Pyrometer

[glennpagano444]

Thinking about installing a pyrometer from autogauge, but I am questioning myself. I dont want to run into any problems installing it or in the future. I have a couple of questions:
1) When installing it I am using a R drill bit with a 1/8 npt tap is this right?

2) how dangerous is installing it in the exhaust manifold, with all of the little bits of metal going into the turbo? Many people are telling me this is a bad idea.

3) Did anyone have any problems installing there pyro and ruining there turbo?

4) Will this meter affect my warnty?

5) Is there anything else I should know about?

1.) R drill bit and 1/8NPT tap is correct
2.) If you take your precautions, not very. Take your time, no need to rush. DONT grease your drillbits and DONT do it with the truck running are my personal recommendations, some people believe otherwise, but to each his own. Greasing the bits can make the shavings hard to clean out afterwards, and leaving the truck running you have the chance at pulling one through the motor to the turbo.
3.) see above ^
4.) Unless you make a mistake somehow, I dont see how this could affect your warranty, but im not experience with that area so maybe someone else could answer better.
5.) Wear safety glasses! Most of the shavings will fall in your face. To clean up, I used a small vac my dad had brought home that he uses to clean out small computer parts, and taped a flexible straw to the end so that i could get it to either side of the hole. 10k miles down the road, i have not run into any issues.
Good luck with the install

Thanks for that info! Does anyone else have any input?

+1 , I agree with what bigwhite said. Take your time and go slow, important thing here is to not snap off a bit in the manifold, or drop it into the manifold. Put a small magnet on the drill bit to magnetize it and it will collect the shavings, then stop periodically to clean the bit off. It's not too bad if you just take your time. Good luck Bro!

P.S. - its a lot worse to sit and think about what could go wrong than actually going out and doing it. i debated for 3 weeks before i did mine, but i got sick of looking at the gauges in the box, and after talking with a buddy who is a machinist, he convinced me that i was worrying about nothing. 30 mins later, i realized he was right.
remember the basics, and youll be good to go

+2 for not thinking about it, I did my gauges with a broken finger and it was the day after christmas, cold and everything. I dont think I even thought about it. I love my gauges, enjoy them and just do it!

I haven't done it myself yet, but I will soon. I asked my cousin about it and he told me not to put it in the manifold. He said put it behind the turbo in the downpipe and add 400 degrees to the EGT and that's what it most likely would be before the turbo. He's been a diesel mechanic on big trucks for 12 years and he's said there's been at least 5 occasions where the end of that pyrometer has burnt off and gone through the turbo. Obviously the turbos were wasted in every occasion. It likely won't happen to me or you, but times are tough and I don't want to take the chance of having to spend a whole lot of money on a turbo.
