BigHead® Wastegate Actuator
Product Attributes:
- WARNING CA Proposition 65: Yes
- WARNING CA Proposition 65 Message: California Residents: Prop 65 Warning Warning: Cancer And Reproductive Harm Visit: Www.p65warnings.ca.gov
Features:
- Doubles Stock Diaphragm Area
- Doubles Stock Diaphragm Spring Pressure
- Massive Torque Right From Idle
- Higher Peak Boost Sooner
- More Mid Range Muscle
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, for precise boost control that gives you crisp acceleration and more mid-range pulling power.
