Overview:

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

    SUPER great denim-should last for years!
    Size: 30, Color: Truest Blue
    lI don't know if these will be flattering on me, but I LOVE THEM. They're hip and cool and I will wear them although I am 65. Would look best with shorter shirts, but of course, not showing belly. A slim young woman would "kill" this look. Denim is heavy duty and all hardware top class. The ad said to size down, but I ordered my regular size. The waist is a little tight on me, but the barrel legs are loose and hang nicely. Definitely something I will wear with platform ankle boots or sneakers. I anticipate people will absolutely love them (younger folk) where people my age, may say hmmm because they are a statement piece.
