+1. When the bearing starts to get loose and wobble, and they all do, your metal impeller with happily start machining your engine cases, doing damage that may not even be fixable. There is a reason Porsche used composite impellers...........

I've seen the results of a metal impeller milling a block.

Not sure if they ever got that block to work again (next time I see my mech I will ask).

Either way -- not pretty.
