Turbosmart IWG75 Universal actuator (UNF) 150mm 0.97 Bar

The Turbosmart wastegate actuators have been developed to ensure the best possible response to the boost pressure for your factory turbocharger. The Turbosmart IWG75 series of upgraded actuators benefit from an increased 'work ratio' over the standard fitment, resulting in improved boost response across the rev range. This improved efficiency is achieved by increasing the effective diaphragm area and reworking the in-built springs, resulting in greater leverage of the forces the actuator counteracts (boost pressure and back pressure) whilst remaining very responsive. If you upgrade with the same base pressure as factory, you can expect a broader boost pressure and torque curve, as peak boost pressure is reached earlier in the rev range and maintained longer, up to higher revs. These benefits can be further enhanced with higher boost pressures, but tuning and re-tuning will most likely be required.
