The airflow experts at Trick Flow have teamed up with Quick Fuel Technologies to produce four-barrel carburetors capable of feeding high-horsepower street and race engines.
This carburetor features a billet aluminum throttle body and metering blocks. Replaceable idle feed restrictors, power valve channel restrictions, and idle and high-speed air bleeds offer superior tunability. Other features include a 4-corner idle system, dual-sight glass 4500-style fuel bowls, and additional links to tune the secondary opening rate.
These carburetors feature a high-flow main body with a blended venture area to help smooth out airflow into the manifold. Trick Flow added screw-in idle air bleeds, high-speed air bleeds, and accelerator pump discharge nozzles for almost unlimited tunability. The CNC-machined billet metering blocks have 4-stage emulsion bleeds to provide more precise fuel metering, improve throttle response, and provide a more uniform fuel performance curve. Additional links to tune the secondary opening rate are included.
This Dominator-style carburetor features a new die-cast aluminum main body with a lengthened venturi section for greater midrange torque and better airflow. The annular booster venturis are precision die-cast with CNC-machined billet aluminum inserts. These provide a smoother and more refined air entry, stronger vacuum signal, less turbulence, and improved fuel emulsion for better combustion.
Other features include CNC-machined billet metering blocks with 3-circuit metering, changeable emulsion, idle feed, intermediate bowl, and feed discharge bleeds, and die-cast aluminum fuel bowls with dual sight glass holes. The external linkage comes with links for moderate progressive (25 percent), medium progressive (40 percent), full progressive (50 percent), and 1:1 primary throttle opening rates.
