I just installed autometer gauges and my egt is about 400 at idle 800-1000 crusing and If i punch it, i can get it up to 1400. This is all on stock power, I have a Triple Dog but I am on stock power settings. I have read that you shouldnt run at 1200 for an extended period of time, but with me running at 1000 just cruising, i think that if I add any sort of a load I am going to be 1200 easy, I also live in the rocky mountains so everything I pull is either up or down.

Are the EGT reading ok for what I am doing and what happens when I turn on performance and carzy larry. I am sure there is going to be a bit more then 1400. Please let me know

thanks

I forgot to say that this is mounted so it is more of a preturbine inlet temp, The probe is by the flange of the turbo and exhaust manifold

I drove my 05 for two and a half years without gauges and about a month ago I finallly put the gauges on and was SHOCKED. Running empty and getting on the pedal pretty hard I can hit 1450 going up a freeway ramp and this is completely stock! I have put 60,000 miles on it so far and a lot of those miles were dragging some pretty big loads. So far I have not noticed any signs of damage, so maybe they can run that hot? Bout a month ago I put a Smarty on and that brought the egt"s down quite a bit.

 

I just installed the Auto meters into my 07 5.9 SAME readings as you. yes, they are Normal. I believe cummins says our engines were designed for 1350 for 5 minutes constant? Read that some place. But yes, those numbers are normal for these trucks!

 

These Cummins seem to run pretty hot, your numbers are close to what I seem. Most think they run so hot because of the extra injection event. I still try to keep my temps below 1250, but I think these trucks are capable of handling temps up to 1400.

 

what's your altitude? the higher you go, the more throttle it's going to take to get the same power you would get at lower altitudes, therefore higher egt's.

 

I wouldn't be overly concerned with short bursts, my understanding is that 1400 is not a problem. I would only worry if you kept it pegged for miles. Just think about how many trucks are out there with no gauges.

 

Altitude, thanks for that input. never considered that! I live at near sea level! Have traveled to 3-5,000 ft and see similar so wonder how high you need to get to really see a difference!

 

I did not have gauges before the Smarty Jr. (got them both at the same time), but with the Smarty Jr. on level 2 – towing, and a 10,000lb 5er, when I have to floor in getting on the highway from camping in the high desert @ 3,000ft elevation, I am usually only at 1,285 - 1,300 max (for a short time – until up to speed). My probe is pre turbo in the manifold. Normal driving with normal acceleration, I range from 400 – 850 +/- depending on acceleration and coasting. I heard the Jr. keep the EGTs lower. Might be a consideration to get.

 

my alt is right around 6500 but I am 15 miles away from 10500 and go there all the time. Can anyone tell me a temp that should a max? This is what I am looking for

thanks

my 07 was seeing 1500 climbing with a trailer

 

I've heard some people say that 1400 is real high, and others that aren't worried untill they get to 1600 or so. I think that what matters the most is just not staying in it for very long at those temps. As for my truck, I can hit 1450 easy in just like 0-60.
By the way, Nathan, I live in Norwood and I'd like to see your truck some time.

 

Such a big differance in models/years. Pulling 8k plus max egt for me is about 1150 and you gotta work it to get that.It takes a LOT for me to hit 1200 towing.

 

the 04.5 up were designed to run hotter, get a smarty Jr and get the software for the 04.5 up for the smoke , this will lower your egt by about 200* . there is more things you can do to lower the egt even more but starts getting expensive one good thing about it the mpg goes up with each one
