750CFM Circle Track Carburetor

The PROFORM 750CFM Circle Track Carburetor (SKU PFM67215) is a purpose-built fuel delivery system engineered for high-performance circle track racing applications where reliable CFM metering and consistent throttle response are non-negotiable. Designed for operators who demand precision fuel atomization and repeatable performance lap after lap, this 750 CFM carb eliminates guesswork in fuel mixture calibration and supports competitive power delivery in purpose-built race engines. Circle track racing environments—from dirt ovals to paved short tracks—require carburetors that can handle rapid acceleration, sustained high RPM, and the thermal stress of continuous operation, making this PROFORM unit a trusted choice among serious racers.

The 750CFM Circle Track Carburetor features a square bore design with mechanical secondary operation and dual inlet configuration, delivering precise fuel metering across the entire RPM band without choke complexity. Its four-barrel design and aluminum construction anodized in black with tumble polish finish provide corrosion resistance while minimizing parasitic weight—a critical factor in circle track competition where every tenth of a pound affects acceleration and handling. The mechanical secondary system automatically opens based on throttle demand, ensuring progressive fuel delivery that prevents stumble on hard acceleration while maintaining lean-cruise efficiency, making tuning more intuitive for competitors focused on track time rather than carburetor mastery.

Racers competing in circle track series—dirt late models, stock cars, and other short-track divisions—benefit most from the PROFORM 750CFM unit's no-choke, all-weather readiness and mechanical simplicity, which translates to faster tuning between heats and consistent performance in variable track conditions. Installation requires standard carburetor mounting to a square-bore intake manifold; the dual inlet configuration accommodates fuel systems common in race vehicle builds. Weighing 9.25 lbs and measuring 11.4 x 7.6 x 13.5 inches, this carb integrates into most circle track engine bays while maintaining a compact footprint that preserves hood clearance and aerodynamic integrity on low-slung race platforms.
