Specification
Description
The Holley Single-Stage Power Valve is a crucial component in the power enrichment circuit of Holley's performance carburetors. It utilizes engine vacuum to control its opening and closing rate, supplying additional fuel during heavy load or full power situations to eliminate hesitation and bogging. This ensures smooth power delivery without drivability concerns. The valve opens at 9.5 inches of mercury (Hg) and comes with a gasket for easy installation. Designed for standard flow applications, it enhances power enrichment and overall engine performance.
