This is a few pictures of putting in my pyro probe.

This is where I started by grinding a small hole. Then drilled.

I just happen to have the right size tap and die.

I was able to tighten it down no problems.

I realized after I put it in that I have no idea how it should be wired. I know one wire is the positive(the red?) but what I'm wondering is, does it need a 12v source?
How have you guys wired it?Edited by: quantum mechanic

Nice pic.......
But what is it.......lol

Yellow is positive (+), red is negative(-), connect to the appropriate meter terminals - remove the shorting spring from the meter terminals.
Probe generates a small voltage, increasing with heat.
Meter is calibrated to read that voltage in Deg F.
Should show about 300deg at idle.
You will need +12v and common for the light.
There is a small boss on the other side of the exhaust\turbine housing from where your tap is - much more convenient, as tho it was designed to be the factory location.........
Drill and tap it with motor idling - exhaust pressure will blow chips out of hole.

Thanks gmctd, not sure about the boss's location but this is where my drill would fit and pre turbinewheel and pre WG seemed optimal.

I put the Boost tap in the center of the upper plenum, but that really thick ledge on the passenger-side rear of the upper plenum is a good safe spot for the 1/8" npt\1/8" tubing fitting.
Nylon tubing is ok for Boost, but use copper or steel tubing for the Exh Press gage, and the tap needs be pre-turbine, also.
Don't fergit to post results on ur new EGT read.http://www.dieselplace.com/forum/smileys/Approve.gif
On edit -
Second glance at ur pics - show and tell rules!!!! - really need to do something about that turbine bearing oil supply line - kinky ain't cool, here, dude.
Try a little gentle rework to open it back up - save the bearings.

Yea, that doesn't look too good. Mine started to do that so I just quit tightening it. I figured a little oil seepage would be better than no oil to the turbo.

How far is the end of the probe from the turbine wheel? It looks like it would be close.

I could swap it out. I bent it tighting the line down with one wrench instead of two. The turbine wheel is inline with the center section(changed a couple and rebuilt one). I'm inches away. my tap is across from the WG port( Remember that I took this turbo apart because I couldn't spatialy conceive it in my minds'eye. Consider it a test location.
Could you tell I changed the contrast on the pics so you can see what it is.Edited by: quantum mechanic
