So I have a pretty well documented issue with water temps. While waiting to get my freeze plug issue resolved I’ve been kicking around a few things in my head. One of them is EGTs. Running a 110 from CDD and with my setup I can manage EGTs pretty well I think. In 4th gear climbing grade, I can just about push it flat on the floor and hold it there if I want. I get to 1000-1100 maybe a little more on a really long pull. Problem is if I get over 900F water temp really starts climbing. I guess that makes sense to me. I’ve been told you can run these engines at 1000-1100 F all day long and not hurt them. Well, I can’t because I can’t keep it from overheating. So I guess my question(s) for the masses are these.
1. Do you see similar behavior? Should 1000 F really drive up water temp fast?
2. If you see that behavior are you turbo, turbo + IC, or NA?
I’m starting to wonder if the problem really is the IC dumping heat into the rad when I’m working the truck. I know the charge pipes get really hot. I’ve been wanting to measure how hot that is but hadn’t taken the time to measure it. I really only make about 20-22 psi of boost. I suspect it would be more without the IC. Is the IC just really working well and causing a secondary issue? The big fan and 6.4 clutch have helped but I feel like I’m still not quite where I want to be. Maybe I need to shed some more heat elsewhere?
