680 CFM - Vacuum Secondaries - Black - Gasoline - Electric Choke

Splitting the difference between 650 and 700-ish airflow, the 680 CFM Brawler Street is a sweet spot for responsive street cars that need a little more headroom. Vacuum secondaries smooth the transition into the back barrels, keeping drivability civilized while still delivering a noticeable top-end bump. Black billet metering blocks and throttle body provide durability, the electric choke simplifies start-ups, and the calibration is set up for today’s fuels with easy adjustability baked in.
