To combat the g's experienced during hard launches and hard corners, Q-Series carbs are equipped with notched floats and secondary jet extensions. The high-flow aluminum main body isn't just lightweight, but it also 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. For those days when track conditions vary from one pass to the next, QFT's QuickLink system makes adjusting the secondaries easy on models equipped with mechanical secondaries. The Q-Series is our most comprehensive line of carburetors, with applications available for use with gasoline, methanol, and E85 fuels, forced induction, drag race, circle track, and comes in both vacuum and mechanical secondary models. โ€ขLightweight aluminum main body โ€ขVacuum and mechanical secondary models available โ€ขAluminum fuel bowls with dual sight glass windows โ€ขBillet metering blocks with 4-corner idle system โ€ขChangeable idle feed and power valve channel restrictions โ€ขBillet aluminum throttle body provides exceptional precision and strength โ€ขPTFE coated and sealed shafts
