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

    I love them but pockets tear easily
    Size: 34, Color: #01black
    I love them. They look nice and they are comfortable. I bought a total of three and they're all I wear in the summer. Unfortunately the strap pockets wear out easily. On my left pocket I store a ridge wallet and my keys. For two of my most worn pair, the strap tore up to where it no longer holds the pocket closed properly. On one of those in the same pocket, a hole ended up torn in the corner. The third one I had to throw out after it shrunk after being washed improperly (can't wash them like I did my previous shorts which I washed the same way as the rest of my clothes). I think I'll continue to wear them, maybe even buy one more, until I find something better.

    Pocket and ability to hook my speaker to
    Size: 32, Color: Black, Size: 32, Color: Black
    I can't believe how comfortable they are and I'm very happy with all the pockets in the shorts. I bought the black as it my favorite color but will definitely be ordering all the colors available as they can be used as dress shorts.
