Default Oil-less turbocharger

Hey guys! So we just had our car show today, and I found something very interesting. Ryan from Moore performance came up with a WRX that he built up, and he was running an intriguing turbocharger from Comp Turbo Technology.

It is basically a normal turbo from Comp, but they use a special high tempature grease in the housing, eliminating the need for oil (still uses water cooling). Ryan said it has worked great, and it is supposed to have about a 50k mile service interval.

Has anyone herd of these before? It seems really neat, it would be nice to not worry about oil draining/smoking, plus you could mount the turbo however you wanted! Would be great for remote mount people too.

Just thought I would pass it along...

It's for packaging reasons, mostly.


Oh, and they absolutely stomp **** out of Garrett in the performance department.

I can understand them in cars where space constraints limit to a low bottom mount manifold, where a scavenge pump is mandatory, but I don't see them as huge news for cars that have space for a nice top mount.

They don't need oil lines BUT they still need water lines.

I read good and bad things about them.
The few bad news were about their reliability. I really would like to hear more high mileage out of them to be convinced.

As now, as far I know (maybe I'm wrong) they don't offer the same trouble-less life as a standard turbo with correct engineered oil system.

IIRC there were some fails, now I don't remember if they were the first ones released or not.

I really would use them if they had no troubles, had some cars in past where the turbo sat too low and I had to quit the project because I never trusted scavenge pumps(until Turbowerx came ).

The point of these is that you can put them ANYWHERE. You wouldnt buy one and use it on a normal manfold. You would buy one and use it on a long runner header, with the turbo hidden under the car, or some such.

Unfortunately, Comp has a serious reliability reputation problem. These turbos might be better than their more conventional stuff, but said conventional turbos are notorious for coming apart every 500 miles.

there are some cool new turbos on the market. check out the new EFR turbos from borg-warner. they have internal gate and built in by-pass valves. there was a guy on a jetski forum i am on that put one on his built motor and they are looking pretty promising.

Anything that reduces points of failure is worth the investment... especially if it was just finding the right grease that's probably some aerospace application that's been around for years. And since water cooling isn't really necessary on a street-car, I can see eliminating at least 10pts of failure/leakage in eliminating the 4 fluid lines.

Yes, a good idea for packaging, but less parts to buy and engineer even if you've got the room. No more "tapping the pan", buying sandwich plates, draining the radiator, etc...

I respectfully disagree with Hustler that discovering an easy way to eliminate oil cooling is a waste of time.

Something like this is what i've been looking for, for my Buell. I've been wanting to do a turbo setup mounted under the bike where the stock muffler is, this would keep a low center of gravity, as well as the clean looks. You can see what I mean in this pic. (mines on the left).



I'm talking mounted under the bike attached right of the end of the header. It would be really easy to mount there. I would need a tiny one, gt15,17,20 etc. Then id just need to set up a water reservoir with a remote pump and hide it somewhere. The nakedness of the bike would make this hard.

Any ideas?

No oil lines would be nice for a rear mount turbo. The cooling lines may still be needed but they are easier to deal with.
