850CFM Carburetor Street-Q Series

The Quick Fuel Technology 850CFM Carburetor Street-Q Series is designed for street-driven vehicles and weekend warriors who require reliable fuel delivery without compromising performance. This carburetor is ideal for builders working with naturally aspirated small-block and mid-size engines, making it a popular choice for those upgrading from older carburetors or fine-tuning existing setups.

Engineered with a mechanical secondary design, the Street-Q Series carburetor opens progressively as engine load increases, helping to prevent rich-running conditions and hesitation. Its 850 CFM flow rating is optimal for engines producing between 330 and 400 horsepower, providing sufficient capacity for moderate boost or solid naturally aspirated builds. The precision-machined internals and robust main body construction ensure stable jetting across various RPM ranges.

Street enthusiasts, bracket racers, and classic car restorers will appreciate the Street-Q's balance of street manners and tuning flexibility. Its compact footprint and standard flange mounting allow for seamless integration into existing intake manifold setups, making it a versatile option for a wide range of applications.
