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.Even a carburetor that performs great can still be an eyesore, but it doesn't have to be that way. Quick Fuel Technology's proprietary Black Diamond® coating offers excellent corrosion resistance as well as a durable finish that easily stands up to dirt and oil. In addition to great looks, the PTFE coating reduces fuel temperature by six percent for improved performance.ΓÇóQFX aluminum main body w/raised venturiΓÇóBillet aluminum metering blocks with screw in restrictionsΓÇóAluminum fuel bowls with dual sight windows and fuel inletsΓÇóNitrophyl® Floats (notched rear) and jet extensionsΓÇóViton .130" Needles and SeatsΓÇóBillet Aluminum annular booster insertsΓÇóQuickLink™ adjustable secondary opening adjustmentΓÇóHand assembled and engine tested
