Integrated Control-in-Cap Technology
The defining feature of the TS-0553-1252 is Turbosmart's integrated control-in-cap design.
Traditional CO₂ wastegate control systems typically require separate fill and spill solenoids, external pressure fittings, additional hoses, and a dome pressure sensor.
The HyperGate45 CG incorporates the fill solenoid, spill solenoid, and dome pressure sensor directly into the wastegate cap.
This reduces external plumbing complexity and simplifies integration with compatible engine management systems.
The integrated design also provides a compact solution for engine bays where space is limited.
Integrated CO₂ Fill Solenoid
The fill solenoid controls the supply of regulated compressed gas to the upper wastegate actuator chamber.
Increasing dome pressure applies additional closing force to the wastegate diaphragm.
This allows a compatible boost control system to influence wastegate opening behavior and regulate boost pressure above the mechanical spring setting.
The solenoid is controlled electronically through a compatible ECU or boost controller.
Integrated CO₂ Spill Solenoid
The spill solenoid controls the release of compressed gas from the upper actuator chamber.
By venting dome pressure, the boost control system can reduce the additional closing force acting on the wastegate.
The fill and spill solenoids work together to regulate dome pressure according to the commanded boost control strategy.
This provides more advanced control than a conventional spring-only wastegate arrangement.
Built-In Dome Pressure Sensor
The TS-0553-1252 includes an integrated dome pressure sensor.
The sensor provides pressure feedback to a compatible boost control system.
Dome pressure feedback is particularly useful for closed-loop compressed-gas boost control strategies.
By monitoring actual dome pressure, the controller can adjust solenoid operation to maintain the desired pressure target.
7 PSI Mechanical Base Boost Pressure
The HyperGate45 CG comes equipped with a nominal 7 PSI spring configuration.
This establishes the wastegate's mechanical base pressure under appropriate operating conditions.
The integrated compressed-gas control system allows additional pressure to be applied to the actuator dome to influence wastegate operation.
Actual boost pressure depends on spring selection, exhaust backpressure, turbocharger characteristics, and control system calibration.
Important: The 7 PSI rating describes the installed mechanical spring configuration, not the maximum boost pressure the wastegate can control.
Inverted Diaphragm for Compressed-Gas Control
The HyperGate45 CG incorporates a specialized inverted diaphragm.
This design is intended for compressed-gas applications where the actuator may experience substantial pressure differences between its upper and lower chambers.
The diaphragm configuration supports the use of regulated CO₂ or compressed air for advanced wastegate control.
45mm High-Flow Wastegate Design
The HyperGate45 features a 45mm wastegate valve designed to regulate exhaust gas flow around the turbocharger turbine.
When the wastegate opens, exhaust gas is redirected away from the turbine, helping control turbine speed and boost pressure.
The 45mm valve provides substantial bypass capacity for compatible turbocharger systems.
Correct wastegate sizing depends on engine displacement, turbocharger characteristics, exhaust manifold design, and intended boost pressure.
High-Temperature 347 Stainless Steel Body
The GenV HyperGate45 CG features a wastegate body manufactured from 347 stainless steel.
This material is well suited for high-temperature exhaust environments and repeated thermal cycling.
Its durability makes it appropriate for demanding turbocharger installations.
Nitronic 60 Valve Guide
The HyperGate45 CG incorporates a Nitronic 60 valve guide.
Nitronic 60 is known for its resistance to wear and galling, making it suitable for components exposed to repeated movement and elevated temperatures.
The valve guide helps maintain proper wastegate valve alignment and consistent operation.
316 Stainless Steel Valve Seat
The GenV HyperGate45 CG includes a 316 stainless steel valve seat.
The valve seat provides a durable sealing interface for the wastegate valve.
Proper sealing helps prevent unwanted exhaust bypass when the wastegate is closed.
17-7 PH Stainless Steel Springs
The HyperGate45 CG utilizes 17-7 PH stainless steel actuator springs.
These springs provide the mechanical closing force required to establish the selected base boost pressure.
The material offers strength and fatigue resistance for demanding performance applications.
CFD-Optimized Exhaust Flow
Turbosmart developed the GenV wastegate platform using computational fluid dynamics and physical flow testing.
The optimized internal geometry promotes efficient exhaust bypass flow.
Effective exhaust bypass is essential for stable boost regulation, particularly in high-horsepower applications producing substantial exhaust gas volume.
Modular GenV Actuator
The HyperGate45 CG incorporates Turbosmart's modular GenV actuator construction.
This design allows compatible spring configurations to be changed and serviced without replacing the complete wastegate.
The locking collar secures the actuator assembly while providing access to the internal spring system using the supplied service tool.
360-Degree Clockable Actuator Housing
The GenV HyperGate45 CG features a clockable actuator housing.
The actuator can be rotated to improve access to pressure connections and simplify installation.
This is particularly beneficial in custom turbocharger installations with limited engine bay clearance.
Optional Liquid Actuator Cooling
The GenV HyperGate45 CG supports optional liquid actuator cooling.
This feature can help manage actuator temperatures in installations exposed to extreme exhaust heat.
Liquid cooling may be beneficial in applications involving sustained high engine loads or limited airflow around the wastegate.
Cooling components and plumbing must be installed according to Turbosmart's recommendations.
Optional Wastegate Position Sensor
The GenV HyperGate45 platform supports an optional wastegate position sensor.
This feature allows compatible engine management systems to monitor wastegate valve movement.
Position monitoring may be useful for advanced tuning, diagnostics, and motorsport applications.
The optional position sensor is not included with TS-0553-1252.
V-Band Mounting Connections
The HyperGate45 CG uses V-band inlet and outlet connections.
V-band clamps provide secure mounting while allowing convenient removal for servicing.
The included weld flanges allow integration with custom turbocharger manifolds and exhaust dump tubes.
