I seized my crank bearings on my 800 HO turbo within 300 miles. This was a new crank and freshly packed bearings. The boost blew the isoflex grease out of ALL of the crank bearings. So now I run sealed bearings.
Here is a link to my HO turbo headaches:

Also a few vids on my YouTube channel with a bit more info:
i watched and commented on your video last night .. im going to run 3 psi to start and see what happens i would hope that the seals would hold 3 psi and knowing that this happened to you i will have to keep an eye on it now for sure .. i think you said you were running 7 psi when this happened ? did it blow out the seal behind the clutch and the stator or did it push it out the vents ?
