Stainless Diesel's S300 Spring Gate Actuator. Comes with spring set up for TWIN/Compounds. The sole job of the spring wastegate actuator, is to act as a pressure relief valve that controls the turbocharger boost output. The main parts of an actuator are the spring and adjusting bolt, the spring holds the wastegate shut until the turbo is delivering a predetermined boost level and then opens, allowing the exhaust gas to escape and slow the turbine. This style of actuator is operated by drive pressure. It is more accurate than the old can-style actuators. When setting boost pressures in Twin Turbo Kits, this actuator is 'far & above' the old can-style' actuators. This spring gate works on S300 turbos with T-3 .70 and .80 Wastegated Exhaust Housings.
