Q-Series carburetors are purpose-built for the dragstrip. Equipped with notched floats & secondary jet extensions. High-flow aluminum main body is lightweight & features recessed air bleed cavities for improved air flow. Die-cast venturi are machined to exacting tolerances for outstanding throttle response. Billet metering blocks ensure a uniform fuel curve, while throttle-bodies enhance durability. QFT QuickLink system makes adjusting the secondaries easy on models equipped with mechanical secondaries.
