Best placment of EGT probe

[Im_Strokin_ur_Cummins]

Ok so I got a set of gauges today for christmas (yay finaly lol) but anyway I been going back and forth with my father about where the probe should be put. He says every time he worked on a turbo, the probe was put after the turbo not in the manifold. However I been reading on here the best place for the probe and that is at the end of the manifold driver side. The old man keeps saying that it doesnt make since to put it there since the idea of it is to see the temp of your turbo so you dont cook it. So I want to know from people on here what they think is better either post turbo or on the manifold

You don't wanna cook the turbo, so put it before. You put it after, you'll have that exhaust gas cooling off so you won't see what's going into the turbo.
But you don't wanna melt your pistons either, do you? In the manifold allows you to see what's coming out of them and then as long as they don't get too hot, the turbo won't either cause by the time it gets to the exhaust housing, it's cooled enough to be safe. Manifold vs. DP temps can be 600+*F off.

Pre-turbo. Driver's side manifold

As stated, the driver side manifold is the easiest spot to run it and the best as well. This little write up on Diesel Manor really helped me know what I was looking for when I installed mine!

hope that helps you out!

Your not watching EGT's to protect the turbo... The entire truck could melt down and the turbo would sit there making boost happly...

Watch this video...

Now go out and install your pyro probe PRE TURBO to protect your aluminum pistons...

ok I got it aluminum pistons dont work lol. And I plan on putting it in the manifold it just a matter of convincing the old man that is were it goes

Pre-turbo will be much more accurate than post, and you have to have a probe/gauge designed specifically for post-turbo placement if that's what you're looking to do. They are calibrated differently. I believe the post-turbo setup is "fudged" to approximate what the temp is like before the turbo even though it isn't reading from that point.
