley carburetors that are equipped with superchargers. This power valve features a single stage standard flow and operates at a pressure of 5.5 inches of mercury. Its unique design allows it to reference the intake manifold vacuum below the supercharger, ensuring optimal performance under varying load conditions.
This power valve plays a critical role in enriching the main metering system during low vacuum situations, providing necessary fuel delivery when the engine is under load. Without the external referencing capability, the power valve would inaccurately read supercharger boost pressure, which does not reflect the actual engine load. The inclusion of a gasket ensures a secure and leak-free installation, making it a practical choice for enhancing engine performance.
