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.
