TiAL TIA-002957 – MV-S-A 38mm External Wastegate

The TiAL TIA-002957 MV-S-A 38mm wastegate is engineered for motorsport and high-performance turbocharged applications requiring ultra-precise boost control under demanding thermal and mechanical loads. As an evolution of the acclaimed MV-S series, the MV-S-A variant is specifically designed for professional racing and extreme street builds where water-cooling ports are not utilized.​

Key Features

  • Compact 38mm V-band wastegate – enables flexible and tight fitment in crowded engine bays without sacrificing flow.​

  • Investment-cast 347 stainless steel valve body – provides exceptional thermal stability and resistance to corrosion in severe exhaust environments.​

  • Nitronic 60 stainless valve seat and stem – ensures remarkable wear and heat resistance under prolonged high-temperature operation.​

  • Three lower and two upper pressure ports allow for diverse boost signal routing and precise actuator control.​

  • Universal V-band flanges (1.75" OD for inlet, 1.50" OD for outlet) and hardware included – simplifies installation and ensures reliable sealing with minimal restriction.​

  • Black anodized finish for stealthy appearance and increased corrosion resistance.​

  • All spring rates included, adjustable boost control from 0.3 up to 1.7 bar (4.35–24.8 psi) out of the box.​

  • High-temp silicone-reinforced actuator diaphragm – allows precise boost management under extreme conditions.​
