i was looking into this as i want my new engine build to be perfect.
what he said about 'compressor stall'

Stall has nothing to do with turbo speed, its aerodynamic stall i.e. flow separates from the blades creating transient surge (fluttering noise). Unless you're going to run 3bar+ of boost pressure this shouldn't kill the turbo excessively quickly, put the BOV in the bin and be done with it.

so it seems the shaft/blades dont stop spinning.
