Pyrometer install - threaded bung or calmp style?
 

I am thinking about installling a pyrometer in my 6.0L and see that there are two different ways to mount the senor tip into the ex. manifold.
My question is, which one is the best way to go? With the threaded bung mount or the hose clamp style?
Thanks for any input.

I put mine in my exhaust manifold. Drilled and tapped.

Mine is also drilled and tapped

X3. IIRC drilled and tapped is the better way to do it, although it will suck drilling and tapping it. Mine is also in the drivers side manifold.

I've had both styes on my vehicles, and i would say drilling and tapping is definitely a more secure and long lasting install (more professional looking also), and since you have to drill a hole for either style, tapping it isn't too much more to do. Less chance of an exhaust leak past the probe as well. I believe the hose clamp style is designed more for installation into round steel pipe, not as much our ovalish cast mani's. (Unless you're planning on installing the probe post turbo, which isn't recommended, less accurate reading.) Good luck! :)

Thanks for all of your replies. You have confirmed my original thoughts. The clamp style just did not seem as good.
Thanks again to all who repied.

When you drill and tap, put a good size gob of grease on the drill bit and the tap. It will collect much of the metal shavings keeping them out of your exhaust and turbo.

Back in 04' this was big topic and it can be researched on this site. I have installed both and use a Bully Bog Monitor to watch them along with boost and volts. I drilled the left side manifold with a glob of grease as stated. After drilling I bent a small diameter weld rod put on another glob of grease and circled it around the hole and picked up a few more chips. A paper clip could do the same thing. I carfully taped the hole with the proper pipe tap also with grease on it. I went in slowly and continously checked the threads with the fitting so I would not tap it to deep. It has worked fine for 5 years. I drilled a hole in the exhaust pipe just behind the turbo for the second egt using a angle attachment from Harbor Freight to make the job easier.
Good Luck
