q-series carBureTors
• High-flow main body, with screw- in bleeds.
• Secondary idle-speed adjustment. Notched secondary floats and jet extensions (drag race only carb).
• Molded wedge floats in circle track carbs. QFT Billet Adjustable vacuum secondary housing system.
qfx series carBs
• Features an all new die-cast alumi- num main body with a lengthened venturi section.
• Red anodized billet aluminum CNC- machined metering blocks feature a
3-circuit metering, changeable emulsion, idle feed and feed discharge.
• Die-cast aluminum large capacity fuel bowls with a “Fuel Chute” are designed to flow incoming fuel to the bottom of the fuel bowl, they have dual site glass holes for
float level adjustment, dual threaded fuel inlets and light- weight characteristics.

race q series
• Features a high-flow main body and includes either down-leg or annular boosters, screw-in idle, high-speed
air bleeds, accelerator pump discharge nozzles, and a blended venturi area. CNC-machined billet metering blocks feature a 4-stage emulsion, improved
throttle response and give a more
uniform fuel performance curve.

slayer series carBureTors
• Features an aluminum casted, tumble-polished finish.
• New CNC machined centers and
unique design that utilizes a second-
ary metering plate with changeable jets eliminates the costly secondary metering block.
Marine carBs
• The M-Series features billet-style metering blocks and throttle bodies for more precise performance
and exceptional strength.
Black DiaMonD carBureTors
• Features a unique PTFE coating
that provides a highly durable satin black finish that is impact and scratch- resistant and impervious to under hood chemicals.
