Product Details

XCTC Series


The XCTC Series is ATM Innovation’s most affordable "circle track" race carb yet it has all the features of its high-end race carburetors but is based on quality ATM™ die cast aluminum carb bodies, metering blocks and throttle plates. This cost savings over billet components doesn’t hamper performance, and you still get ATM's™ all aluminum dual inlet, dual site-window fuel bowls, changeable idle and high-speed air bleeds and changeable idle feed and power valve channel restrictions providing endless tuning capabilities. These carburetors are precisely calibrated at the factory and are “race-ready” out of the box requiring minor “trim” adjustments for atmospheric conditions and your individual race combination. They are available in 650, 750, 850, 950 and 1050 CFM sizes for 4150-style flange manifolds.

  • 4-corner idle adjustment
