Turbosmart IWG75 Twin Port Universal 150mm Rod 14 PSI Internal Wastegate Actuator TS-0681-6142

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 & 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 & 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 & recalibration is likely required. Twin Port Actuators allow for a wider tuning window by plumbing a reference signal either side of the diaphragm, the boost control strategy can force the pressure into the top cap for a higher ‘high boost’ target and equally, force pressure under the diaphragm, for a lower ‘low boost’ target. Twin Port Control allows for greater boost control options around the base spring pressure. Often a much softer spring than usual can be used, resulting in an overall improvement in dynamics and response.
