Turbo Blanket - University of Austin testing
I just wanted to share this link for fruit of thought.
https://repositories.lib.utexas.edu/...=1&isAllowed=y
TL;DR is, "oil coking" fear was shown to be negligible in lab testing; regular benefits of heat shielding and small gain in spool time during tip-in loads.
I am unsure if this controlled lab testing concluded what is the case in the real world; many people may have anecdotal data yet relative personal experience. Saying this, I think it is comfortable to conclude that turbo blankets don't have the astounding negatives of increased oil temps as I have seen preached before based on conjecture and the delta of oil temps may even be negligible to non-existent-- with then a statistical gain in tip-in spool time/torque.

also noteworthy, the testing was done on a diesel and not a gasoline motor, which would change EGT things. Not apples to apples, but a good data point.

I recently picked up a 124 Spider and there are lots of threads on this on their forums. I actually just read the link provided in the OP today on that forum. It convinced me and PTP happens to make a direct-fit blanket for the 124.
I think the 124 won't have bad side effects because it has a pump that will pump coolant through the turbo, even after shut-down.That will get it down to whatever temp the ECU sees as acceptable, so oil coking should be nearly impossible.
