100,000 RPM?!!
Yup, I'm very eager to see what bearings you use!
Every inch-pound of friction will release 1200 watts of heat at that speed.
Considering all the clever stuff you've come up with before, I bet you can overcome that, too.

Most if not all turbo chargers have an oil injection system that runs off the crankcase oil. They fail when the oil fails to flow to them. Will you have an oiler of some sort to help keep it cool.

Steven, I have done some research into oilers for miniature bearings. In combination with a floating high temperature teflon seals they work well into the 200,000 sm range. I find more problems in the weight of my oil. I need a turbine oil. I have also looked into carbon graphite, they can take the heat but the shaft has to be very hard around 400 for long life. I can't work without precision grinders. Thanks for the input.
Joseph.
