I want to thank all of you that sent me help on installing my boost gauge. It is in and working fine. I put a "T" into the MAP line as close down as I could and I get very little bounce of the needle. I have also installed a trans temp gauge. Now I am ready to try a pyrometer as I mainly use the truck to pull a 5th wheel camper and I understand it is very important to keep tabs on the turbo temp. My question is where does the line go in at and do I need a electric one? Also, how hard are they to install? Thanks, Mike

 

Drill a hole into the exhaust manifold down near where the up pipes bolt to the manifold. I can't remember the drill size but then you tap the hole for a 1/8 npt. If you research it you might find a picture of where exactly to put it. Also check the stickies for a 'how to'.

I have used a 21/64 bit, 11/32 is a bit too sloppy for me. I have used a 5/16 in a pinch but its pretty darn tight and I would not suggest it.

I'm pretty sure most generic parts stores(Oreilly, autozone, NAPA, etc) even carry the taps up to 3/8s NPT, as well as the associated drill bits needed for the job.

 

when you buy the pyrometer the directions should tell you what drill bit and tap to use.

 

Clay even sells the drill bit and tap.

 

her eis a tip. Drill and tap the hole with the engine running at an idle. that back pressure will blow any shavings back out the hole. Make sure to wear goggles
