EGT Probe Location Idea

I know most guy puts the EGT probe in the end of the exhaust manifold. But i was wondering how much different would it be if you drilled and tapped the collector pipe that feeds the turbo. I would think it would get more of accurate reading from a mix of both sides of the engine.

Then again it could be a terrible idea but i wanted to throw the idea out there at least for discussion

Drivers side is the hottest side, that's why they recommend it there.

It would be better than then down pipe and it should give you a more accurate number of what the turbo is seeing.

Why is it that the Drivers side runs the hottest?

I believe peeps install it in the driver side manifold because it is a whole lot easier to get to.

^That would be my thoughts on it. Close to the turbo on the hot side is as accurate as you can get - whether or not you can get in there to drill is beyond me - I don't have an EGT gauge on my truck, but then again I don't push the hell out of it ever, either.

And by "hot side" I mean hot side of the turbo, not hot side of the engine (left vs. right)

I don't think anybody is worried about the heat the turbo is seeing. The idea is to catch it at its hottest point so you can tell what's going on. I think the problem is that you start heating up the valves and seats.

Ideally then you'd want one on both sides near the runner of each cylinder (like some of do with our drag cars). I was just thinking to get the accurate average of whats going on that'd be one of the best places to do it. I can't imagine that it cools down too terribly much by the time the exhaust gasses hit the turbo...

Don't know. All I know is I have dual pyros and the drivers side reads 50 cooler than the passenger side. My 95 was the same way. Maybe I'm completely wrong but that has been my experience on 2 trucks.
