Turbosmart Hypergate 45mm Wastegate 14psi Black
Serious Boost Control Starts With the Right Wastegate
When you're pushing a turbocharged combination hard, boost control isn't something you want to compromise on.
The Turbosmart GenV WG45 HyperGate45 is a motorsport-proven 45mm external wastegate engineered for high-flow performance, precise boost control, extreme temperature resistance, and long-term reliability.
Whether you're building a street car, drag car, roll-racing setup, or dedicated competition vehicle, the HyperGate45 gives you the control needed to keep boost where you command it.
Why Choose the GenV HyperGate45?
Turbosmart didn't simply update the previous HyperGate—they redesigned the GenV range from the ground up.
Using CFD optimization and extensive in-house validation, the GenV HyperGate45 was engineered to deliver excellent exhaust flow while improving thermal management, durability, and installation flexibility.
The result is a compact 45mm wastegate capable of supporting demanding turbo applications without sacrificing boost-control accuracy.
Built for Heat. Built for Boost. Built to Last.
The HyperGate45 combines high-temperature materials with a carefully engineered valve and actuator design to withstand the extreme environment of a turbocharged exhaust system.
Key features include:
- 45mm external wastegate design
- High-flow CFD-optimized construction
- Bench-validated flow performance
- Excellent thermal performance
- High fatigue resistance for demanding applications
- Nitronic 60 valve guide
- High-temperature 347 stainless-steel body
- 17-7 PH stainless-steel springs
- Rotatable / clockable actuator housing
- Variable actuator cap and base
- 360-degree reference hose routing options
- 1/8" NPT reference ports
- Strap-style V-band clamps
- Optional liquid actuator cooling
- Optional wastegate position sensor available separately
Easy Installation & Configuration
The GenV HyperGate45 uses Turbosmart's collar-locking system, allowing the actuator housing to be rotated to suit your engine bay.
That means you're not stuck fighting inconvenient boost-reference port locations when space around your turbo, manifold, downpipe, or intercooler piping is limited.
The GenV WG45 is also designed as a direct-fit upgrade for compatible Gen4 Turbosmart wastegate applications, making it an excellent option when upgrading an existing setup.
Multiple Boost Spring Options Included
Your turbo setup shouldn't be limited by the spring installed in the wastegate.
The HyperGate45 includes multiple springs so you can configure the mechanical wastegate pressure to better match your combination and boost-control strategy.
Included spring pressures:
- 3 PSI
- 5 PSI
- 7 PSI
- 14 PSI
The wastegate arrives with the spring configuration specified for the particular unit, with the additional springs included for future adjustment.

Get the Boost Control Your Turbo Setup Deserves
Your wastegate is responsible for controlling one of the most important variables in a turbocharged engine: boost pressure.
Poor wastegate control can mean boost creep, unstable boost, inconsistent power, and a car that's difficult to properly calibrate.
The Turbosmart GenV WG45 HyperGate45 gives you a compact, high-flow wastegate engineered for consistent boost control, installation flexibility, and reliability under extreme conditions.
