Turbosmart TS-0553-1102 GenV HyperGate45 Motorsport 45mm External Wastegate 14psi Black

The Turbosmart GenV WG45 HyperGate45 Motorsport is a cost-effective 45mm external wastegate designed with extreme temperatures and huge thermal demands in mind. Based on the modular architecture of the GenV range, the Motorsport version features an extra CFD-driven heatsink built-in that is proven to dissipate more heat and further isolate the actuator housing from thermal stress. This motorsport-grade wastegate is engineered for endurance racing and extreme boost applications where thermal management is critical.

Advanced Thermal Management:

• CFD-designed and real-world validated heatsink between the wastegate body and actuator for greater thermal stability in extreme environments
• Ceramic isolator between body and actuator combined with increased distance and convection cooling to eliminate harmful heat transfer
• Optional liquid cooling provision for additional thermal protection
• Enhanced valve and guide cooling extends service life in demanding conditions

Key Features:

• Highest flowing 45mm external wastegate of its kind
• CFD optimized and validated in-house for maximum flow and thermal management
• Nitronic 60 valve guide and high-temp 347 stainless steel body construction
• 17-7 PH stainless steel springs for superior fatigue resistance
• Unique collar-locking system with 360-degree rotatable actuator housing for easy reference hose routing
• 1/8" NPT reference ports for boost signal connection
• Strap-type V-band clamps for secure inlet and outlet connections
• 45mm V-band fitment for direct mounting to external wastegate turbine housings

What's Included:

• GenV WG45 HyperGate45 Motorsport wastegate unit with 14psi blue outer spring installed
• Complete spring set: 3psi (orange inner), 5psi (yellow inner), 7psi (green middle), 14psi (blue outer)
• Locking collar tool for easy spring changes
• Stainless steel 316 valve seat
• Strap-type V-band clamps for inlet and outlet
• Weld flanges for inlet and outlet fabrication
• Hose tail and blank fitting kit
• Turbosmart decal

Direct fit upgrade to all Gen4 Turbosmart wastegates featuring backward-compatible mounting orientation. Provides extensive user configurability, world-leading extended thermal performance, fatigue resistance, and best-in-class flow performance for optimum control and longevity. Designed for professional motorsport applications including endurance racing, time attack, and high-boost competition builds where reliability under extreme conditions is non-negotiable.

Application Note: External wastegates require a custom exhaust manifold or turbine housing with external wastegate provisions. Professional installation and ECU tuning are required for proper boost control setup. This is a race-only product not legal for use on emissions-controlled vehicles in California or other regulated areas.
