Power Now! Keep your wastegate from blowing open — when turbo exhaust backpressure increases, the stock actuator prematurely blows off its seat, softening boost in the midrange and killing torque. With a diaphragm twice the size of the stock wastegate & double the spring pressure of the stock, the Banks Big Head wastegate actuator for 1999.5(Late)-2003 Ford F250/F350 7.3 Powerstroke models with Stock Turbo or Banks Turbo is a simple way to achieve higher peak boost and increase mid-range pulling power.
- Doubles the stock’s diaphragm area & spring pressure
- Produces massive torque right from idle
- Achieves higher peak boost sooner
- More mid-range muscle
- Backed by a 2-year warranty
Note: Designed to work with the stock turbo or Banks turbo.
Banks Big Head produces massive torque right from idle, achieves a higher peak boost — sooner — and maintains more boost throughout the powerband by eliminating premature wastegate blow-open. With higher overall peak boost levels, quicker spool-up and increased torque. The Banks Big Head is the perfect addition to any performance module, air intake or exhaust system.
