FST Performance Billet X-treme Series Carburetors

FST Performance Billet X-treme Series carburetors are designed for the customer looking to gain an edge in their high performance application. Available with different CFM, secondary, fuel bowl, and finish options, they feature CNC-machined main bodies and high performance metering blocks—which have six stages of emulsion that offer a larger range of tunability, along with the ability to handle the varying demands of all current fuels, including methanol and ethanol.
