Comp turbo failure less than a mile

This is what I don't understand. I don't recall feeling any type of resistance on the turbine prior to starting the vehicle. My guess to this would be that once the turbo came under boost and heat something changed........Or it happened when I had the bolts all loose to clock the turbo and when I twisted it into its final position I never checked it by spinning the turbine because at this time it's already mounted into the final position and I just ended up putting the air filter on it.
Remember though I was able to drive the car a half mile getting into the boost a couple times with no issues......it ran great no weird noises, spooled up fast....so something changed after the second time getting into boost.

My guess is that you damaged the thrust bearing, allowing the impeller to come in contact with the bowl. But that's based on my experience with industrial blowers, so YMMV.
