The Compressed Gas StraightGate76 (solenoid) is the first ever boost control integrated CO2 operated external wastegate. Turbosmart has taken the complexity of out of CO2 boost control by taking the ÒspillÓ and ÒfillÓ control solenoids as well as the dome pressure sensor required for CO2 boost control and integrating them directly into the wastegate cap. Combine this integrated control cap with TurbosmartÕs range of award winning StraightGate bodies and you have the worldÕs highest-flowing, user friendly external CO2 wastegates period! TurbosmartÕs StraightGate wastegate design comprises a zero-offset inline butterfly-style valve that allows enormous flow and almost linear control across the operating range. This leads to unparalleled boost control for your high performance applications. Compressed Gas variants of the StraightGate are designed specifically for wastegate control strategies that use an external pressure source such as CO2 or compressed air to vary the wastegate opening position. Longevity and performance are ensured by an inverted high pressure Nomex diaphragm built specifically for the higher pressure differentials found in CO2 / Compressed Air boost control strategies. Integrating the electronic control components into the cap is the icing on the cake, simplifying the plumbing to a single regulated pressure line from the CO2 or Compressed Air source straight to the wastegate cap. This eliminates up to 8 pressure fittings and possible failure points from the critical boost control system. TurbosmartÕs proprietary control in cap technology is designed to reduce system error and maximize response, the Compressed Gas StraightGate is Engineered to Win!
