EGT probe at the turbo?

This has been bugging me for a while now.

Has anyone put the egt probe right at or in the exhaust inlet of the turbo?
Just wondering if this area would be the best for temp readings? I know, the manifold is the gospel, but could this area be better?

Wouldnt read any different than at the manifold. And would be harder to get to.

Well ok, then what about right at where the DP hooks up? I would assume that area would stay cooler due to having the turbine housing volume diluting the heat load.

I'd think that you'd want to keep the EGT probe on the pressured side of the turbo.

At the moment mines in the downpipe aft the turbo. I'm moving it to the drivers side manifold for more accurate readings when I tear everything down to do the ARP studs and gaskets. Done allot of research, it's also where all the gauge manufacturers suggest as well.

Mine is to. I just keep it less then 800* for extended periods and 1000* if it's a quick hammer down/race. Had no issues thus far

I use to have mine in the down pipe, 4" after the turbo. My EGT's would only reach 1100* @ WOT with a race tune post turbo. Now it's in the manifold and at WOT with a race tune I can get 1500+ EGT.

dee004 sent me this link. He and I had the same discussion. I was ready to mount my EGT sensor in my down pipe til I read this article.

Ford Diesel Power Powerstroke Performance

I am now going to mount it in the drivers side exhaust manifold.

I understand about downstream of the turbine wheel getting cooler readings. the volume of the DP is greater that the up-pipes or manifolds which would make for a greater cooling effect. I was talking about right at the turbine wheel in either spot(inlet or outlet). I would feel that either spot would give the best temp reading at the turbine. I feel the manifold gives a better reading at the exhaust valves, ports, and pistons.

I have a probe in both headers and the passenger side reads around 50* hotter due the longer path compared to the drivers side. Not to mention the bend at the exhaust inlet.
