Just a SWAG so feel free to shoot me down or shoot me at dawn.
Run 2 probes and 1 gauge. Hook it up to a switch so you can flip it one way and the input from the sensor in the pre turbo powers the gauge and you get a reading, switch it the other way and you get post turbo. Why you need both, I don't know but if someone must, that might be a way to accomplish it.

They make switches for type K thermocouples. Also if you just want to experiment there are lots of options for devices to read temps from a type K thermocouple that are reasonably priced. Check around on Ebay for instance.

Isspro makes dual pyro gauges. If you look at their catalog, its on page #4 and the gauge number is R612. Here's the link to the PDF version of the catalog http://www.isspro.com/catalog/ISSPRO...log%202006.pdf

Clay, can you get the R612 gauge and whatever else I need to put that inside your F650 dash? Unless someone talks me out of it....I plan to put a thermocouple on each manifold and monitor the temps that way.

I can get you anything you want man, but I am with Joe on this one. Unless you are dying to see the difference I wouldn't bother with it. Plus they max out at 1200*F. If you really want to see I would get the Performax and 2 pyro probes, that way when you get bored with it you can pop in another gauge and go back and forth if you choose.

International... Ya know the guys who built our motor...
1250* red line. You can tow all day at 1200 and not hurt a thing, but over that and your on your own...
Keep in mind when your looking at EGT's that it is an air temp measurement, not a metal temp. You have boundary air around the piston that is cooler, you have oil cooling jets spraying the bottom of the piston with cool (relatively) oil...
There is some fudge factor in there to play with. If your towing and at 600* and someone wants to play king of the hill, you have alot more time over the red line before bad things happen then if you were towing at 1100* for hours...
Understand?
Add to this...
I have both a right and left pyro, and can see as much as 100* difference at times. This could be due to probe placement and depth, air flow differences in the manifold or up pipe restrictions, lower compression cylinders...
So much to think about... Use some common sense and have fun...

No problem... The Dodge boys use 1350 for some reason, and they have more piston issues then we do!
