the truth about max egts

ok i know 1250 is doabe all day long and you can go higher for short bursts but whats the real max upper limit. on a hard pull up a big hill at around 1300 im letting go of the throttle. what is safe for a short time. if you hit 1400 for a minute or two is it going to hurt your motor? ive tried to search for an ansewer but i can only find the same q and a over and over. if 1250 is the absolute max ever seems like there would be alot more dead diesels. sorry if this has already been asked but im very interested in this and cant find a real ansewer for the short bursts max temp.

does no one have an opinion on this ?

Been rehashed many times....1250 should be max towing. SHORT as in a few seconds burst higher..can be done.

add an intercooler, or a bigger turbo

From what i understand after asking around and doing some research. Around 1250 is the highest you want to go to be safe. I was told by a member here a while back once you start getting Close to 1300 and up the heat generated will start softening the metals and allow distortion which leads to a "found on road dead" ford. Exhaust manifolds warp/crack, up pipes start leaking, turbo wipes out and internals start to weaken due to internal temps. Just because egts are 1250 doesn't mean internal temps are not higher. Which leads to overheating, blown head gaskets and so on. I don't remember exact numbers but combustion temps are considerably higher so its one of those train wreck effects, one car derails and chances are more will follow but either way it ain't good.

i always back out at 1250-1300 but im just wondering if an occasional run a little higher is ok. i love my truck and do not want to hurt it but i see guys without guages or drag racing and then towing their camper 500 miles and it just makes me wonder if there is any room to wiggle a little. im still going to shoot for no more than 1250 but if im going to top a hill and need to push for a few seconds will i cause damage to my truck.

Well higher temps do happen and some people have done this with no problems. I have seen1320 towing but my alarm goes off at 1300 so i try to stay under, short bursts as in seconds might not hurt anything but it also depends on the truck. Not saying its good for the truck but i can't say it will hurt. A friend of mine hit 1300 with his obs 96 7.3 and the results were not good and like i said i have been higher so i can't explain why, all i can do is tell you he wasn't as lucky as i was. So 1250 is pretty much the default answer because that's what most people haven't had any problems with.
