I've got a '78 Bus with AHU installed. Runs pretty well, though the IATs are quite a bit higher than, say, in my Golf. Not uncommon to see close to 180 degrees at times of high boost for a little while.
I'm currently running a watercooled intercooler with a too-small radiator (because I wanted it to fit on the front suspension).
But under normal circumstances it works "Ok, I guess"but I have wondered recently about going back to the air to air intercooler because it did just about as well and would be a lot simpler of a system.
I had issues on a recent trip with hoses popping off because I decided I'd use clear reinforced vinyl hoses instead of rubber, so I could see air bubbles. Bad idea-as the vinyl heated up it started popping off connections.
I made it to the camp spot and changed to all rubber hoses and didn't have any more problems, but did wonder along the way...
What would have happened, if anything, if I kept driving with no water in the system. The couple times that the system drained, I saw intake temps get up to well over 200 degrees, maybe 230 or possibly more.
So the, now mostly theoretical, question is, if the engine coolant temps stay in check, and the EGTs stay in check, would those super-high intake temps hurt anything? Maybe not forever, but how about over a few hours so I wouldn't have had to show up to camp as late?
