TiAL 004516 MV-R External Wastegate with V-Band Flanges - 44mm

The TiAL MV-R 44mm External Wastegate is one of the most compact external wastegates available, outperforming larger 44mm and 46mm competitors while fitting in tighter engine bay locations. Only 4.17" tall, the MV-R is engineered for precision boost control in high-performance turbocharged applications and is a direct bolt-on replacement for the legacy TiAL V44.

Key Features:

• Ultra-compact design — at just 4.17" tall, fits where other 44mm and 46mm wastegates cannot
• 5-port air configuration — two top air ports and three bottom air ports eliminate the need to rotate the actuator housing during installation; plugs included for unused ports
• Integrated -4 AN water cooling ports — cycles coolant through the actuator top to manage temperatures under extreme conditions
• High-temp alloy valve with stainless steel valve housing for superior corrosion, wear, and galling resistance
• Nitronic 60 stainless steel valve seat and valve bushing for long-term durability
• High-temperature silicone Nomex reinforced actuator diaphragm
• 17-7 PH stainless steel actuator spring delivers consistent pressure even at temperatures near 900°F (483°C)
• V-Band inlet and outlet connections for fast, secure installation
• 304L stainless steel CNC-machined 12mm thick weld flanges with chamfered edges and counterbored design for simplified welding
• Color anodized 6061-T651 billet aluminum actuator — available in Silver, Red, Blue, Purple, or Black
• All stainless steel hardware throughout
• Made in the USA

• MV-R Wastegate Assembly
• Inlet V-Band clamp and flange
• Outlet V-Band clamp and flange
• CNC machined air fittings and -4 AN water cooling fittings
• Plugs for unused air ports

The TiAL MV-R is a proven choice for street, track, and motorsport builds requiring reliable, repeatable boost control in a compact, high-quality package.
