Quick Fuel 1050 CFM Annular Boosters

For competitive classes where every last hundredth of a second counts, Race Q-Series carburetors offer excellent performance, consistency, and tunability. Vacuum-drawn die-cast aluminum main bodies eliminate porosity and yield extremely precise tolerances. Scalloped, symmetrical throttle bore openings work in concert with recessed air bleed cavities to minimize flow restrictions, and specially contoured venturi provide a broad operating range. For added versatility, Race Q carbs utilize a dual-pattern billet throttle-body, making them compatible with both 4150- and 4500-style flanges. All Race Q carburetors feature billet metering blocks with five-stage changeable emulsions, as well as, throttle bodies with roller bearing seals to provide smoother operation, less wear on shaft, and longer life.
