can someone take a picture for me of where they installed their egt probe. only want pictures of before turbo. it would be nice please, cause i dont wanna drill into something and have it not work out for me. thanks

 

Hope this helps.

 

thank you so much

 

dean, there is a center divider in the manifold so DO NOT try to install it in the center! i was told that the read 3 cylinders run hotter so i installed mine on the back half where as Luke has tapped the front 3. I have no proof to actual back up which run hotter, but that's what i was told

 

Here are the complete instructions.

this may sound like a dumb question....but....can the pyro be installed after the turbo or no? i just didnt want to have to uninstall the turbo as to get the metal shavings out from the drillbit. if one can be installed after the turbo what kind of temps would one be looking to have? and if before the turbo?

The temps would be off by about 400 degs. if you go after turbo.

 

you do not have to remove the turbo i just did mine, i greased the bit and when i drilled it pull the fillings out then after i was done all the drilling i vacummed out the shavings and you can use a magnet also, then install the probe to the back side of the manifold where it goes to the turbo, because then you get the back side heat and there the warmest, the front dont matter as much, then turn truck on and let it run for a few minutes before revving it so the exhaust can get ride of any little fillings and it will not damage the turbo at all, the guy who told me this has done many of these. it turned out perfect and hadent had a problem with any of it. good luck.

 

I greased the drill bit & when I got close to going through I started the truck and let the exhaust blow the shavings out.

 

I've always greased my bit and tap, and cleaned/ regreased often. No problems with 3 or 4 trucks. The manifold is incredibly soft. I cant believe they last as long as they do.

The difference between pre and post turbo will vary with the amount of fuelling and whether you are in or out of your turbo's efficiency map. I have seen 450+ deg difference.

POST-turbo probes are merely an un-educated guess to what is actually going on.

There are too many variables between applications to set a reliable base-line of just what is too hot from one truck to another.

Pre-turbo temps are pretty standard and reliable.

Drill the hole centered in the rear half of the manifold exit, as there is a solid divider in the center.

Also, DO NOT run the tap too deep; as, the probe threads are tapered NPT.

Run the tap too deep and the probe will never tighten.

 

ok thanks for all the info. i will go pre-turbo. what kind of temps should i be aiming for stock? and then what is safe? for when i turn the pump up?

 

12 on the pyro is about the max you should let it go

 

ok thanks!

 

What kindof grease do you recommend? I got some axle grease lying around would that work.
