Tial MV-R, TurboSmart Hypergate 45, Precision 45 External Wastegate Comparison

Tial MV-R, TurboSmart Hypergate 45, Precision 45 External Wastegate Comparison

6th Dec 2021

Some quick physical comparison of the three popular wastegates commonly used.
All three share a 45mm valve.
One thing you will notice is how much smaller the TurboSmart heat sink and diaphragm is compared to the other two.  Another feature is the dished valve on the TurboSmart wastegate which is there for better air flow design, allowing for better control.

Height wise, you can see that Tial MV-R is the shortest barely by couple mm.

Side profile, all three measure almost same from flange to rear of the body.

Diameter of the top:
Tial = largest diameter followed by the Precision then TurboSmart with the most compact design.

You can see the dished valve on the TurboSmart in the middle versus the flat valve on the other two.
