"The first time you see it seems shocking , but that is how hot they run! I remember popping the hood of my 1979 900 turbo and thinking the thing will melt! Most big diesel trucks have a "pyrometer" which measures the exhaust manifold temperature. That high temp is the reason many people leave the engine running awhile after a long pull to cool down. I always marvel at how the gaskets/diaphrams/o-rings survive the temp."
I don't know if I would agree that that's how they normally run, but maybe it's just that it seems more shocking when viewing it in the dark? I'm still concerned that it happens during pretty normal interstate speeds and even non-interstate speeds. Would an intercooler help at all?
intercooler will likely make it worse. The intercooler is going to cool the intake charge thus allowing you to run more boost.
