That was translated from Russian?

So does it spool faster?

Re: Oil-less turbochargers
 

Im thinking it would have to be a fluid based grease? Not like wheel bearing grease or nothing even though that kind of grease seems to get the job done?

These have been used on snowmobile turbo kits to save the weight and hassle of an oiling system.

Re: Oil-less turbochargers
 

I thought that the snowmobile turbo's like the aerocharger's were just a self contained oiling system. Rather then an oilless turbo? I guess I havnt looked at many other then what the skidoo guys r using. I wish I could run e85 in my sled without blowing the crank seals out :(

Re: Oil-less turbochargers
 

From what it sounded like to me in this article, it is just a self contained/sealed oiling system. It's just not having to be fed oil like we are used to.

Is that what everyone else is getting out of it?

Re: Oil-less turbochargers
 

there is no grease, it rides on ceramic ball bearings. there is also no thrust plate.

eh, sounds nice (but so does snake oil)

I'd be more confident in it if it was an OEM using it.

I like how they port their compressor housings. The three wide ports sure do have a pretty mouth.

Re: Oil-less turbochargers
 

It is nice to see an advance in turbo technology. Super charger land has had self contained oiling systems for a long time now, and self contained oil systems on small turbo setups for the last few years.

I would expect little to no gains on spool up, but between shifts this would help the inertia of the compressor/exhaust wheel.
