Tial Wastegate 38mm MVS 1.0 bar, 14.5 psi (Black)

(Product Code: 95053-BLK)


The TiAL® MV-S Wastegate is the most compact 38mm wastegate on the market today. Standing just 3.7" high, this external wastegate can be mounted in very tight locations. With two upper and three 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 the included port plugs. The valve and lower housing are constructed from high temperature alloys for their unique combination of high corrosion, wear and galling resistance properties. The actuator housing is CNC machined from lightweight billet aluminum which is available color anodized for a unique appearance. All TiAL® wastegates are designed to optimize actuator-to-valve area ratio to provide maximum control and a wide dynamic flow capacity.

The MV-S 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 actuator springs. Each valve includes all necessary springs so to run pressures from as low as 4.35 psi (0.3 bar) up to 24.66 psi (1.7 bar). All TiAL® springs are constructed from 17-7 PH Stainless Steel for consistent pressure delivery, even at high temperatures. 

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.
