This MV-S-A 38mm unit is designed specifically for Motor sport applications that can't utilize the water cooling ports on the standard MV-S waste gate. The MV-S-A or "long neck" has the standard 38mm valve but also has five heat fins that separate the casting from the actuator top. Born into the world of Motor sport this wastegate can handle the harshest of conditions and give 100% performance 100% of the time. It is the choice waste gate of many WRC teams.
