IWG75 Universal Wastegate Actuator (UNF) 150mm 7PSI

Turbosmart Upgraded Wastegate Actuators have been developed to provide maximum possible boost response for your factory frame turbocharger. The Turbosmart IWG75 Series of upgraded Actuators benefit from an increased ‘Working Ratio’ over the factory equipment resulting in improved boost response, throughout the RPM range.
This improved ‘working ratio’ is achieved through an increase to the effective surface area of the diaphragm and revisions to the actual springs fitted resulting in greater leverage of the forces the actuator is working against (boost and backpressure) while still being super-responsive.
Upgrading with the same base pressure as factory, you can expect a broader boost and torque curve through peak boost being achieved earlier in the RPM and being held longer, into higher RPM. These improvements can be amplified with higher base pressures, however tuning and recalibration is likely required.
