HR-Series Carburetor 750 CFM 2x4 Supercharger
These carbs include boost-referenced power valves, and 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 to lessen the possibility of fuel leaking onto the intake.
QFT's 2x4 blower carbs feature shortened throttle levers for clearance. The QFT engineers added an external vacuum reference tube 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.
