If you’re looking for a reliable external wastegate that has been engineered, tested, and proven to give you reliable results, then you may want to consider a Tial unit. External wastegates can endure extreme temperatures, and because of these reasons, the Tial unit has been crafted from fine alloy materials to provide the user with longevity they can depend on.
Boost can be controlled from two top ports, as well as three bottom ports. At just 3.7” tall, the Tial 38mm MVS wastegate is one of the most compact external wastegates on the market. This Tial unit will come supplied with all the springs, and some wastegates come provided with pre-installed springs installed by Tial, so you may want to verify which springs are installed before installing this part onto your car.
- High temp NiCrFe based alloy is used for the valve and 347SS valve housing will 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, resist “relaxing” at temperature 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 installation. No need to rotate the actuator top at all, plugs included for unused ports.
