TiAL 003979 MV-S External Wastegate V-Band Stainless Steel - 38mm

The TiAL MV-S 38mm External Wastegate is a high-performance, compact boost control solution engineered for turbocharged applications demanding precise and reliable boost pressure regulation. Significantly more compact than the previous F38 model, the MV-S stands just 3.7 inches in height, making it ideal for tight engine bay fitments without sacrificing performance.

Constructed from premium stainless steel, the MV-S features a durable, corrosion-resistant body built to withstand extreme heat and high-pressure turbocharger environments. The V-band flange design on both the inlet and outlet simplifies installation and ensures a leak-free, secure connection with minimal effort.

Key Features:

• 38mm valve diameter for efficient exhaust gas flow and precise boost control
• Compact design at only 3.7" in height — significantly smaller than the F38 predecessor
• V-band upper and lower flanges for easy, tool-friendly installation and removal
• Three lower air ports and two upper air ports for flexible pneumatic boost controller connections
• Stainless steel construction for exceptional heat and corrosion resistance
• Interchangeable springs allow for tunable boost pressure settings
• Suitable for both street and competition/racing applications

The TiAL MV-S is a favorite among performance tuners and racers for its combination of compact packaging, precision engineering, and straightforward installation. The multiple air port configuration makes integration with boost controllers and solenoids simple and flexible, allowing for fine-tuned boost management across a wide range of turbocharged builds.
