Quick Fuel Q-Series 500 CFM 2 BBL Carburetor - Circle Track - Gasoline

PROFORM(R) High-Flow Main Body - Larger sizes are secondary hard tool machined to exacting specifications to provide "real world" venturi/throttle bore combination, for throttle response and maximum wide open air flow. Screw-in air bleeds enable fine tuning of both the idle and high speed systems. Billet Metering Blocks - CNC Machined w/ 4-stage emulsion provide more precise fuel metering, improved throttle response and a more uniform fuel performance curve. Billet Throttle Body - QFT(R) throttle bodies CNC machined to exacting tolerances and provide exceptional strength. Slabbed Teflon(R) coated throttle shafts are assembled with Teflon(R) ribbon bearings, low-profile button head throttle plate screws results in maximin air flow with minimal throttle effort. Adjustable Secondaries - All mechanical secondary carburetors have an adjustable secondary idle speed bracket. This allows fine tuning of the secondary throttle position for improved idle quality. See page 29 for Adjustable Secondary Cam Bracket. Vacuum secondary carburetors feature QFT(R)'s billet adjustable vacuum secondary diaphragm housing. QFT(R) Fuel Bowl - All new for 2006, QFT(R)'s aluminum fuel bowl. This new die cast piece combines strength with weight reduction. Using conventional hardware and service components the QFT(R)'s aluminum fuel bowl features dual threaded fuel inlets, dual sight glass for convenient float level setting. An additional 2 threads of fuel bowl screw engagement reduces the possibility of striping threads out of the main body, and all too common problem. Dedicated for specific applications ensure optimum carburetor performance characteristics without having to purchase additional upgrade components.

Innovators in fuel systems is more than just a by-line. Quick Fuel Technology, since it's inception in 1998, has grown exponentially in its 11 years of business culminating into the benchmark by which performance carburetors are measured. The growth and success of Quick Fuel Technology is attributed to the strength and determination of its staff.

Notice - Due to the natural color variations of the dichromate plating process, the plating color may vary from casting to casting (within a carburetor) and from carburetor to carburetor. This is considered normal and is not a cosmetic defect. If you desire a carburetor with no color variation, please shop our black and shiny finish carburetors.

Over the years, Quick Fuel Technology has made considerable strides to become a stand-alone carburetor manufacturer. This increase in efficiency and capability has allowed us to continuously upgrade our products while keeping the prices low. In 2005, Quick Fuel Technology introduced its Super Street line of carburetors. This application-specific line catered to the enthusiast that wanted the best carburetor for the money while refusing to compromise street manners. Drawing from our race track experience we employed many features that were normally found on much pricier race carburetors, yet ours is generally half the price! In 2009, Quick Fuel Technology launched the QFX-Series. This design incorporates significant race engineered main body upgrades. Each carburetor is individually hand-assembled and engine tested. There simply is not a better carburetor for your money. 2010 saw the introduction of two new carburetor series from QFT - The RaceQ is the ultimate small flange drag race carburetor and packed with features that are sure to take your package to the next level. The Hot Rod series carburetor is our answer to the needs of street machines everywhere - from muscle cars to street rods, the HR Series is the most affordable and tunable carburetor on the market today. Keeping true to our motto, we look to the future and constantly seek the next innovation. With our past experience and race-track development we continue our pursuit of horsepower and efficiency.
