Carbs & Accessories : 950 HP HOLLEY REFERENCED CARB

950 Holley 4150 HP referenced carburetor:

These carburetors 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.
