750CFM Carburetor - Brawler SSR-Series

The Quick Fuel Technology 750 CFM Brawler SSR-Series Carburetor is a square-bore, 4-barrel fuel delivery system engineered for street-driven performance engines requiring consistent mid-to-high RPM fuel metering. This electric-choke equipped carburetor features mechanical secondary activation and dual inlet fuel supply, delivering the precise atomization curve needed for responsive throttle control and stable idle characteristics across varying ambient temperatures and load conditions.

Constructed from aluminum and finished in black anodized with tumble-polished accents, the Brawler SSR delivers 750 cubic feet per minute of air capacity—a specification that positions it at the upper range of carburetors suitable for naturally aspirated street engines in the 400–450 horsepower range. The square-bore design ensures compatibility with OEM and performance intake manifolds designed for this bore pattern. Mechanical secondary operation means fuel delivery increases proportionally to throttle demand without electronic intervention, simplifying tuning and eliminating dependency on external control modules—a proven advantage in high-vibration environments or when electrical systems are stressed.

This carburetor is specified for street enthusiasts, hot rod builders, and engine rebuilders seeking reliable fuel metering without modern-era complexity. The dual inlet fuel supply accommodates dual-feed fuel pump setups common in performance builds, while the electric choke simplifies cold-start procedures compared to manual choke designs. Weight of 9.52 lbs makes mounting straightforward on standard manifold applications. The Model 4150 platform has established a track record in street and bracket-racing applications where consistent fuel delivery under varying road conditions is non-negotiable.
