WG50 ProGate50 GenV 50mm External Wastegate by Turbosmart
Turbosmart ProGate50 GenV 50mm External Wastegate
If you’re searching for a 50mm wastegate, a ProGate50, or a serious external wastegate for a high-performance turbo build — this is the benchmark.
The Turbosmart ProGate50 GenV is one of the most versatile and widely used 50mm external wastegates in modern motorsport. It offers exceptional boost control authority without the physical size of a 60mm unit, making it ideal for serious street, track and competition builds.
At Walton Motorsport, we frequently specify the ProGate50 for medium to large turbo systems where stable boost control is critical across the entire RPM range.
Why Choose a 50mm External Wastegate?
A 50mm external wastegate offers the ideal balance between:
• Exhaust bypass capacity
• Packaging space
• Boost control precision
• Response stability
For many turbo systems, a 50mm gate provides more than enough bypass volume while maintaining easier installation and cleaner packaging compared to larger 60mm units.
Bigger does not equal more power.
Gate sizing is about control authority — not peak horsepower numbers.
What Makes the GenV ProGate50 Different?
The GenV range was a ground-up redesign, retaining only mounting orientation from the previous generation to allow direct upgrade compatibility.
Everything else was re-engineered.
Key Features:
• Class-leading thermal performance
• CFD-optimised and flow bench validated design
• Nitronic 60 valve guide
• 347 stainless steel body
• 17-7 PH stainless steel springs
• Modular actuator housing with 360° rotation
• Optional liquid cooling ports
• Strap-type V-band clamps
• Collar-locking cap system
The result is improved durability, superior heat management and more consistent boost control under extreme conditions.
Boost Control That Actually Stays Controlled
A properly sized 50mm wastegate helps:
• Reduce boost creep
• Improve low boost tuning accuracy
• Stabilise boost during gear changes
• Improve torque management
• Maintain consistent boost at high RPM
Especially when paired with a high-flow turbo manifold — something we know a thing or two about.
Direct Fit Upgrade for Gen4 ProGate50
The inlet and outlet mounting orientation remains identical to the previous Gen4 version, allowing:
• Direct replacement upgrades
• Easy integration for manifold manufacturers
• No reworking of existing flanges
New technology. Same fitment.
What’s Included in the Box
• GenV ProGate50 Wastegate
• Full spring kit (3, 5, 7, 14 psi)
• One spring pre-installed
• SS316 valve seat
• V-band clamps
• Inlet and outlet weld flanges
• Collar locking tool
• 1/8” NPT plugs and fittings
• Mounting hardware
Everything required for installation is included.
Frequently Asked Questions
Do I need to use the liquid cooling ports?
No.
Liquid cooling is optional and generally only required for extreme endurance or restricted airflow environments.
The GenV already features:
• CFD-optimised heat management
• Thermal isolating ceramic spacers
• One of the most thermally stable diaphragms available
For most performance builds, liquid cooling is not necessary.
Can the actuator housing be rotated?
Yes.
The ProGate50 GenV allows full 360° actuator rotation.
This enables cleaner hose routing, improved heat avoidance and neater engine bay packaging — particularly in tight turbo setups.
Will the GenV ProGate50 fit where my Gen4 did?
Yes.
The mounting orientation remains unchanged for straightforward upgrades.
What size are the boost reference ports?
All boost reference and optional cooling ports are 1/8” NPT.
Stainless hose tail fittings are included, with the option to upgrade to -3AN or -4AN motorsport plumbing.
Is a 50mm wastegate big enough?
For most 500–900hp turbo systems (application dependent), yes.
A 50mm wastegate provides excellent control authority without unnecessary packaging bulk.
Correct sizing depends on:
• Turbocharger size
• Manifold design
• Exhaust housing A/R
• Target boost levels
If unsure, contact us.
Why Buy From Walton Motorsport?
We don’t just resell Turbosmart components.
As a UK-based turbo manifold manufacturer, we integrate wastegates into complete boost control systems daily.
If you’re unsure whether a 45mm, 50mm or 60mm gate is correct for your turbocharger and manifold combination — speak to us before ordering.
Boost control is about system design, not just component size.
