    For serious drag race applications, all-aluminum Quick Fuel QFX Carburetors were developed with the racer in mind. A distinctive lightweight main body with lengthened venturi offers more mid-range torque, which is great for both throttle stop and bracket racing. Heads-up racers benefit from the raised intermediate system that provides a stronger signal and better flow to the booster venturi.

    QFX Carbs come with all-new billet metering blocks designed for each fuel type: gas, methanol, and E85. Strong and reliable cast aluminum fuel bowls have dual threaded fuel inlets & dual sight glass for simple float level setting. Dedicated floats ensure maximum performance without additional upgrades. CNC'd billet aluminum booster inserts provide refined air entry/exit for improved fuel emulsion resulting in superior combustion (gas carbs have 12 discharge holes compared to the standard 8).

    Features:
  • Range: 525 to 1450 cfm (some carburetors available in a kit*)
  • Purpose-built for drag racing
  • Hand assembled & engine tested
  • Lightweight aluminum construction
  • Main body with extended venturi for greater mid-range torque
  • Billet metering blocks specific to fuel
  • Cast aluminum fuel bowls
  • Easy float level adjustment
  • Annular boosters
  • CNC-machined billet aluminum booster inserts provide enhanced air entry/exit, improved fuel emulsion, and superior combustion
  • External linkage with four links to choose the amount of primary throttle opening before the secondaries open: Moderate Progressive (25%), Medium Progressive (40%), Full Progressive (50%), and 1:1
