    Quick Fuel Technology FX-4700 Details

    Serious drag racing demand a serious drag racing carburetor, and the QFX-Series stands as the flagship model in QFT's lineup. Raised air horns improve entry angle into the venturi while ensuring undisrupted flow over the air bleeds. Annular boosters with CNC-machined billet aluminum inserts provide increased air flow, a stronger signal, and less turbulence. QFX carbs offer unparalleled fuel atomization with annular boosters specific for either gas, methanol, or E85 fuels. Five-emulsion billet metering blocks and four-corner idle circuits offer flexible tunability that today's high-horsepower engines demand. To cover a broad range of applications, methanol- and E85-compatible models, as well as two- and three-circuit fuel systems, are available. Ready to run out of the box, the QFX-Series carburetor will help you get to the winner's circle.

  • QFX aluminum main body w/raised venturi
  • Billet aluminum metering blocks with screw in restrictions
  • Aluminum fuel bowls with dual sight windows and fuel inlets
  • Nitrophyl® Floats (notched rear) and jet extensions
  • Viton .130" Needles and Seats
  • Billet Aluminum annular booster inserts
  • QuickLink™ adjustable secondary opening adjustment
  • Hand assembled and engine tested
