QFX Carburetor - 1050CFM Drag Race 3-Circuit

The QFX Carburetor - 1050CFM Drag Race 3-Circuit from Quick Fuel Technology is purpose-built for serious drag racing competitors and high-performance street/strip engines demanding maximum fuel delivery and tuning flexibility. This 1050 CFM four-barrel carburetor is engineered for engines that require uncompromising air and fuel metering in bracket racing, bracket drag events, and dedicated performance applications where consistency and power matter. Whether you're running a small-block or big-block combination, the QFX delivers the airflow capacity and circuit architecture needed to dominate the quarter-mile.

Quick Fuel's three-circuit design separates idle, cruise, and wide-open-throttle functions into independent pathways, eliminating cross-contamination and allowing precise jetting for each load condition. The 1050 CFM capacity ensures sufficient fuel atomization and distribution across the full RPM range without restricting airflow on high-displacement or boosted engines. Aluminum construction and vacuum-secondary operation provide weight savings and responsive throttle control, while the 3-circuit topology enables fine-tuning of bottom-end response and top-end power delivery through individual adjustment of idle mixture, transfer slot timing, and main metering circuits—critical for dial-in precision in competitive environments.

Serious drag racers, bracket competitors, and performance engine builders who require bulletproof fuel delivery and tuning control benefit most from this carburetor. Installation on compatible four-barrel intakes is straightforward; standard carburetor adapter rings and fuel line connections apply. Proper jetting selection based on your engine displacement, boost level (if applicable), and track altitude ensures optimal EFT (elapsed time) consistency and eliminates bog or hesitation off the line—essential for trophy-winning performances and dependable competition results.
