Turbosmart pSG76CG StraightGate76 76mm Compressed Gas External Wastegate – 7 PSI

Product Description

Take your turbocharger boost-control system to the next level with the Turbosmart TS-0567-1242 pSG76CG Compressed Gas StraightGate76 External Wastegate. Designed for high-performance turbocharged engines and demanding motorsport applications, this 76mm external wastegate combines high-flow exhaust bypass capacity with specialised diaphragm actuation for compressed-gas boost-control systems.

Engineered for use with compatible CO₂ and compressed-air boost controllers, the Turbosmart StraightGate76 provides a dedicated solution for applications requiring external wastegate control. Its 7 PSI base spring configuration offers a defined starting point for boost-control setup, while the zero-offset butterfly valve design is engineered to deliver substantial exhaust flow and controlled wastegate operation.

Whether you are building a high-output turbocharged engine, upgrading a competition vehicle or developing a custom forced-induction system, the Turbosmart pSG76CG provides a purpose-designed external wastegate for advanced performance applications.

High-Flow 76mm Wastegate Design

The Turbosmart StraightGate76 features a 76mm butterfly-style valve designed to provide high exhaust bypass capacity. An external wastegate regulates turbocharger operation by diverting exhaust gases around the turbine, helping control turbine speed and manage boost pressure.

The StraightGate's zero-offset inline butterfly design is engineered to support substantial flow with a progressive relationship between valve movement and flow characteristics. This makes it suitable for demanding turbocharger systems where effective exhaust bypass and precise boost management are important.

The published flow specification is approximately 723.7 CFM, or 20.49 cubic metres per minute. Actual flow performance depends on operating pressure, temperature, installation configuration and exhaust-system conditions.

Designed for CO₂ and Compressed-Air Boost Control

The pSG76CG is purpose-built for compressed-gas boost-control systems that use an external pressure source, such as CO₂ or compressed air, to influence wastegate opening.

Its specialised diaphragm design is engineered to handle the higher pressure differentials associated with compressed-gas control strategies, including fill-and-spill arrangements. This makes the wastegate suitable for advanced boost-control systems commonly used in high-performance and motorsport applications.

Unlike the integrated-solenoid variant, this model is designed to work with a compatible external boost-control arrangement. Appropriate solenoids, pressure sensing, plumbing and control hardware must be selected separately as required by the intended system.

7 PSI Base Spring Configuration

The Turbosmart TS-0567-1242 features a 7 PSI base spring configuration, providing a defined baseline for selecting and configuring the wastegate for your turbocharger system.

The base spring influences the wastegate's opening behaviour, while the final boost level depends on the complete boost-control system, pressure applied to the actuator, turbocharger characteristics and engine calibration.

The 7 PSI specification should not be interpreted as the maximum boost pressure the system can achieve. Any increase in boost must remain within the safe operating limits of the engine, turbocharger, fuel system and supporting components.

Durable Materials for Demanding Applications

The StraightGate76 incorporates performance-oriented materials selected for the thermal and mechanical demands of turbocharger exhaust systems.

Key construction features include a stainless steel butterfly valve and shaft, a stainless steel main body, heat-treated stainless steel V-Band clamps, and an aluminium bracket and actuator assembly. The diaphragm is designed specifically for the pressure demands of compressed-gas boost control.

These materials support durability in demanding operating environments, where exhaust heat, vibration and repeated valve movement place significant loads on the wastegate assembly.

External Wastegate Configuration

The Turbosmart pSG76CG is designed for turbocharger systems that do not use an internal wastegate. It provides an external exhaust bypass arrangement that can be integrated into a compatible exhaust manifold or turbine-side exhaust system.

Depending on your engine and turbocharger configuration, installation may require custom manifold fabrication, suitable mounting provisions and correctly sized exhaust plumbing. Correct placement and installation are essential for reliable operation and effective boost control.

Ideal for High-Performance and Motorsport Builds

The Turbosmart StraightGate76 is suited to performance engine builders, turbocharger specialists and motorsport enthusiasts developing high-flow turbocharger systems.

Whether you are assembling a competition engine, upgrading a custom turbocharged vehicle or configuring a compressed-gas boost-control system, the pSG76CG offers a dedicated external wastegate solution designed around high exhaust flow and specialised actuator operation.

Its large valve size makes correct wastegate sizing particularly important. Consider engine displacement, turbine characteristics, exhaust manifold design and expected power level when determining whether a 76mm wastegate is appropriate for your application.

Installation and Compatibility

The Turbosmart pSG76CG is intended for turbocharger systems without an internal wastegate. Correct installation requires a suitable external wastegate mounting arrangement, appropriate exhaust plumbing and compatible compressed-gas control hardware.

Use high-quality fittings to help maintain reliable sealing throughout the pressure-control system. Allow adequate cool airflow around the upper diaphragm housing, and maintain the clearances specified by the manufacturer. Do not wrap the wastegate body in exhaust wrap.

Installation and boost-control setup should be carried out by a suitably qualified technician. Incorrect installation or excessive boost pressure can cause engine damage or personal injury. Always ensure that boost settings remain within the safe limits of your engine and supporting components.
