TiAL 002390 MVS 38mm V-Band External Wastegate with All Springs - Black

The TiAL Sport MVS 38mm V-Band External Wastegate (Part# 002390) is a precision-engineered boost control component built for high-performance and motorsport turbocharged applications. Featuring a compact V-band inlet and outlet design, the MVS stands only 3.7 inches tall, making it the most compact external wastegate in its class and ideal for tight engine bay installations including twin-scroll and dual-wastegate setups.

This Black anodized unit ships complete with all seven optional springs, inlet and outlet V-band clamps and flanges, CNC-machined air and coolant fittings, and plugs for unused ports — everything needed for a complete installation. Integrated -4AN water cooling ports allow coolant to circulate through the actuator housing, protecting the diaphragm and internals under extreme heat conditions.

Key Features:

• 38mm valve diameter — high-flow external wastegate for precise boost control
• V-band inlet and outlet — flexible installation orientation and simplified fabrication
• Only 3.7" tall — ultra-compact design fits in extremely confined spaces
• Haynes HR120SS alloy poppet valve and stainless steel valve housing for maximum durability
• Nitronic 60 stainless steel valve seat and bushing resist high-temperature binding and distortion
• High-temperature silicone Nomex-reinforced actuator diaphragm for long service life
• 17-7 PH stainless steel actuator spring — maintains consistent pressure up to 900°F (483°C)
• 3 lower pressure ports and 2 top air signal ports — no actuator rotation needed during install
• Integrated -4AN water cooling ports for coolant-assisted actuator temperature management
• Black anodized CNC-machined aluminum actuator top
• All seven springs included — covers a wide range of boost pressure targets
• 304L stainless steel mating weld flanges included
• All hardware is stainless steel
• Designed and manufactured in the USA

What's Included:
