Curious as to how a turbo blanket, which confines heat mostly to the turbo increases performance? Isnt the whole point to reduce turbo temperatures and not increase them with a heat shield or blanket. I would think that a heat sink or fan on the turbo would be more effective to " remove" heat. I know with my supercharged cars , I try to make the SC run as cool as possible.

A blanket may reduce overall underhood temps to the detriment of the actual turbo running hotter. I know when I run the car hard that I pop and prop the hood for an hour or so to let it all cool down , particularly in summer heat.

I have been skimming through this thread and am wondering why heat seems to be a problem for the original poster. I live in Sydney and 90F is a nice summer day here and I have seen 117F on my outside temperature. In the heat the engine seems to run really great. I have the temperature in C on my DIC and the diesel runs 20C cooler than the petrol engine and changes very little between summer and winter. Perhaps because of the DEF, which my car doesn't have, your engines run hotter?

I was wondering as well why heat is an issue. My car runs great in FL, where heat ( and humidity) in the summer are a constant issue. We don't typically see over 100F , but 95-97 F with relative humidity >90% are present daily. In fact, it's not until the engine is quite toasty or at operating temp that it runs its best according to my butt dyno. I've also spoken to long haul truckers who've stated heat is typically not an issue with their rigs. It's the cold that does em in ( gelling etc.).

As as to DEF, I don't believe that has anything to do with it as that's way after the combustion process and would be more an exhaust issue. Anyone else have issues with heat and their CTD??
