TiAL 003763 MV-S 38mm External Wastegate with V-Band Flanges

The TiAL MV-S 38mm External Wastegate is a high-performance boost control solution engineered for turbocharged applications where space is at a premium. Significantly more compact than its F38 predecessor, the MV-S stands just 3.7" tall and features V-Band inlet and outlet connections for straightforward installation. The five total air ports — three lower and two upper — allow for flexible routing of pressure sources and boost controllers without ever needing to rotate the actuator top.

Built from premium materials throughout, the MV-S is designed to withstand the extreme heat and pressure demands of forced induction builds. The actuator housing is CNC machined from lightweight billet aluminum and is available in multiple color-anodized finishes. Every unit ships with all actuator springs included, allowing boost pressures from 4.35 psi (0.3 bar) up to 24.66 psi (1.7 bar) right out of the box.

Key Features:

• Ultra-compact design — stands only 3.7" tall, ideal for tight engine bays and twin-scroll dual-wastegate setups
• High-temp NiCrFe alloy valve with 347SS valve housing for superior corrosion, wear, and galling resistance
• Nomex-reinforced high-temperature silicone actuator diaphragm for durability under extreme conditions
• 17-7 PH Stainless Steel actuator spring maintains consistent pressure and resists relaxing at temperatures up to 900°F (483°C)
• Nitronic 60 Stainless Steel valve seat and valve bushing for long service life
• 304L stainless steel mating weld flanges with chamfered, counterbored edges for easier welding
• V-Band inlet and outlet connections — mating flanges and clamps included
• 3 lower + 2 upper air ports — no need to rotate the actuator; plugs included for unused ports
• Integrated -4 AN water cooling ports to manage actuator temperatures in high-demand applications such as road racing
• All stainless steel hardware throughout
• Color-anodized billet aluminum actuator available in Silver, Red, Blue, Purple, and Black

• MV-S Wastegate Assembly
• MV-S Valve Seat
• Inlet V-Band Flange and Clamp
• Outlet V-Band Flange and Clamp
• (2) TiAL -4 AN Removable Water Fittings
