PRE-TURBO EGT w/o EGR DELETE

[YTEP_F450]

Alright so haven't received any response on where to stick a pyrometer if you don't want to delete the EGR and cooler. So I took H&S pyrometer location and adapted it to my stock system. I tapped the EGR intake as close to where it attaches to the manifold as possible. I've attached pics to help. I also spoke with my local dealer service manager regarding if he thought a pyrometer located on the EGR intake was a good idea. He really couldn't think of any reason why not. My only concern was that the exhaust flow might not be sufficient enough when the EGR was closed to provide accurate exhaust temps. He informed me that the EGR is open a majority of the time and I should be getting fairly accurate readings.

So the pyrometer has been in for about a week now. I've got an Edge Insight displaying both readings from the newly installed pyro and from the stock EGT sensors. The new pyro while towing is approximately 400-500 degrees hotter than the stock post-turbo sensors. The highest temps I've seen so far have been going up a pretty steep hill, towing about 7000 lbs, at 55mph. The EGT read at 1325 pre-turbo and about 800ish post-turbo.

I'll keep posting as I use the new sensor more. Has anyone heard what the max pre-turbo EGT should be? I know on the older pstroke max was 1250, hopefully the 6.7 is a little higher.

1325 degrees is too hot for any turbo IMO

I thought so too, especially for a bone stock truck, not running any tunes. I sometimes haul up to 18000 lbs with this truck, I haven't yet seen what the EGTs are when I have that much weight behind me. Hopefully they don't get much higher.

It is probably well above that when it goes into regen for 10 minutes at a time.

True. I think the problems with turbo failure start to occur when you have extended periods of high EGTs. I'd imagine that the high EGTs during regen probably decrease fairly rapidly once the regen cycle is complete... assuming that your not pushing the truck real hard.
