Very interesting on the temps.  Now if we can get some of the other turbo guys to give some readings, we might be able to confirm this, though as an instrument technician, I trust your readings more than most.  
You'd think so wouldn't you, but as exhibited by a few other questionable choices, my data should still be subject to peer review.
BTW, I'm actually an Instrument Mechanic (5th year apprentice). Instrument Tech is just a 2 year course with no practical experience.
 
Sorry to hear about the ribs.  The little girls you play against are growing up I guess :-)
Fortunately the broken ribs came from a crushing body check from a monster of a man, so I will get an opportunity for retribution, with little consequence from the refs. Trouble with playing against girls is that they can get away with blatant hooking & slashing, but you can't retaliate at all or the the refs call everything.
    Sigh... why can't they stay in the kitchen ;-)
Kidding of course.... but don't let your wives read that.

    However I can confirm that there was a very large delta T across the turbo, and that the temp drop before the turbo is approx. 50F/inch. I have thermocouples installed at each exhaust port, then another a few inches further down right at the turbo inlet, then another ~10" after the turbo outlet (pics are in the archives if interested). I was very surprised at this temp drop myself so swapped around positions of the T/C's to confirm the temps.
    Strange but true.

Good to have you back.
