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. _x000D_ 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. _x000D_ 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. _x000D_ _x000D_ Available In _x000D_ _x000D_ Twin Port Universal (UNF) 14psi / 1.0 BAR:TS-0681-6142 _x000D_ Single Port Universal (UNF) 14psi / 1.0 BAR:TS-0681-5142 _x000D_ Single Port Universal (UNF) 10psi / 0.7 BAR:TS-0681-5102 _x000D_ Single Port Universal (UNF) 7psi / 0.5 BAR:TS-0681-5072 _x000D_ Single Port Universal (M6) 10psi / 0.7 BAR:TS-0681-4102 _x000D_ _x000D_ Features _x000D_ _x000D_ Proprietary Silicon Nomex Diaphragm _x000D_ Choice of Springs from 3psi to 26psi (Optional) _x000D_ High Grade Billet Aluminum Construction _x000D_ Stainless Steel Rods and Clevis _x000D_ Turbosmart Unique Locking Collar System _x000D_ _x000D_ This is a Universal Single Port IWG75 Actuator supplied with a 150mm long, 1/4" UNF threaded rod for fitment on a wide variety of turbochargers.
