A proven bracket and heads-up favorite, the 750 CFM Brawler Race adds airflow for stronger mid- and high-rpm charge while maintaining crisp throttle behavior. Mechanical secondaries give direct control; replaceable bleeds and four-corner idle enable surgical mixture management. With stable throttle-shaft geometry and modern fuel curves, it delivers repeatable performance pass after pass—exactly what you want when consistency wins rounds.

Features:

  • The latest technology in air/fuel calibrations for street or race engine demands
  • Available in both vacuum and mechanical secondary versions to meet your needs
  • All models have dual inlet fuel bowls with sight glass windows for safe and easy float adjustments
  • Changeable idle and high speed air bleeds for easy tuning along with four-corner idle adjustment on mechanical secondary models
  • Performance models include billet metering blocks and throttle bodies with precision throttle shafts to ensure long term performance
  • Now available in a black coated finish for corrosion protection and good looks
