Tial MVS-A 38mm Wastegate Black
motorsport applications that can't utilize the water cooling ports on the standard MV-S
wastegate. 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
Motorsports, this wastegate can handle the harshest of conditions and give 100%
performance, 100% of the time. It is the choice wastegate of many WRC teams.
With 2 upper and 3 lower air ports you won't even have to rotate the actuator to get to the
air lines. Simply use the most convenient ports and block the others off with included
port plugs. Valve and lower housing are constructed from high temperature alloys for their
unique combination of high corrosion, wear and galling resistance properties. Valve stem
has a wear coating that is resistant to the corrosive effects of lead oxide. Actuator
housing is CNC machined from lightweight billet aluminum which is available color
anodized for a unique appearance.
The MV-S-A utilizes V-Band connections and includes both inlet and outlet mating flanges
and clamps. The stainless steel flanges feature chamfered edges and are
counterbored to make welding simpler. Each wastegate also includes all MV-S-A
The MV series TiAL wastegates also have integrated -4 AN water cooling ports that
cycle a small amount of coolant through the actuator top to keep the temperatures
down in extreme conditions. This feature is not required for typical street car applications
but is a great addition for several scenarios, such as: road racing, low air flow in engine
bay, actuator too close to exhaust components, rotary applications, etc. This feature uses
little coolant so there is virtually no affect on the rest of the cooling system. Fittings are
leak tested after installation from the factory and can be removed if not utilized.
