Description:
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.

Banks is one of the premier names in turbocharged diesel modification, but there is a lot more to the company than just that. Banks engines have been used everyone from NAVY Seals to winners at the Bonneville salt-flats.
Banks' name precedes him and it is no coincidence that he teaches to graduate students of the General Motors Institute. Banks' engineering spirit has allowed him to innovate great things, such as the twin-turbo small block Chevy in the late 1970's.

Q: What is a wastegate? Why buy a wastegate?
A: A wastegate regulates boost by allowing excess exhaust pressure to bleed off. Wastegates generally come in two different types. The first is an internal wastegate, which is controlled by a wastegate actuator and bleeds directly into the exhaust system. An external wastegate is controlled by a boost controller and can be directed to bleed either into the exhaust system or directly into the atmosphere. It's mounted wherever there's space for it. External wastegates can handle more boost, but can be too big to fit in the space next to the turbo.
Q: How do you install a wastegate?
A: Wategates are mounted onto the turbo manifold by using a flange. Basic bolting of it is needed for installation.
