High Flow Main Body
The Q-series uses an all new QFT die cast aluminium main body, featuring recessed air bleed cavities, polished main body, and improved air flow. Venturi are die cast to exacting tolerances to provide a "Real World" venturi/throttle bore combination, for throttle response and maximum wide-open airflow. Screw-in air bleeds enable fine tuning of both the idle and high-speed systems. Q series carburetors weigh 4.5lbs less than the leading competition carburetor.
Billet Metering Blocks
CNC-Machined with 4-stage emulsion provides more precise fuel metering, improved throttle response and a more uniform fuel performance curve. Billet metering blocks feature changeable idle feed and power valve channel restrictions.
Billet Throttle Body
QFT throttle bodies are CNC-machined to exacting tolerances and provide exceptional strength. Slabbed Teflon coated throttle shafts are assembled with Teflon ribbon bearings, low-profile button head throttle plate screws, which result in maximum airflow with minimal throttle effort.
Adjustable Secondaries
All mechanical secondary carburetors have an adjustable secondary idle speed bracket. This allows for fine tuning of the secondary throttle position to produce improved idle quality.
All mechanical secondary carburetors feature a "Quick Link" system that alters the secondary opening rate by simply changing the secondary link. 40%, 60% or 1:1 opening rates are available. QFT's vacuum secondary carburetors feature QFT's adjustable "Quick Set" diaphragm housing.
QFT Fuel Bowl
QFT's aluminium fuel bowl is unique, combining strength with significant weight reduction. QFT's aluminium fuel bowls feature dual threaded fuel inlets and dual sight glass for convenient float level setting. Dedicated floats for specific applications ensure optimum carburetor performance characteristics without additional upgrade components.
QFT Colours
Unlike some other brands, QFT billet colours have specific meanings.
Red -> Petrol
Blue -> Alcohol
Green -> E85
Black -> RQ Race w/5 Emulsion Metering blocks
Custom colours for different fuels are available as special order items.
