Who has the fastest /6 here

I have before and no one has said anything about having a slant with one. Ball bearing supported shafts, instead of bushings. Ultra light impellers for quick spool up. Just look at any diesel performance site. Those are the type turbos I am talking about. Properly sized, of course.

The T60-1 used on the Rampage had all of those features. The Simca had ball bearings but not the lightweight option on the impeller.
