Quick Fuel Technology’s new Street-Q carburetor is intended to deliver legendary Q-Series performance to hardcore street enthusiasts at a reduced price. The major differences between the Street-Q and the race-bred Q-Series is the substitution of cast metering blocks and a cast throttle body in place of fully-machined billet components. All of the critical functionality is retained – 2-circuit metering, downleg boosters, changeable idle and high-speed air bleeds and 4-corner idle. A universal throttle lever design accommodates Ford A/T kickdowns, 700-R4 bracket mounting holes and the ability to mount brackets for Chrysler vehicles. Available sizes include 650, 750, 850, and 950cfm for mechanical secondary models and a 750 vacuum secondary is also offered.

  • Lightweight die-cast aluminum components

  • 2-circuit metering – 4-Corner idle system
