235* EOT = Problem?

I towed a 8,000 travel trailer on a 2500 mile trip to yellowstone this last week and saw EOT upto 235* and ECT deltas up to 20* or so pulling steep grades for extended periods of time. Outside temps were just under 100*. I backed off on the throttle to keep temps under 235*.

I'm having all the bulletproofing done this week including head gaskets, arp head studs, egr cooler, oil cooler, stc pressure fitting upgrade. Anyway, wanted to know if these are normal towing temps?

Unloaded I'm running about 195* EOT and 7* deltas.

Yup. You can expect higher deltas when towing. The key is to identify your delta when empty.

Now that I've got her bullet-proofed as noted in my updated signature; what temps should I start getting nervous about? I've spent alot of money, now I want to make her work a little harder and pull a little faster. I've read EOT = 253* is the redline. I don't want to ride the limit, but want to know the upper end of my "SAFE" eot and ect temps.

Thanks much.

You will have a tough time getting it much over 235* if everything is working properly. The truck will defuel when EOT gets to a certain point to protect itself from damage. I can't remember what the exact temp is off the top of my head though.

So is it safe to run all day long at 240* EOT?

Wow I feel better after reading this. I was towing my 10K box trailer Saturday and on one extended hill I saw 225* and 20* delta for a minute and freaked out!
