ETG moved it.

[Trailer Trash 2]

Well I had my ETG moved from after the turbo, to end of the header and the beginning of the exost tube up to the turbo driver side.
I can say one thing when you hit the peddle hard the temperature sure goes up fast, compaired to where it was after the turbo where Banks installed it the first time, I had a diesel shop install it for me $135.00 I think it was a reasonable price. now I have to get the fluids changed in the trans before we go to Hagermans RV Village in Idaho this September.

Does that mean "pre turbo" which is were mine is. Sure does get hot in there doesn't it.

Mine is in the left exhaust manifold. It goes up fast when you stomp on it.

Everyone I talk to recommend pre-turbo, Rich. That's where it's the hottest.

I have yet to install my gauges yet so I'm throwing this out there, pre-turbo seems to be the correct choice and from what I've read 1100 is the norm and 1250 would be the max and damage occurs between 1300/1400. Can stock TV's hit these temps while towing or is this a chip thing? Also are pyro temps engine specific as to max temp specs. and are the numbers/assumtions I've stated above even correct? Steve

On my 08 F-350 Ford 6.4L My guage is set to give me a set of red lights at 1200 degrees. We stay below that parameter. When the red lights come on we back off.I can see the temp and the lights. We have plenty of power left and could go much faster but we fly by the instruments. Is anyone surprised that I stay within specifications and manufacturers parameters. I would check with the truck manufacturers for the proper spec's. Under average driving conditions trowing we are at 600 to 900 degrees at 60/63 MPH. We did pull some over 1200 on I 80 East in PA yesterday.

Steve: Per Cummins 1250° All day long
1350° 1 Minute
1400°+ 10 Seconds

"The Pyrometer is the most important gauge a turbocharged diesel engine can have. Pyrometer readings allow the operator to constantly monitor the engines "safe zone" of operation. The exhaust temperatures are monitored with a probe inserted into the exhaust flow. The probe can be mounted pre-turbo or post-turbo. PDR strongly recommends all probe tips be installed pre-turbo. Pre-turbo temperatures of 300° F to 1200° F will be normal working levels. Temperatures above these levels can only be reached for very short times ( 10 - 20 seconds ) or engine damage can result. "........... As a guide line.. Engine spec's will differ some....but not much..

Rich, so the way I was reading my post turbo and never exceeding 1050-1100 those temps before.
Now with the probe at Pre turbo I will be safe to reach temperatures readings up to 1200 not to exceed 12-20 sec.
Does the temp go down when I pull a hill, let say I'm pulling in 3rd and get close to temp if I down shift and take some of the strane off the pull does the temp still go down, as before I moved the probe.
In other words do I still drive the same as before? the only thing that has changed is I'm getting a true reading on the temperature.

The difference between pre and post EGT temps can be 200/300 degrees with the pre turbo being the hotter.That is why it is recommended to be pre turbo.1000 degrees post turbo can be 1200/1300 pre turbo. In my experience..If we are running on a good pull at 60 MPH and my warning light goes on at 1200 degrees I have to back off, slow down, reduce boost..It may be only 5 MPH to keep it below 1200 degrees but we have been as slow as 45 MPH on some real good grades. Ole Rich could show off and pass those big gassers alright.....but the instruments do not lie and this buggy cost me a bunch of dollars. We are IFR all the way.

Mine is pre turbo also, I want to know what the temp is before the turbo. On another note the tops of the pistons are aluminum and will melt if sustained temps are 1300 degrees or more.
