Turbosmart Upgraded Wastegate Actuators have been developed to provide the 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 Turbosmart HP (High Pressure) Actuators Series gives you even more options, with base mechanical spring options up to 40psi. Pre-fitted with 35psi base pressure, these HP actuators will give you the mechanical advantage you need – An Ideal High-Performance Diesel Upgrade.
