Supercharger Carburetors

750 CFM Four Barrel Carburetor

PART #: 0-80573S

UPC #: 090127467190

Emission Control Number 3

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 vacuum, which has no bearing on the engine load.
