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.​

Technical Specifications

Application

• Suitable for motorsport builds, time attack, drift, drag, and highly advanced street vehicles where precision boost control and compact design are critical.​
