Pyro install question

[BioStroker]

Where is the correct place to install the thermocouple for a pyro gauge? Can it be installed after the turbo on the exhaust down pipe?

bump on this one...anybody?

Drivers side exhaust manifold

The pyro on my truck is installed on the exhaust downpipe. I'm looking to upgrade to a 4" turbo back, and the thermocouple is welded in. Do you think I can salvage and re-use it? I'll install it in the correct place this time!
Anybody have some pictures? Is it hard to drill and tap the exhaust manifold?

You should be able to re-use it easily... there is probably a fitting that is threaded into the down pipe that the thermocouple threads into. Remove the thermocouple, remove the fitting, then just drill and tap your manifold or up-pipe. Have you ever used a tap before? It's pretty straightforward, but the two things you need to know are that if the tap is off center in the hole very much it may break off (and they can be a biotch to get out if that happens) and when you are tapping, go in 1 turn then back out 1/2 turn to break the shavings loose so they don't plug the threads on the tap and make it bind or break. Use some sort of cutting fluid, a little bit of motor oil would be fine for this application. Drill your hole pointing straight down, and 95% of the shavings will fall to the ground when you drill and tap... there is no sense in worrying about anything that might be left inside once you are done. Some people like to grease the tap to catch the shavings, I don't think it's necessary or a good idea.

drivers side manifold, easiest to do it from under the truck, make sure you put it in a spot that you can use the tap handle and not hit anything

Thanks for the posts. Does anybody have a picture so I can have a better idea of what I'm getting into? I've tapped skis before when I was a ski tech, but nothing metal. Is there anything in the manifold to accidentally drill into?
