possible mod to turbo/compressor?

[Whitmore]

First off I am not a turbo guro .



Has anyone ever considered a water jacket between the turbo and the compressor housings to add value for heat transfer to the bearings as well as the oil in the galleries ?

I know this would require a whole new casting with water jacket and also a longer comon shaft... ... ... . just curious, Kevin

What about a small oil cooler in the oil feed path to the bearing.

With the extreme temperatures involved it would seem the coolant would have to be under extreme pressure not to boil (a lot more pressure than the engine cooling system is). In addition, the stress on the metal caused by the temperature difference between the interior and exterior of the housing would seem to necessitate a pretty hefty casting. What would you hope to gain by this??

water cooled

I bought a new in 85 a Toyota turbo diesel 4x4 and it had a water cooled turbo in it. I drove it for a long time. It was not inner cooled or direct injection. It had a 5 speed. I drove it for 15 years and never installed a clutch or pressure plate.

The starter was the same type as a dodge and had the same contacts as a dodge. I found this out when I ordered some and when I looked at them I realized that I had several in my tool box all ready. The clicking starter was found to be the relay not the contacts that I have pulled and cleaned and dozen times before I figured it out. Live and learn . Jim

Why

Gains of a water cooled turbo would be longivity or life, another would be to help prevent cooking of the oil incase of early shut down or propper cool down... ... ... . Kevin

If I'm not mistaken, there are some water-cooled turbos on the market already. Matter of fact, a guy I work with has a turbocharged motorcycle that has a water-cooled turbo. He says it really overloaded the cooling system on his bike.



There are also a few diesel cooled turbos. I've only seen one in person. Looked like it would give a lot of problems.

Water cooled

The GMC SYCLONE has a water cooled turbo! It was a really neat to see how it was set up also! So it can be done.

 

[Steve St.Laurent]

I'm pretty sure that the Duramax has a water cooled turbo on it.

There are many many applications that use a water cooled turbo bearing housing.

Virtually every Chrysler turbo engine, the 2. 2L, 2. 5L, the Mitsuibishi turbos, and so on are all water cooled turbos.



It is actually a water jacketed turbine bearing housing to help reduce the running temperature of the bearings during high boost and also during cool down.



It makes the cooling system plumbing slightly more complicated but not that much. It would be quite simple to put a coolant line from the 12 valve hard steel line to the turbo.



Our set up does not seem to need the added cooling due to the increased oil sump capacity (as compared to a 4 cyclinder turbo gas motor) and a normally adequate cooling system capacity.
