The TiAL MV-R 44mm Wastegate represents the pinnacle of compact design and precision boost control for turbocharged applications. More compact than any current 44 or 46mm wastegate on the market, this ultra-compact external wastegate measures only 4.17 inches high, making it ideal for tight engine bay installations where space is at a premium.
Advanced Port Configuration:
Two top air ports and three bottom air ports provide easy installation and optimize boost control without requiring actuator rotation. The MV-R includes plugs for all unused air ports, ensuring a clean, leak-free installation. This wastegate is a direct bolt-on replacement for TiAL's legacy V44 model, making upgrades straightforward for existing TiAL users.
Premium Construction:
- High temp NiCrFe based alloy valve and 347SS valve housing for extended product life
- High temperature silicone Nomex reinforced actuator diaphragm
- 17-7 PH Stainless Steel actuator spring resists relaxing at temperatures up to 900°F (483°C)
- Nitronic 60 Stainless Steel valve seat and valve bushing
- 304L stainless steel mating weld flanges
- Color anodized aluminum actuator available in multiple colors
Integrated Water Cooling:
Integrated -4AN water cooling ports cycle a small amount of coolant through the actuator top to maintain optimal temperatures in extreme conditions such as road racing, low airflow engine bays, or applications with the actuator mounted close to exhaust components.
Complete Kit Includes:
- MV-R wastegate assembly
- Inlet V-band clamp and flange
- Outlet V-band clamp and flange
- CNC machined air and coolant fittings
- Plugs for unused air ports
- All necessary springs for boost pressures from 4.35 psi (0.3 bar) up to 24.66 psi (1.7 bar)
The V-band inlet and outlet design simplifies installation and exhaust fabrication. Stainless steel flanges feature chamfered edges and are counterbored to make welding simpler. Designed for universal turbocharged applications, the TiAL MV-R delivers professional-grade boost control for both street and motorsport builds.
