Yeah, I've been looking at Comp Turbos. How do they compare to your normal oil-fed turbo (comparing like for like housings, turbines etc.) in terms of reliability, spool speed, flow and power output?

from what i have heard spool and reliability are very good. power output matches or exceeds pretty much anything of similar design. my tuner uses them on one of his mates cars, so far he has been very impressed.
Sounds like a really good solution for the cramped Soarer/SC400 engine bays, as you can mount them in virtually any position since you don't need to gravity drain the oil lines.
Very interesting turbo with no oil. After reading on its website, it uses the grease in the bearing (it sounds like an electric fan) and coolant water to cool the bearing. I wonder how often the grease needs to be changed, and how long the turbo lasts.
If these really do have acceptible reliability they will be outstanding for many uses especially low mount and remote mount where a pump is normally used.

I think they have 2 versions. One is standard oil turbo, and the other is upgraded to oiless for $600. So the price is only for oil turbo plus $600, if it's to be oiless. I'm wondering if I can send in my turbo to be oiless.
I like that the bearings are re greasable. Thats definently a big selling point. If the turbo is top mount, changing the grease every 2 weeks or so doesnt sound to laborsome. I always wanted to give turbocharging a try and the idea of not requiring oil feed/drain lines w/ tuned restrictor valves, and engine oil heat soak definently simplify the process and reduce variables. Tap a coolant circuit and off you go. Obviously heat will be an issue any way you cut it. In the end, requiring one less step/variable to a FI application is progress.
I didnt scope out all their models but if they offer a twin scroll design im very interested.
