    Maximize Dragstrip Performance with Quick Fuel Q-Series Carburetors

    Quick Fuel Q-Series Carburetors are the ultimate high-performance upgrade for bracket racers and weekend drag warriors seeking unbeatable throttle response and tuning flexibility.Built for precision and power at the track, Q-Series carburetors feature a lightweight aluminum main body with recessed air bleeds for smoother airflow and die-cast venturis machined for exceptional throttle response. Designed to handle hard launches, they include notched floats and secondary jet extensions to maintain fuel control under high g-forces. Billet metering blocks deliver a consistent fuel curve, while rugged throttle bodies enhance longevity. For racers adjusting on the fly, models with mechanical secondaries include the QuickLink system for fast secondary tuning. Available in configurations for gasoline, methanol, and E85—plus compatibility with forced induction and both vacuum and mechanical secondaries—the Q-Series is Quick Fuel’s most versatile drag racing carburetor lineup.
