Turbosmart pSG50CG StraightGate50 50mm Compressed Gas External Wastegate with Integrated Solenoids – 7 PSI – TS-0565-1252

Product Description

Upgrade your turbocharger boost control system with the Turbosmart TS-0565-1252 pSG50CG Compressed Gas StraightGate50 External Wastegate, a high-performance wastegate designed for demanding turbocharged engine and motorsport applications. Featuring a 50mm zero-offset butterfly valve, integrated boost-control solenoids and a dome-pressure sensor, this advanced wastegate combines high-flow exhaust bypass capability with a streamlined compressed-gas boost-control solution.

Designed for use with compatible CO₂ and compressed-air boost-control systems, the Turbosmart StraightGate50 incorporates key control components directly into the wastegate cap. This integrated design helps reduce external plumbing complexity while providing a purpose-built arrangement for managing dome pressure and wastegate operation.

With its 7 PSI base spring configuration and specialised diaphragm design, the pSG50CG is an ideal option for performance enthusiasts, engine builders and motorsport specialists seeking a high-flow external wastegate for a compatible turbocharger system.

Whether you are building a competition engine, upgrading a high-performance turbocharger setup or developing a custom forced-induction system, the Turbosmart StraightGate50 provides a specialised solution for advanced boost control.

Integrated Compressed-Gas Boost Control

One of the key features of the Turbosmart pSG50CG is its integrated control system. The wastegate cap incorporates the fill and spill solenoids and dome-pressure sensor required for compatible compressed-gas boost-control strategies.

By integrating these components into the wastegate assembly, Turbosmart reduces the need for separately mounted control solenoids and a remote dome-pressure sensor. This can simplify installation, reduce external plumbing requirements and create a more organised engine bay.

The integrated control arrangement is designed for compatible CO₂ and compressed-air systems that use dome pressure to influence wastegate operation. Correct controller configuration, pressure regulation and plumbing remain essential for reliable performance.

High-Flow 50mm StraightGate Design

The Turbosmart StraightGate50 features a 50mm zero-offset butterfly-style valve engineered to provide substantial exhaust bypass capacity. Unlike traditional poppet-style wastegates, the StraightGate uses a centrally pivoting butterfly valve to regulate exhaust flow through the wastegate.

The zero-offset design allows exhaust drive pressure to act across both sides of the valve, helping balance the forces acting on the valve and supporting controlled operation across its working range.

This design is intended to provide a more linear relationship between valve position and exhaust flow, making it suitable for demanding turbocharger systems where precise boost regulation and high exhaust-flow capacity are important.

Wastegate sizing should always be matched to the engine's exhaust flow, turbocharger characteristics, exhaust manifold design and intended operating range.

7 PSI Base Spring Configuration

The TS-0565-1252 features a 7 PSI base spring configuration, providing a defined starting point for selecting the wastegate to suit your turbocharger and boost-control requirements.

Base spring pressure influences the wastegate's opening behaviour, while the final boost level depends on the pressure applied to the dome, control strategy, exhaust backpressure and the complete engine configuration.

The 7 PSI specification does not represent the maximum boost pressure achievable by the system. Any increase in boost must remain within the safe operating limits of the engine, turbocharger, fuel system and supporting components.

Professional installation and tuning are recommended to establish the appropriate boost-control settings for your application.

Designed for CO₂ and Compressed-Air Systems

The pSG50CG is specifically designed for compressed-gas boost-control applications using a suitable external pressure source, including CO₂ or compressed air.

Its specialised diaphragm is engineered to accommodate the pressure differentials associated with compressed-gas control strategies. Combined with the integrated solenoids and dome-pressure sensor, this configuration provides a dedicated solution for compatible fill-and-spill boost-control arrangements.

The integrated components help simplify system packaging, but the compressed-gas supply, fittings, electrical connections and controller must still be configured correctly for the intended application.

Durable Construction for Performance Applications

Turbocharger wastegates operate in demanding environments exposed to high exhaust temperatures, vibration and repeated mechanical movement. The Turbosmart StraightGate50 uses performance-oriented materials designed for these conditions.

Construction features include a stainless steel wastegate body, a stainless steel butterfly valve and shaft, heat-treated stainless steel V-band clamps, an aluminium actuator assembly and stainless steel linkage components.

The specialised diaphragm and actuator arrangement are designed to support reliable operation in compressed-gas boost-control systems when correctly installed and maintained.

These materials and construction features make the pSG50CG suitable for appropriately configured high-performance turbocharger applications.

Simplified Installation with Integrated Solenoids

The integrated Control In Cap arrangement is designed to reduce the number of separately mounted boost-control components required for a compatible compressed-gas installation.

By housing the fill and spill solenoids and dome-pressure sensor within the wastegate cap, the system can help reduce external plumbing complexity and provide a more compact installation.

A correctly configured compressed-gas system still requires suitable pressure lines, fittings, electrical connections and controller settings. All components must be selected to operate safely within the intended pressure range.

Ideal for Motorsport and High-Performance Builds

The Turbosmart pSG50CG StraightGate50 is suited to performance applications where high exhaust-flow capacity and advanced compressed-gas boost control are priorities.

It is a practical consideration for professional engine builders, turbocharger specialists and motorsport enthusiasts developing custom turbocharged systems. Whether you are assembling a competition engine, upgrading a high-output turbocharger setup or refining a dedicated track vehicle, the StraightGate50 provides a specialised external wastegate solution.

Its 50mm valve configuration makes it important to consider exhaust flow, turbocharger sizing and engine requirements before installation.

Installation and Compatibility

The Turbosmart TS-0565-1252 is designed for turbocharger systems that do not have an internal wastegate. Depending on your turbocharger and exhaust manifold configuration, installation may require fabrication or modification to provide suitable mounting and exhaust plumbing.

Use high-quality pressure fittings and ensure that all connections are properly sealed. Provide adequate cool airflow around the upper diaphragm housing and keep the wastegate away from excessive heat. Follow the manufacturer's installation requirements and avoid wrapping the wastegate body in exhaust wrap.

The integrated solenoids and dome-pressure sensor must be connected and configured according to the manufacturer's instructions. Professional installation and boost calibration are strongly recommended.

Always verify that boost pressure remains within the safe operating limits of the engine, turbocharger, fuel system and other supporting components. Incorrect installation or boost settings can result in engine damage or personal injury.
