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.QUICK FUEL,QUICK FUEL,ΓÇóQFX aluminum main body w/raised venturiQUICK FUEL,ΓÇóBillet aluminum metering blocks with screw in restrictionsQUICK FUEL,ΓÇóAluminum fuel bowls with dual sight windows and fuel inletsQUICK FUEL,ΓÇóNitrophyl (R) Floats (notched rear) and jet extensionsQUICK FUEL,ΓÇóViton .130" Needles and SeatsQUICK FUEL,ΓÇóBillet Aluminum annular booster insertsQUICK FUEL,ΓÇóQuickLink (TM) adjustable secondary opening adjustmentQUICK FUEL,ΓÇóHand assembled and engine tested
