It's a multiviscosity grease. At temp it flows like an oil.
The CHRA has a larger flow area for coolant.
There is a local guy who had one. I haven't talked to him directly and this is 2nd hand info but, from what I'm told he ran the turbo for about 6 months and it ate the bearings. It was returned to Comp for analysis. I'm not sure what's happened since. I do know that he's since switched back to a traditional oil/coolant BB turbo.
IMHO, while a novel approach and a good US based company, I just don't trust the oil-less turbo designs. I'm far more confident in using tried and proven designs, which, IMO, Comp does quite well with their BB designs.
