Description
Under high-boost conditions, the stock actuator’s weak spring allows the wastegate to blow open, limiting midrange torque. Bleed orifices (also known as “boost foolers”) just make it worse. Only Banks solves this problem by replacing the boost actuator. BigHead holds the wastegate closed for quicker boost, then controls the opening to maintain peak boost for superior acceleration and mid-range pulling power.
Key Features
- Quick, Controlled Boost
- Produces massive torque right from idle
- Doubles stock’s diaphragm area & spring pressure
- Keeps valve seated longer achieving higher peak boost, sooner
- Crisp acceleration and more mid-range pulling power
