TiAL 003908 MV-S 38mm Wastegate V-Band External Turbo Boost Controller

The TiAL MV-S 38mm Wastegate is a compact, high-performance external wastegate engineered for turbocharged applications demanding precise boost control and superior durability. Significantly more compact than TiAL's F38 predecessor, the MV-S stands just 3.7 inches in height, making it an ideal choice for tight engine bays and space-constrained turbo builds.

Key Features:

• 38mm valve diameter for efficient exhaust gas bypass and accurate boost regulation
• V-band inlet and outlet flanges for leak-free, tool-friendly installation and removal
• Three lower air ports and two upper air ports for versatile pneumatic boost control plumbing configurations
• Compact low-profile design at only 3.7" tall — significantly smaller than the F38 model
• Stainless steel construction for high heat and corrosion resistance
• Precision-machined internals for consistent, repeatable boost control
• Compatible with a wide range of TiAL interchangeable springs for customizable boost pressure settings

The MV-S features TiAL's signature V-band clamp system on both the inlet and outlet, eliminating traditional bolted flanges and dramatically simplifying installation. The multiple air port configuration provides tuners the flexibility to run both lower and upper ports for precise dual-port boost solenoid setups, or simplified single-port configurations. Built to TiAL Sport's exacting tolerances, the MV-S delivers reliable, repeatable performance in high-boost street, track, and competition builds.
