QBDQ-650 - QUICKFUEL CARBY Q-SERIES BLACK DIAMOND 650 CFM SQUARE BORE DBL-PUMP

Q-Series Carburetor 650CFM Black Diamond

Ideally suited for bracket racers and weekend warriors alike,Q-Series carburetors are purpose-built for the dragstrip. To combat the g's experienced during hard launches,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.
Even a carburetor that performs great can still be an eyesore,but it doesn't have to be that way. Quick Fuel Technology's proprietary Black Diamond®coating offers excellent corrosion resistance as well as a durable finish that easily stands up to dirt and oil. In addition to great looks,the PTFE coating reduces fuel temperature by six percent for improved performance.
