I am not sure if there is a thread on this but i would like to know the benefit between a Water-cooled wastegate Vs a regular wastegate.

 

Keeping the diaphragm from degrading and helping the valve not overheat and bind... This is all just my opinion. You must be looking at the new mvs/mvr I assume...

 

More plumbing to do... Get something quality and rebuildable. I read about this, but has anyone even done it?

Just stop overthinking and get a nice manifold & external Jay

 

the new Tial wastegates have water cooling ports, but that doesn't mean you have to use them. If it were me I would run without the water cooling unless you have a diaphragm fail very quickly.

 

I think a heavily road raced rotarary or maybe a "texes mile" one, would be some of the few applications where this could really be beneficial.


It is a good idea but I don't feal it to be needed, especially in the automotive/street world. I try to keep things as simple as possible and to me, putting more water lines in that high heat area is just not a needed.

I have a Tial 44mm air cooled wastegate on my roadrace turbo II with a GT35R. I've seen egt's in the 1650 range for close to an hour straight without issue. I don't think a water cooled wastegate is anything more than another place to leak fluids as long as you have some airflow past your air cooled unit.

I have installed the Tial MVR with the water ports which you dont have to use. More of a pain hooking them up.

 

Sounds like a good idea but ive never had a problem using our own gates at 30psi for 3-4 hours at a time. Maybe on a 24 hour race car or something like that it would be useful.
