Not anymore. Designed from the ground up to meet the unique demands of circle track racing, QFT's new XP-Series offers the performance benefits of a custom carburetor in an affordable, turnkey, class-legal package. At a bare minimum, modifying a standard street carburetor for circle track duty typically involves changing the throttle-plates, floats, and metering blocks. These custom modifications can easily exceed the cost of a turnkey QFT two-barrel carb while still lacking many of the key features that only a clean-sheet redesign can offer. A high-flow aluminum main body design centers the venturi over the throttle-body assembly. To further increase airflow, QFT centers the air horn over the venturi, removes the choke tower, and carefully profiles the air inlet transition. The result is enhanced airflow and fuel distribution, which improves throttle-response and horsepower. All XP-Series carburetors are equipped with roller bearing seals which provide smoother throttle response, less wear on shaft, and longer life. Available in 500- and 600 cfm sizes, the XP-Series sets a new standard in two-barrel circle track carbs.","brand":"Quick Fuel Technology","offers":[{"title":"Default Title","offer_id":50690348056891,"sku":"BJVK_XP-4412-A","price":972.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0942\/8438\/2523\/files\/tcxp4412_0618198.jpg?v=1761898961"},{"product_id":"650-cfm-4150-mechanical-secondaries-black-gasoline","title":"650 CFM - 4150 - Mechanical Secondaries - Black - Gasoline","description":"650 CFM - 4150 - Mechanical Secondaries - Black - Gasoline","brand":"Quick Fuel Technology","offers":[{"title":"Default Title","offer_id":50690349367611,"sku":"BJVK_M-650","price":1024.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0942\/8438\/2523\/files\/m-650.jpg?v=1761898994"},{"product_id":"750-cfm-4150-mechanical-secondaries-black-gasoline","title":"750 CFM - 4150 - Mechanical Secondaries - Black - Gasoline","description":"750 CFM - 4150 - Mechanical Secondaries - Black - Gasoline","brand":"Quick Fuel Technology","offers":[{"title":"Default Title","offer_id":50690351300923,"sku":"BJVK_M-750","price":1024.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0942\/8438\/2523\/files\/m-750.jpg?v=1761899047"},{"product_id":"750-cfm-4150-mechanical-secondaries-shiny-gasoline-1","title":"750 CFM - 4150 - Mechanical Secondaries - Shiny - Gasoline","description":"Ideally suited for bracket racers and weekend warriors alike, Q-Series carburetors are purpose-built for the dragstrip.

Since racing around a banked oval pushes fuel to the passenger side of the car, Q-Series circle track carburetors feature die-cast aluminum fuel bowls with internal baffles that eliminate slosh. The bowls also feature an integrated fuel chute that substantially reduces aeration, and directs fuel toward the main jet pickup area. To assist in flattening out the fuel curve, screw-in air bleeds enable fine-tuning of both the low- and high-speed systems, while a proprietary booster design enhances carb signal without restricting high-rpm airflow. Helping drivers put the power down is an adjustable QuickLink system that allows changing the opening rate of the secondaries to 40-, 60-, or 100 percent. Circle track Q-Series carbs are available in 6 different sizes ranging from 650-1,050 cfm for both gasoline and alcohol applications.
