Description

New Quick Fuel FX-4714 - Quick Fuel QFX-Series Carburetors 1450 CFM 4500, 4-Barrel, Dominator Flange, 2.000 in. Venturi
These Quick Fuel QFX-Series carburetors feature an all-new die-cast aluminum main body, which has a lengthened venture
section for greater midrange torque and better airflow. The annular booster venturis are precision die-cast with CNC-machined
billet aluminum inserts, providing smoother and more refined air entry, a stronger vacuum signal, less turbulence, and improved
fuel emulsion for better combustion. The Quick Fuel QFX-Series carburetors use red anodized billet aluminum CNC-machined
metering blocks featuring 3-circuit metering (gasoline carburetors), changeable emulsion, idle feed, and intermediate bowl and
feed discharge. Next, the die-cast aluminum fuel bowl combines high strength with significant weight reduction. They feature
dual threaded fuel inlets and outlets and dual sight glass holes to easily set the float levels. The Quick Fuel QFX-Series
carburetors feature Quick Fuel's external linkage with four different links to select the amount of primary throttle opening before
the secondary's open: moderate progressive (25 percent), medium progressive (40 percent), full progressive (50 percent),
and 1:1
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.
