Description
Carburetor Power Valve; For Use With Holley Carburetors; Single Stage High Flow; 3.5 Inch of Mercury; With Gasket
Holley Carburetors that are intended for use with superchargers, have a unique capability that allows their power valves to reference the intake manifold vacuum below the supercharger. This allows the power valve to operates it should, based off intake manifold vacuum. A power valve provides further enrichment to the main metering system under load & low vacuum conditions. Without this external referencing, the power valve would be reading the supercharger boost pressure, which has no bearing on the engine load
