Q-Series Carburetor 650 CFM DRAG 2X4 Supercharger. Quick Fuel Technology's ready-to-run 2x4 Blower Carburetors will deliver the air and fuel your engine needs to make race-winning power. QFT's 2x4 blower carbs feature shortened throttle levers for clearance. An external vacuum reference tube has been added for the power valve to connect to the intake manifold with a hose. This allows the power valve to see only positive pressure at Wide Open Throttle, eliminating the possibility of the power valve closing if the supercharger starts to "out run" the carb.

The specially designed throttle body features built in channels to guide excess fuel from the top of the throttle plates around the throttle shafts and back into the intake manifold. This lessens the possibility of the fuel build up running out the throttle shafts onto the hot intake manifold.
