Enhance performance with precise vacuum referencing for supercharged engines.
The Holley Carburetor Power Valve is designed specifically for use with Holley carburetors that operate in supercharged environments. This power valve features a single stage standard flow and is calibrated to reference the intake manifold vacuum below the supercharger, ensuring accurate performance under varying load conditions. By providing additional enrichment to the main metering system during low vacuum situations, it optimizes fuel delivery and engine efficiency.
Without the external referencing capability, the power valve would inaccurately read supercharger boost pressure, which does not reflect the actual engine load. This unique design allows for improved engine response and performance, particularly in demanding driving conditions. The power valve is rated at 8.5 inches of mercury and includes a gasket for easy installation.
This product is essential for those looking to maximize the performance of their Holley carburetors in supercharged applications. Its technical specifications and features make it a reliable choice for enhancing engine performance.
