Banks exclusive BigHead wastegate actuator prevents wastegate blow-open by keeping the valve seated at higher pressures, increasing mid-range torque and top-end power.
- For higher peak boost, sooner
- 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.
