In circle track classes that mandate two-barrel carburetors, customizing a street carburetor has been the norm for decades. Not anymore. Newly designed to meet the unique demands of circle track racing, Quick Fuel Technology’s XP-Series carb offers the performance benefits of a custom carb in an affordable, class-legal, ready-to-run package that costs less than making each required modification separately.

XP-Series carbs boast a high-flow aluminum main body that places the venturi over the throttle-body assembly. To further increase airflow, QFT put the air horn over the venturi, removed the choke tower, and precision profiled the air inlet transition. The result: improved horsepower and throttle response. Available in 500- and 600-cfm sizes, the XP-Series has set the bar for two-barrel circle track carbs.

  • Turnkey two-barrel carb ready for the circle track.
  • High-flow aluminum main body.
  • Roller bearing seals improve throttle response and reduce shaft wear.
  • Available in 500- and 600-cfm sizes.
  • Fuel type: gas.
