BLOWER CARBURETOR 600CFM MODEL 4150
HOLLEY 0-80592S

600 CFM Four Barrel Carburetor SHINY FINISH

These Carburetors that are intended for use with superchargers, and have a unique capability that allows their power Valves to reference the intake Manifold vacuum below the supercharger. This allows the power valve to operate as 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. Specifically Designed for Use on Roots Style Blown Engines; Model 4150; Shiny Finish; Manual Choke; Mechanical Secondary Double Pumper
