Genuine TiAL Sport MVS-A 38mm unit is designed specifically for applications that cannot utilize the water cooling ports on the standard MVS wastegate. The MVS-A has a 38mm valve but also has heat isolating and dissipation fins that separate the casting from the actuator top. This wastegate can confidently handle the harshest of conditions. It is the wastegate of choice for many WRC and Grand-am teams. Available in all 5 TiAL colors silver, red, blue, purple and black.
Specs & Features:
• High temp NiCrFe based alloy valve and 347SS valve housing offer longer product life compared to competing designs
• High temperature silicone Nomex reinforced actuator diaphragm
• 17-7 PH Stainless Steel actuator spring gives consistent pressure at high temperature and resists "relaxing" up to 900F (483C)
• Nitronic 60 Stainless Steel is used for the valve seat, and valve bushing
• All Stainless Steel hardware
• Mating weld flanges are 304L
• Color anodized aluminum actuator (Silver, Red, Blue, Purple, Black)
• 3 lower ports and two top ports for easy install, no need to rotate the actuator top at all, plugs included for unused ports.
• V-Band inlet and outlet make install easy, flanges and clamps are in the box!
• 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 such as road racing. These are leak tested after installation from the factory and can be removed if not utilized.
• Five heat sinks raise the actuator top away from the casting to dissipate heat when water cooling can not be used
• Designed for Motorsport / Road Racing
MVS-A Wastegate:
• Flange Materials: 304L Stainless
• Pipe Size for Inlet Flange: 1.75" OD
• Pipe Size for Outlet Flange: 1.50" OD
• Thread Air Ports: M10 x 1.0
• Thread Water Ports: M8 x 1.0
Racing Valve System:
The MVS-A wear coating is resistant to the corrosive effects of lead oxide which is present when running leaded racing fuel.
TiAL V-Band Clamps:
• V-Band clamps and flanges are manufactured in house at TiAL Sport.
• CNC machined stainless steel clamps and flanges ensure a secure and pressure tight fit.
Water Cooled Actuator Top:
• Patent pending water cooling.
• Two -4AN water ports.
• Coolant passes through actuator bottom and has very little affect on cooling system as a whole. The water cooling on the Tial MVR is not a mandatory hook up. Only an added available option if you want to use liquid cooling.
