BOWLING GREEN, KY – Quick Fuel Technology® (QFT™) has introduced a new series of circle track racing 2-BBL carburetors (Part # XP-4412) that are packed with features designed to make them competitive with the one-off custom-built carbs that cost hundreds of dollars more. Precise, black anodized billet metering blocks and throttle bodies are devoid of casting flaws and irregularities. A die-cast, lightweight aluminum main body has centered venturis for improved performance and better distribution. The choke tower has been eliminated and the inlet specially contoured for increased airflow as well. An anti-siphon check valve is installed in the main body to reduce pump pullover. The throttle body incorporates roller bearing seals that provide for smoother operation and less wear on the shaft. Specially designed straight leg boosters provide higher airflow (XP-4412-S only).
Like all QFT carbs, these new 2-BBL Circle Track Carburetors are infinitely tuneable with changeable air bleeds, emulsion bleeds and power valve channel restrictions. They are augmented with adjustable idle mixture screws. For those exacting and difficult race applications optional 3-circuit metering is also available. Rounding out the fuel handling duties is a dual inlet fuel bowl with -8 AN fittings. It is equipped with dual sight glass windows for easy float adjustment and a single wedge style circle track float.
QFT finished off these carbs with its proprietary Black Diamond® coating that provides enhanced corrosion protection and a 6% reduction in fuel temperature. Quick Fuel’s 2-BBL Circle Track Carbs are available for use with gas, methanol and E85 fuels. There are currently four carbs available – three 500cfm models with 1.375” venturis that are intended for classes with a “gage rule”. Part # XP-4412 is for gas, part # XP-4412-A is for methanol and part # XP-4412-E85 is for ethanol and E85 fuels. Part # XP-4412-S is a Sportsman version that flows more than 600cfm with a 1.450” venturi and is calibrated for gas.
