The metal shavings you hear about, here's what I did. I just started out drilling the hole with a small bit, then slowly using a bigger and bigger bit until the hole is big enough. Work your way up, start small and just go to the next size, then next size, ect. Some may tell you differently but this is a popular method.

You'll still get some metal shavings, but by starting small drill bit, then gradually getting bigger your decreasing the size of the shavings. I put mine in the drivers side manifold. I've even heard of some people stickin a vacuum up to the hole to try to get some of the shavings out.

It is for you to watch your engine's Exhaust Gas Temperature (EGT's)
So you don't damage the engine.

This is a clamp style pyro. It's used for those people that don't have a pipe tap or don't know how.

If I could piggyback on this thread....
I am about to install gauges and went to buy a tap/die set from the hardware store. The instructions I see talk about a 1/8" NPT tap, but all they have are metric and SAE. How does NPT fit into this?
Thanks in advance!

npt is national pipe thread, most of the basic metric/standard kits also have the 1/8 npt tap as well, if not they are readily available at parts stores such as hom depot and lowes.
i use the clamp style electrode on powerstrokes, its quick and easy, either way you use you wont have to worry about the metal, you are drilling almost straight up. almost all of the shavings are falling on you anyway. the little bit that may make its way into the pipe wont matter. as soon as you crankl those little bits will be well past your blades and out the pipe before the fins start cranking any rpm. i cant count how many gauges i have installed and i have yet to damage a turbo

Not to be too picky, .....But
NTP is National Pipe Taper, as compaired to NPS which is National Pipe Straight. Both are thread forms, straight being just that straight, while taper is tappered 3/4" per foot. Straight pipe threads are used to make mechnical connections, and tapped pipe threads are used to make water/gas thight connections.

And always remember that they are tapered! The top of the tap is lager in diameter than the tip so the deeper you tap the bigger the hole you are tapping into will become.
And it is possible to tap too deep and wind up with a situation where you will not be able to tighten whatever it is you are putting in there. SO BE CAREFUL whenever using a NPT tap. O yea, and as far as metal chips go. I would not be to worried about it any that that get left behind will just get blown out the exhaust or completely incinerated by the heat of the engine.
