Power Now! When turbo exhaust backpressure increases, the stock actuator prematurely blows off the seat, softening boost in the midrange and killing torque. With twice the diaphragm area and spring pressure of the stock wastegate, Banks BigHead Wastegate Actuator keeps the valve seated longer and achieves a higher peak boost, sooner. At peak, BigHead opens the wastegate and holds its position, ... |

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 ... |
