TiAL 004324 MV-R External Wastegate V-Band - 44mm

The TiAL MV-R 44mm External Wastegate is an ultra-compact, high-performance boost control device engineered for turbocharged applications. Measuring just 4.17" in overall height, the MV-R is one of the most compact 44mm external wastegates available, allowing installation in tight engine bays where other wastegates simply won't fit. It is a direct bolt-on replacement for the legacy TiAL V44 wastegate.

Key Features:

• Ultra-compact design — only 4.17" tall, fits where competing 44mm and 46mm units cannot
• V-Band inlet and outlet with included mating flanges and clamps for leak-free, secure fitment
• 5-port air configuration — three lower ports and two top ports eliminate the need to rotate the actuator housing during installation; plugs included for unused ports
• High-temp NiCrFe alloy valve with 347 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 for reliable performance under sustained boost
• 17-7 PH stainless steel actuator spring maintains consistent pressure and resists relaxing up to 900°F (483°C)
• Integrated -4 AN water cooling ports cycle coolant through the actuator top to manage temperatures in extreme conditions; leak-tested from the factory and removable when not needed
• CNC machined 304L stainless steel flanges with chamfered edges and counterbored design for simplified welding
• Color-anodized 6061-T651 aluminum actuator available in Silver, Red, Blue, Purple, or Black
• Spring pressure range covers 4.35 psi (0.3 bar) up to 24.66 psi (1.7 bar)
• All stainless steel hardware throughout
• Racing valve stem with wear coating resistant to corrosive lead oxides when running leaded fuels

What's Included:

• MV-R Wastegate Assembly
• MV-S Valve Seat
• Inlet V-Band Clamp & Flange
• Outlet V-Band Clamp & Flange
• 2x TiAL -4 AN Removable Water Fittings
• 2x TiAL Air Fittings
• Plugs for unused air ports
• All 7 actuator springs

The TiAL MV-R is optimized for maximum actuator-to-valve area ratio, delivering precise boost control and wide dynamic flow capacity. Whether for a street build, road race application, or all-out motorsport use, the MV-R sets the standard in 44mm external wastegate performance and reliability.
