Product Description

Turbosmart Upgraded Wastegate Actuators were created to provide the best possible boost response for your OEM frame turbocharger. The Turbosmart IWG75 Series of upgraded Actuators has a greater 'Working Ratio' than factory equipment, resulting in improved boost responsiveness over the RPM range. This improved 'working ratio' is achieved by increasing the effective surface area of the diaphragm and adjusting the actual springs installed, resulting in greater leverage of the forces the actuator is operating against (boost and backpressure) while being extremely responsive. Upgrading with the same base pressure as the factory will result in a broader boost & torque curve due to the peak boost being attained earlier in the RPM range and being held longer into the higher RPM range. These gains can be amplified with larger base pressures, but tuning and recalibration are likely required. By putting a reference signal on either side of the diaphragm, Twin Port Actuators provide a wider tuning window. The boost control approach can force pressure into the top cap for a higher 'high boost' aim and under the diaphragm for a lower 'low boost' target. Twin Port Control provides more boost control options at the base spring pressure. Often a much softer spring than usual can be used, resulting in an overall improvement in dynamics and response.
