Product Details
The Turbosmart Compressed Gas BoostGate76 (TS-0267-1242) is a high-performance charge air control valve engineered for turbocharged applications requiring precise boost regulation, exceptional airflow capacity, and compatibility with advanced CO₂ boost control systems.
Featuring a 76mm (3.00-inch) zero-offset butterfly valve, 7 PSI preinstalled spring, black finish, and specialized compressed-gas pneumatic actuator, the BoostGate76 offers an innovative alternative to traditional exhaust-side wastegate boost control.
Unlike conventional external wastegates that regulate turbocharger boost by diverting exhaust gas around the turbine, the BoostGate76 operates on the cold side of the turbocharger system. Installed directly into the charge piping, it controls boost pressure by releasing a regulated amount of compressed intake air before that air reaches the engine.
This direct approach to charge air control is particularly beneficial in specialized racing applications where the turbocharger and turbine housing have already been optimized for maximum performance.
The TS-0267-1242 uses a pneumatic diaphragm actuator specifically designed for CO₂ and compressed-air boost control. Its custom Nomex diaphragm is engineered to withstand the elevated pressure differentials associated with fill-and-spill dome pressure control systems.
The BoostGate76 incorporates a large 76mm butterfly-style valve with a zero-offset design, providing precise valve movement and substantial airflow capacity. With a rated flow of 723.7 CFM (20.49 m³/min), the system can bypass significant volumes of compressed intake air.
Its durable construction includes a billet aluminum main body and a 630 stainless steel butterfly valve and shaft. The V-band mounting arrangement offers 360-degree positioning flexibility, while the actuator can be clocked into three positions spaced 120 degrees apart.
Designed for serious motorsport applications, the BoostGate76 is particularly well suited for drag racing vehicles using sophisticated boost-by-time, boost-by-gear, or dome pressure control strategies.
Whether developing a high-horsepower Honda K20/K24 turbocharger system, building a competition B-Series engine, or configuring a dedicated drag racing vehicle, the Turbosmart BoostGate76 TS-0267-1242 provides an advanced solution for direct charge air boost management.

Direct Charge Air Boost Control
The BoostGate76 differs fundamentally from a traditional external wastegate.
A conventional external wastegate controls boost by redirecting exhaust gas around the turbocharger turbine.
The BoostGate76 instead regulates the compressed intake air produced by the turbocharger.
When the valve opens, compressed air is released from the charge piping, reducing the amount of boost pressure delivered to the engine.
This provides a direct method of controlling intake manifold boost pressure.
Because the BoostGate76 operates independently of the turbine exhaust bypass path, it can be useful in applications where the turbocharger and turbine housing have been optimized for maximum performance.
76mm Zero-Offset Butterfly Valve
The BoostGate76 features a large 76mm butterfly valve.
Its zero-offset design allows controlled valve movement and precise regulation of compressed-air bypass flow.
The butterfly configuration provides substantial airflow capacity while maintaining a compact installation footprint.
This design is especially useful in motorsport applications requiring rapid and repeatable changes in charge air bypass flow.
723.7 CFM Flow Capacity
The TS-0267-1242 features a rated flow capacity of 723.7 CFM, equivalent to approximately 20.49 cubic meters per minute.
This substantial airflow capacity allows the BoostGate76 to bypass significant amounts of compressed intake air.
Correct valve sizing remains dependent on the turbocharger's airflow output, charge piping arrangement, and intended boost control strategy.
Compressed-Gas Pneumatic Actuator
The BoostGate76 uses a pneumatic actuator designed specifically for compressed-gas boost control.
Unlike the fully electronic BoostGate, this version relies on pressure applied to the actuator diaphragm.
A compatible CO₂ boost control system regulates actuator dome pressure to influence valve movement.
This arrangement provides an alternative to electronic motor-driven charge air control.
Custom Nomex Diaphragm
The TS-0267-1242 incorporates a specialized Nomex diaphragm designed for compressed-gas applications.
The diaphragm is engineered to accommodate the elevated pressure differentials associated with CO₂ boost control.
Its construction supports fill-and-spill boost control systems that regulate actuator dome pressure.
7 PSI Preinstalled Spring
The BoostGate76 comes equipped with a nominal 7 PSI actuator spring configuration.
The spring establishes the mechanical actuator pressure setting before additional dome pressure control is applied.
Compatible alternative spring configurations allow the actuator to be adjusted for different boost control requirements.
Important: The 7 PSI spring rating does not represent the maximum boost pressure capability of the turbocharger system. Actual boost regulation depends on the valve, actuator configuration, charge air flow, and controller calibration.
External CO₂ Fill-and-Spill Control
The TS-0267-1242 is designed for use with external compressed-gas control hardware.
A typical setup uses a regulated CO₂ supply, fill solenoid, spill solenoid, dome pressure sensor, and compatible boost controller.
The fill solenoid increases dome pressure, while the spill solenoid releases pressure.
By regulating dome pressure, the controller can influence BoostGate valve movement and manage charge air bypass.
Important: The TS-0267-1242 does not feature integrated control solenoids. The integrated-solenoid version is sold separately under part number TS-0267-1252.
Billet Aluminum Main Body
The BoostGate76 incorporates a billet aluminum main body.
This construction provides strength while keeping weight relatively low.
The aluminum housing is designed for installation in the compressed intake air system rather than the high-temperature exhaust stream.
630 Stainless Steel Butterfly and Shaft
The valve and shaft are manufactured from 630 stainless steel.
These components provide durability for repeated valve operation.
The stainless steel construction supports consistent movement and long-term performance in demanding charge air control applications.
360-Degree V-Band Mounting Flexibility
The BoostGate76 features V-band mounting connections that allow flexible positioning during installation.
The valve body can be oriented to accommodate different charge piping layouts and engine bay configurations.
This is especially beneficial in custom motorsport installations where packaging space may be limited.
Three-Position Clockable Actuator
The pneumatic actuator can be positioned in three different orientations spaced 120 degrees apart.
This allows the installer to improve access to pressure connections and provide additional clearance around surrounding components.
Proper actuator positioning also helps simplify compressed-gas hose routing.
Compatible ProPort-Style Mounting Flanges
The BoostGate76 utilizes mounting flanges compatible with the corresponding Turbosmart ProPort flange arrangement.
This can simplify installation in applications already equipped with appropriate ProPort-style charge piping connections.
All flange dimensions and mounting interfaces should be verified before installation.
Optional Valve Position Monitoring
The BoostGate platform supports an optional position sensor arrangement.
This allows compatible engine management or data acquisition systems to monitor valve movement.
Position feedback may be useful for advanced boost control calibration and diagnostics.
The position sensor is sold separately.
