The Carburetor Flow Meter allows you to quickly dial in multiple carburetors or throttle bodies. It provides an exact, readable indication of airflow through the carburetors or throttle bodies. The sensitivity and accuracy of the Flow Meter is much greater than any other type of synchro tool or gauge. Carburetor Flow Meters can be used to check the air flow at low and high RPM on down draft and side draft engines.

Kit includes two adapters. The small adapter is ideal for all velocity stacks and intake bores of 1 5/8" to 2 1/8" (40 to 50mm Diameter) The large adapter fits approximately 2 1/2" (56 to 65mm Diameter).
