I am getting everything prepared to install my turbo that has been patently waiting in my garage all winter. I want to make sure I get as much done before the actual install as I can so that it goes smoother.

I got an EGT gauge to help monitor my engine. Where is the best place to mount the temperature probe? I have a log style manifold and am wondering if the probe should be placed in front of a certain cylinder, right before the turbo, or somewhere else for the most accurate reading. Any suggestions?

 

Right before the turbo. That is where mine is. PM me if you want me to send you a picture.

 

Place the pyrometer in the manifold collector making sure that you leave enough slack to run the wire to the gauge. Also, make sure that the wire is safely out of the way and not rubbing on any moving parts.

 

Ok, I was planning on putting it right before the collector, but wasn't sure. Thanks guys.

 

Also, just an FYI. Unless it's a really beefy EGT probe, it's not a good idea to leave it in the car at all times. When it goes through severe heating/cooling cycles the probe end will become brittle, and eventually crack off and shoot into the turbo. We all know what the end result there is.

For those that don't believe it happens, I've seen it happen twice.

 

I have an autometer NG EGT gauge and it's been in for a year with no problems (so far). Also when you drill the hole in the manifold leave the car running at idle and the shavings will blow out the hole and not into your turbo.

 

Granted it's not going to happen instantaneously ;) It varies widely upon the materials and thickness of the EGT probe. It happened to one of our Grand-Am Koni Challenge cars when we were tuning it on the dyno, the EGT probe had only been slightly used (only around fifty dyno pulls).

 

i had an egt probe in my dsm for years and never had a problem.. and my wife has had an egt probe in her greddy manifold on her tc for about a year now with no problems.
