COMP Turbo Oil-Less Weird Noise

If there was issues with the rotation assembly contacting any surface of the compressor or turbine, you would not hear it spinning like this.

It is the ball bearings that are making the sound.

So if I got this right; When servicing the unit normally every 3000 miles you give it 5 shots. But now not 1000 miles later they're telling me to give it 8 shots of grease.

That doesn't seem right.
