The ball-and-spring portion was designed with a lightweight polymer ball that quickly leaves its seat to eliminate detrimental boost spikes normally associated with poorly designed boost controllers. The polymer ball will also re-seat itself quicker between shifts to allow for superior transient boost response. The BBC also uses a built in bleed system to regulate the desired boost curve that is adjustable by air bleed jets included in the kit. The heart of the Billet Boost Controller’s design is its click-adjustable knob. An integrated detent allows the user precise adjustment when increasing or decreasing boost. Simply turn the knob and count the number of clicks it takes to get you where you want to be.

The BBC comes with boost/vacuum line, a mounting bracket, three air bleeds, wire ties.
