Turbosmart GenV WG45 HyperGate45 Compatibility
The TS-0550-3151 is designed for the Turbosmart GenV WG45 HyperGate45 external wastegate.
The HyperGate45 features a 45mm valve and is designed for turbocharged applications requiring effective exhaust gas bypass control.
The replacement spring kit is compatible with the wastegate's internal spring chamber and is intended to maintain the mechanical spring operation of the assembly.
Using genuine Turbosmart springs helps ensure that replacement components are appropriate for the wastegate's internal design.
Turbosmart GenV WG50 ProGate50 Compatibility
The TS-0550-3151 also fits the Turbosmart GenV WG50 ProGate50 external wastegate.
The ProGate50 features a larger 50mm valve, making it suitable for many demanding turbocharger applications.
Although the HyperGate45 and ProGate50 use different valve sizes, they share the compatible spring kit specified by Turbosmart.
This allows the same replacement spring kit to service either wastegate model.
Understanding Wastegate Spring Pressure
An external wastegate regulates turbocharger boost pressure by controlling the amount of exhaust gas bypassing the turbine wheel.
The internal wastegate spring provides resistance against the pressure acting on the wastegate diaphragm.
As pressure increases, the force acting on the diaphragm begins to overcome the spring resistance.
This allows the wastegate valve to open and divert exhaust gas away from the turbocharger turbine.
The spring configuration establishes the nominal mechanical base boost pressure.
Actual boost pressure can vary depending on exhaust backpressure, turbocharger sizing, wastegate placement, boost controller settings, and engine operating conditions.
GenV WG45/WG50 Spring Pressure Options
Turbosmart offers several individual spring options for the GenV WG45 and WG50 wastegates.
These include:
3 PSI Inner Spring – Orange: Turbosmart TS-0550-3085.
5 PSI Inner Spring – Yellow: Turbosmart TS-0550-3086.
7 PSI Middle Spring – Green: Turbosmart TS-0550-3087.
14 PSI Outer Spring – Blue: Turbosmart TS-0550-3088.
These individual spring options can be used to establish different mechanical boost pressure configurations according to Turbosmart's approved spring selection guidelines.
Important: These are manufacturer-listed individual spring options for the compatible wastegates. They should not be interpreted as a confirmed itemized contents list for TS-0550-3151.
Wastegate Spring Replacement
The Turbosmart TS-0550-3151 provides genuine replacement spring components for servicing a compatible GenV WG45 or WG50.
Spring replacement may be necessary when existing components are damaged, corroded, incorrectly configured, or unsuitable for a revised boost control strategy.
A spring replacement can also be performed during a broader wastegate inspection or rebuild.
During servicing, inspect the diaphragm, valve, guide, spring seats, and other internal components for wear or damage.
Base Boost Pressure Configuration
Wastegate spring selection is an important part of turbocharger boost management.
A lower spring pressure generally establishes a lower mechanical base boost setting.
A higher spring pressure provides greater resistance against wastegate opening.
Turbosmart wastegates can support approved spring combinations to achieve different base pressure configurations.
However, spring selection must follow the manufacturer's specifications.
Do not assume that every spring in the kit should be installed simultaneously.
The correct arrangement depends on the desired mechanical base pressure and the wastegate's approved spring combinations.
Electronic Boost Control Compatibility
The GenV WG45 HyperGate45 and WG50 ProGate50 can be used with compatible electronic boost controllers.
Electronic boost controllers regulate pressure acting on the wastegate diaphragm to influence boost pressure.
The wastegate spring establishes the mechanical foundation for this control strategy.
Changing the spring configuration can affect the available boost control range and overall boost response.
The TS-0550-3151 allows the mechanical spring configuration to be serviced or adjusted as necessary.
Manual Boost Control Applications
The replacement spring kit can also be used in wastegate systems utilizing compatible manual boost controllers.
A manual boost controller modifies the pressure signal reaching the wastegate.
The selected wastegate spring must still be appropriate for the desired operating conditions.
An excessively stiff spring may prevent the system from achieving a sufficiently low boost pressure.
High-Horsepower Turbocharger Applications
The HyperGate45 and ProGate50 are commonly used in performance turbocharger installations.
High-output engines can generate substantial exhaust flow and backpressure.
Correct wastegate sizing, placement, and spring selection are important for maintaining stable boost pressure.
The TS-0550-3151 provides genuine replacement springs for maintaining the mechanical boost control system.
It does not increase the wastegate's valve diameter or exhaust bypass capacity.
Genuine Turbosmart Replacement Components
Turbosmart develops its replacement springs using the same engineering standards applied to its complete wastegate assemblies.
The springs are designed and developed in-house and hand-tested to meet manufacturer specifications.
Using genuine replacement components helps maintain compatibility with the wastegate's internal spring chamber and operating mechanism.
This is particularly important in high-performance applications where consistent boost control is essential.

Boost Pressure and Engine Tuning
Changing wastegate spring pressure can affect turbocharger response, boost pressure, and engine operating conditions.
Even when using the same electronic boost controller settings, a different spring configuration may change the system's behavior.
After replacing or reconfiguring wastegate springs, verify the mechanical base pressure and review the engine management calibration.
Professional tuning is recommended for high-output turbocharged applications.
