High-Flow 50mm External Wastegate Design
The GenV ProGate50 features a large 50mm valve designed to regulate substantial exhaust gas flow.
When the wastegate opens, exhaust gas is diverted around the turbocharger turbine.
This reduces the amount of exhaust energy driving the turbine and helps maintain the desired boost pressure.
The ProGate50's internal geometry is optimized to promote efficient exhaust bypass flow.
This makes it particularly useful in turbocharger applications where smaller wastegates may not provide sufficient bypass capacity.
Actual wastegate requirements depend on engine displacement, exhaust flow, turbocharger characteristics, manifold design, and intended boost pressure.
14 PSI Preinstalled Spring
The TS-0554-1015 comes equipped with a 14 PSI mechanical base spring configuration.
This establishes a nominal mechanical opening pressure of approximately 14 PSI under suitable operating conditions.
Actual boost pressure may vary depending on exhaust backpressure, turbocharger characteristics, wastegate placement, and pressure reference plumbing.
The spring configuration should be selected according to the intended boost pressure and engine management calibration.
Important: An electronic or manual boost controller generally cannot reliably reduce boost pressure below the wastegate's effective mechanical base pressure.
Included Spring Options
The GenV ProGate50 is supplied with a spring kit containing nominal 3 PSI, 5 PSI, 7 PSI, and 14 PSI spring options.
The TS-0554-1015 arrives with the 14 PSI configuration installed.

The Sleeper finish provides the same fundamental boost control functionality as the corresponding standard GenV ProGate50 configuration.
High-Temperature 347 Stainless Steel Body
The GenV ProGate50 incorporates a wastegate body manufactured from high-temperature 347 stainless steel.
External wastegates experience substantial exhaust temperatures and repeated thermal cycling.
The stainless steel construction provides durability in these demanding operating conditions.
The GenV platform also incorporates improved thermal management to help protect the actuator and internal components.
Nitronic 60 Valve Guide
The ProGate50 features a Nitronic 60 valve guide.
Nitronic 60 is a stainless steel alloy known for its resistance to galling and wear.
These characteristics are beneficial in applications involving repeated movement and elevated temperatures.
The valve guide helps maintain proper valve alignment throughout wastegate operation.
316 Stainless Steel Valve Seat
The GenV ProGate50 includes a 316 stainless steel valve seat.
The valve seat provides the sealing interface for the wastegate valve.
Proper seating is important for maintaining consistent boost control and preventing unwanted exhaust bypass when the wastegate is closed.
The valve seat must be installed correctly according to Turbosmart's instructions.
17-7 PH Stainless Steel Springs
The ProGate50 uses 17-7 PH stainless steel springs.
This precipitation-hardening stainless steel provides strength and fatigue resistance.
The springs establish the mechanical closing force acting against the wastegate diaphragm.
Correct spring selection is essential for maintaining the intended mechanical base boost pressure.
CFD-Optimized Exhaust Flow
Turbosmart developed the GenV wastegate platform using computational fluid dynamics and physical flow testing.
The internal geometry is designed to improve exhaust gas bypass efficiency.
Efficient wastegate flow helps maintain stable boost pressure, particularly in applications producing substantial exhaust gas volume.
Proper manifold design and wastegate placement remain critical factors in overall boost control performance.
Modular GenV Actuator
The GenV ProGate50 features a modular actuator assembly.
This design allows compatible actuator components to be serviced or upgraded according to the application.
The locking collar secures the actuator assembly while allowing access to the internal springs using the supplied service tool.
The modular design also supports flexible actuator positioning.
360-Degree Clockable Actuator
The ProGate50 features independently adjustable actuator components.
The actuator housing can be rotated to position the pressure reference ports for improved access and hose routing.
This is especially useful in crowded engine bays where turbocharger components, exhaust manifolds, and intercooler piping compete for limited space.
Proper actuator positioning also helps keep pressure reference hoses away from excessive exhaust heat.
1/8-Inch NPT Pressure Reference Ports
The GenV ProGate50 incorporates 1/8-inch NPT pressure reference ports.
These ports allow the wastegate to be connected to a compatible boost pressure source or boost control system.
Depending on the selected control arrangement, the upper and lower actuator chambers may be connected differently.
Unused ports must be sealed with the appropriate plugs.
Always follow Turbosmart's recommended pressure plumbing diagrams.
V-Band Inlet and Outlet Connections
The ProGate50 uses V-band mounting connections on both the inlet and outlet.
V-band clamps provide secure connections while allowing convenient wastegate removal for servicing.
The included stainless steel weld flanges allow the wastegate to be integrated into compatible custom exhaust manifolds and dump tubes.
Correct flange alignment and proper welding procedures are essential for reliable installation.
Strap-Style V-Band Clamps

These clamps provide secure mechanical connections between the wastegate and its mounting flanges.
The design supports reliable clamping while maintaining a compact installation profile.
Optional Liquid Actuator Cooling
The GenV ProGate50 supports optional liquid actuator cooling.
This feature can help manage actuator temperatures in demanding turbocharger installations.
Liquid cooling may be beneficial when the wastegate is positioned close to high-temperature exhaust components or operates under sustained heavy loads.
The necessary cooling components and plumbing must be installed according to Turbosmart's instructions.
Liquid cooling is optional and is not required for every installation.
Optional Wastegate Position Sensor
The GenV ProGate50 supports an optional wastegate position sensor upgrade.
A position sensor can provide information about wastegate valve movement.
This may be useful for advanced engine management systems, data acquisition, and boost control diagnostics.
The position sensor is sold separately.
Electronic Boost Controller Compatibility
The ProGate50 can be used with compatible electronic boost controllers.
Electronic boost controllers regulate the pressure signal acting on the wastegate diaphragm.
This allows boost pressure to be adjusted above the mechanical base setting within the operating limits of the turbocharger and boost control system.
Proper engine management calibration is essential when increasing boost pressure.
Manual Boost Controller Compatibility
The ProGate50 also supports properly configured manual boost controllers.
Manual boost controllers modify the pressure signal reaching the wastegate actuator.
The mechanical spring pressure remains an important factor in determining the minimum achievable boost pressure.
GenV vs. Gen4 ProGate50
The GenV ProGate50 incorporates several improvements over the earlier Gen4 platform.
These include:
Updated internal flow geometry.

Clockable pressure reference connections.
Optional liquid actuator cooling.
Optional wastegate position monitoring.
Updated V-band mounting components.
The GenV ProGate50 retains the corresponding mounting orientation of the earlier generation, supporting compatible upgrade installations.
However, internal service components should not be assumed interchangeable between generations.
Standard ProGate50 vs. Compressed-Gas ProGate50
Turbosmart offers standard and compressed-gas versions of the GenV ProGate50.
The TS-0554-1015 is the standard pneumatic GenV ProGate50 Sleeper with a 14 PSI spring configuration.
Compressed-gas versions are specifically engineered for applications using regulated CO₂ or compressed air to control wastegate operation.
These versions may incorporate different actuator and diaphragm components.
The standard ProGate50 should not be treated as interchangeable with the compressed-gas version without verifying the appropriate hardware and operating requirements.
Wastegate Placement and Boost Creep
Proper wastegate placement is essential for stable boost control.
The wastegate should be positioned so exhaust gas can flow efficiently from the manifold into the wastegate inlet.
Poor placement or restrictive outlet plumbing can reduce bypass efficiency.
If the wastegate cannot bypass enough exhaust gas, boost pressure may continue increasing even when the valve is fully open.
This condition is commonly referred to as boost creep.
Selecting the correct wastegate size and designing appropriate exhaust plumbing are essential for preventing this problem.
