I was wondering what the normal egts are while towing about 5000 lbs, I recently went thru wv mountains on 64 and could not stay at 75 and slowed to 50 up the major hill because my egts went to 1100 and I let off. when I returned home I checked for a boost leak with a automotive smoke machine and only saw smoke coming out my exhaust < I had a loose clamp at the turbo, fixed that and now coming out the tail pipe. > I was running in 60 tow with dp tuner. and did turn off overdrive when it hit 1100 . any think to check before this weekend trip will be helpful thanks

 

1100 is not hot when towing uphill, assuming your pyro probe is in the exhaust manifold.

It is good that you found and fixed the leak. But the temps you were seeing it sounds like it was the down pipe that was loose. Is that correct? Usually a good leak at the up-pipes would shoot your EGT's well over 1300 degrees very quickly.

 

Not far off of mine, only I tow about 12K. Have had some luck with downshifting, raising rpms, but have had to slow down more than once. I also have DP 60t. 1100* by itself isn't too much, except it doesn't leave much room to pass or accelerate. Heat soak can do damage quick.

 

1100 isn't bad. I understand (please someone correct me if this is wrong) that you can run 1200 all day, but don't want to hang out above 1250, though it may be okay to go above it a bit for a few moments passing followed by a good while driving a lower temp.

Taking it out of overdrive to raise RPM should help keep temps lower. Your transmission will appreciate it too when towing heavy.

 

What kind of boost are you seeing?

BTW, 1100* is nothing to be worried about.

 

I don't have a boost gauge yet so I don't know, the truck seems like it has power except with the trailer, I might try a hill or two in stock and see what happens, , I double checked the up pipes and do not see any soot at all around the joints. I am just worried about why I smoked the intake and it came out the exhaust pipe?

 

You have a boost leak if 5000 is making 1100 egt
I tow 14k and barely see 1000.

 

I think the issue is trying to tow 5000 lbs at 75 mph.

 

Altitude makes a bigger difference.

Go high enough and a bone stock truck can hit 1100 degrees empty with absolutely nothing wrong with it.

If he's towing up in the mountains (even if they are just the Appalachian "hills" ), he's several thousand feet above sea level. It's easy to get those temps with 5000 lbs behind.

 

X-2, 7 miles 6% grade southbound I-5 Mt. Ashland. 1000-1100* O/D off, 40T. Ambient 101*, 50-55 mph.

 

Just for reference, I towed 6000lbs 200 miles each way through the Berkshires on I-90 this past week and up the longest grade with the big rigs on the climbing lane with flashers I was able to maintain 60-65mph in OD with EGTs at about 1100, trans never broke 185, boost was constant at about 10-12psi and I wasn't anywhere near the floor on the pedal.

 

well the return trip was a little better, I did pull the long hill in stock mode aand was able to keep some speed with egts around 1050, I have the same trip thru wv at the end of the month with some more gear, do you think the egts at 1200 for 5 miles will hurt the truck the egt probe is in the manifold and the guage is a isspro. I might try to get a boost guage but really wanted the trans guage first. the thought that the launch app would have the trans temp and boost in live pcm data but they are not there. still nobody has answered why smoke from my intake was making it into the exhaust . I am think the turbo seal is leaking on the shaft , I used to get dome turbo surge but do not get that noise anymore.

 

If your seal was leaking you'd have a ton of oil exiting out your exhaust pipe and blowing white smoke while driving.

And FWIW based on what you've posted you don't have an EGT issue.

 

I'd pull all day at 1200.

 

I have for a 1/2 day............... Its still alive.
