I just installed my new gauges and have been watching my egts and they seem to be running too high. The gauge is showing up to 1400 at times on a stock truck with little to no load on it. I wanted to find out what other people are getting on stock trucks with the 6.7

1400 means you are going into regen. it's normal, i still do'nt see how it can be safe, but every 6.7 does it with the dpf still on.

Yep that is a normal regen temp. When my truck was stock I could hit 1500 going up a hill during regen.

I don't have a 6.7, but out of curiosity, are those temps pre or post turbo?

Pre turbo. I am getting the same temps often!! My truck will see 900 deg. just driving down the road in front of my house. These 6.7's run HOT!!!!!

One other thing I noticed was that my truck went into regen and then about 2 minutes after it went out my egt's were through th roof

I wonder what the long term wear is going to be on the turbos running those kinds of temperatures.

My EGT's were like that when my truck was stock. 1300+ when it went into Regen and then 1000-1100 durning driving, and 1200+ while towing. With the mods I have now, I'm around 680 at 70mph, and while towing a 28ft trailer at 11,400lbs I'm around 850-900. I can't even hit 1300 anymore :thumbsup

Gotta get rid of that DPF and that delvish EGR to get the good low EGT temps for the life of your engine. My 02.

Just the electronically operated actuator for the VGT is water cooled, but supposedly the turbine is made of inconel and is super heat resistant.

The 6.7 turbos are water cooled as well as the usual oil lubricated - not sure what that means for long term wear.
only the portion of the electronics are water cooled. None of the Turbo housing is water cooled.

From examining a spare turbo it appears that the water path goes across the housing rather than straight through the electronics so even if the primary purpose of the water is to cool the electronics the housing has water flowing through it from one side to the other so there has to be some cooling benefit to the entire assembly.

Boy I'm glad somebody started this thread, cause I was wondering the same thing. When I installed my Edgew/att. and saw the egt's I got scared. When just running around it was 900-1000 and when in regen it was anywhere from 1100 to 1400. I thought maybe I installed the probe wrong or something. By the way what is the regular Engine temp? Or a good running engine temp. The reason I ask is because occasionally it will hit 210 degrees. And the preset edge alarm goes off.
