When the turbo or turbos are sized properly there is no run away charge temps (heat soak). The HX40 is a upgrade but it still doesn't map well to your engine. Even for a mild Cummins, they are too small. Excellent write up though. The HX40 would work on a low boost combination. When you start pushing it the charge temps will run away.
Surprisingly, I saw no extra heat generated going from 1.0 to 1.4 bar.

What size turbo(s) do you suggest? A modern 60mm seems to way outflow, say a 60-1.

Curious what you think.
