I have an 06 cummins with the edge juice w attitude, and a 5" turbo back exhaust. Yesterday I was towing my boat up a steep hill, and egt's got up to 1350 while engine temp got up to 212. Egde started alarming and freaking out! Is that really its max temp's or would it be safe to push it more.
Truck was easily handling a 21' foot boat but the temps got too high... Thanks!
1250 really is as hot as you want. Unless you want to rebuild your engine sooner then you want. Anything hotter at a constant temp your pistons start leaving metal behind on your cylinder walls, and the blow by starts getting heavy. Hope this helps
1350 wont hurt it, these motors are designed to go higher for emissions. my 07 would see 1500 stock egt's climbing loaded. 210 is nothing but a little over the middle and if the temps are hot like around here it wont take long to reach 212 at idle.
Well as far as to my knowledge the pistons are still made out of the same metal. They have not changed the melting point of aluminum. As for the emissions its building that heat outside the cylinder to clean DPF. Thats why your pyrometer is picking up the high temps. :confused013:
Where is your pyrometer mounted before or after the turbo. My dad has his mounted directly outside the exhaust port on his 04 Dmax but mine is post turbo. Big differences between the two temps. I know its kinda apples to oranges with the chevy vs cummins. But the mounting place for the pyrometer does have a significant affect on temp
I see 1250 pretty regularly with my probe in the manifold, 1250 post turbo may be a touch high on a long pull. What gear were you in? What mph? Manual or auto?
Yea there is a big difference in readings but when they are running DPF it wont make a lot of difference do to the regen process. The high EGT's are due to fuel being injected in the exhaust stroke and they do reach levels of 1500 Degrees to clean out DPF, The temps will be high from exhaust manifold to DPF

Hm... Even more confused now Egt probe is on the exhaust manifold #6 cylinder. I imagine that this is where it would be the hottest! I believe I was driving in 3rd gear.
It is unbelievable to me that this truck has all this power, but can't use it due to the temps. I was only pulling a 3500 pound boat, scared of what will happen with a 30 foot 5th wheel...
Oh yeah it is an automatic.
So considering the probe placement, what do you guys think? What is the temp I can be confortable at while climbing a steep hill for a few minutes. Both egt and engine..?
1400+ degrees isn't unheard of on a completely stock '06. You start getting into trouble when you add timing. 2006 5.9s do NOT have DPFs and the melting point of pure aluminum is completely irrelevant because the pistons are made of an aluminum alloy. I'm not sure what the Edge does for advanced timing, but 1350 with stock timing isn't bad. I wouldn't let it go over that for extended periods though. I've seen 1550 on my truck for brief spurts with stock timing and heavy programming. My probe is in the manifold.
I wouldn't worry much about 1350 for a while but you might wanna think about getting a little better set up prior to pulling any big long grades with that fifth wheel you're talking about. highest mine gets since i dont tow anything heavy is about 1450 or 1500 but thats at just over 110mph. I always wondered before i got gauges and to my supprise the hottest it runs is lugging it up the mountain in od unloaded behind some compact doin 55 mph! I constantly have to take it out of od to keep it from hitting 1300. Guess i could detune it... nah!
yea sorry about whole DPF thing i was thinking one thing and typing another. All i can say is there is a reason why the bells go off probly because it not good on stuff to keep pushin it. I do think you need to add more air or turn fuel down. I have 2 of these trucks and i have never seen them over 1200 except one time on the 5.9 i had set on high performance and it hit 1300 but i back out and turned programer down with out serious turbo and air to air upgrades. I just could not justifie that kind of money when it gets the job done the way it is.
1350 is very common with stock 06's on this site with the probe pre-turbo. People even run them for extended times from threads here. Checking or changing air filter never hurts and confirming you have proper boost , (around 30+ loaded hard) would be prudent.
The bells on the Edge are factory set at 212f'. I'm pretty confident that is because water boils at 212f' and it's default the same for all applications. Lot's of guy's who tow heavy run for hours at close to 220 and have very high mile trucks. You can set your alarm and de-fuel point to whatever you want on the edge.
Search around on towing heavy and You'll be much more comfortable.
I read some place where cummins did a bench test and ran a 5.9 SUSTAINED at 1400 degrees for quite a period of time with no problems. My stock 5.9 2007 will see 1300 real easy on a climb pulling my horse trailer. I shift down into 5th and it stays at 1200-1250 with all the power in the world. My probe is drilled into the exhaust manifold right in the middle.
Can someone help me please. I have an 02 Cummins 5.9 with a quadzilla adrenaline programmer. My truck has a smoke switch. It's also about time for an oil change. Saturday I was messing around and one of my buddies wanted to race. When he got behind me I rolled some coal on him using the switch. I turned it off and then when we got to our racing spot we raced and my EGT got up to 1032 after a couple 0-70 races and I got a warning on my programmer. Ive seen my egt around 1000 before but rarely. Now for some reason my truck will climb to 1000 easily and 1100 on some throttle and 1250 if I really punch it hard. I rarely race my truck or use the smoke switch. I baby my truck. But now I am worried to even climb a big hill or pull anything. I don't have my programmer set real high or anything. My power level usually stays on 2 to get better mileage. That's what it was on when I raced also. Does anyone know why it could all the sudden have started getting hot easily? Could it have to do with my programmer/race/fuel/oil/coolant/smoke switch?
Ps. I'm pretty sure my EGT is sensed before it goes into my turbo
Stock (no programmer): 1425*F+ sustained. Think about how many stock fleet trucks are out there with no gauges, driver doesn't have the ability to monitor temps. If it was a concern, EGT gauges would have come from the factory.
Modified trucks are a different story, more energy is expelled in the combustion chamber (more heat), with less heat expelled in the exhaust gasses. This is why the max EGT with a programmer: 1325*F max sustained.
I have seen 1300-1400* sustained on long hill climbs unloaded on my 04.5 with stock injectors and programming in 6th gear. Last July I put BBI injectors and a Smarty JR-06 on it and the temps are still about the same. I pull a 30' fifth wheel often and in 6th gear I can reach 1400*. When I do get to that temp on the egt guage I downshift to 5th and it will cool off. So far the truck has given me 225,000 trouble free miles.
i have a 07 5.9 and do a lot of towing of 12k lbs or more just depends. i drive the I5 grape vine in California and will hold 1400-1500f egts and nothing over 205f water temp. the entire clime and have never had a issue with the truck and i have 180k mi. on the truck now and i do this drive 3 times a week. the compression on the truck hasn't changed. it kinda more important to keep an eye on water temp u really dont wanna see it over 220 for too long before u start to warp things.i also have a edge tuner they do have a flat factory setting for there alerts they are not truck specific. i have talked to edge myself to make sure that was the case. i had to rest all my alerts and industrial injection said to set it about 1450 for stock turbos and 1550 for a phatshaft turbo. set your water temp at 215 alert.
Take care of ur Ram & it will take care of you.
Edge is known to run hotter, Smarty has safer tuning. Tuning w/more hp & advanced timing & your max egts need to come down. Stock these trucks had delayed timing for emissions so egts showed higher [more heat in the exh]
My 5.9 sees consistent, steady, 1400 degree EGT's when I'm truckin' up the entrance into the Rocky Mountains on a daily basis, (pre-turbo) with the probe installed the RIGHT way (probe in center of the rear exhaust manifold port (for cylinders 4-6) with virtually no increase in engine temperature...

Hey guys, sorry for bringing up an old thread. But I just wanted to tell everyone thank you for easing my mind. If you look around on all kinds of forums, many of them say that you cant go above 1200 or so. Are these guys pulling like we are? Must not be, because I see mine above that fairly often. It has touched 1500 and 220 a few times while pulling through the Rockies, and I go very light on the programming. Most threads had me kind of worried, but I see that you guys are seeing about the same results as I am.
Thanks again.
