85844, EGT Probe Placement Idea
Posted by extreme97nt, Feb-10-05 10:25 AM
How accurate would it be to mount the egt probe in the hole in the head for the EGR tube? I was going to tap and plug it but I am thinking about mounting my egt probe in there. Any thoughts?

I think you need to get a meter that reads over 1600^ Let us know. After looking at the head I'm working on, I don't see why it wouldn't work. As for what readings you'll see, I don't know.

If the temp is over 1600* wouldent shit start melting?

Does that hole have access to all the exhaust ports or only #4?

It only goes into #4. However, The rule of thumb is to place it infront of #4 because that gets the hottest for some reason. I just think it would be a cleaner install.

the only thing i would wonder about is if it would get enough flow past it. since in the exhaust manifold the exhaust is carried directly over the sensor head, whereas the egr valve hole is offset out of the direct path of the exhaust.

Very good point.

Well I got ti mounted and 1/4 of an inch of the probe is in the exhaust flow. SO we will see how it works. If not I iwll jus tplug it up and put it in the manafold again.

interesting... i'd think you'd read hotter cause its closer to the head...

Let us know dude. I'm finishing a head now and would like to try this if it works out for you. That way I can use my currect location for the wideband probe.

It will probably be a while I still have quite a way to go. I will post the results when it is fired up though.
