Thanks for all the ideas and feedback guys, I was thiking of running a turbo on my truck. And since I'm a welder and I work in a machine shop I could have the exhaust done in a little while, I was even thinking of just running some tacks through the bed but I haven't decided yet

That knob looks bad ass! But I was thinking of machining one out of aluminum or stainless, and just for kicks an giggles I was thinking of making a custom pistol grip shifter like the old school mopar hemis came with

Water temp, Oil presure, and EGT. These are the father, son, and holly ghost trinity of life for your motor. I wouldn't want to see an IDI on the road without these.

Sorry to bring up an old thread....

I'm going to try and put in a triple gauge pod in my 86'....will be doing the pyro and water temp. Was looking for suggestions on oil pressure vs trans temp (I've got the C6).

Thanks in advanced

Are you planning on a lot of towing? I've always heard the C6 generates lots of heat.

You could always put one more gauge somewhere else and have all four.

Not planning on much towing at all. Mainly used as a hunting truck. I might tow my Isuzu Trooper twice a year (if it ran and if I had a trailer).

Thinking I’ll just go with oil pressure for now and add the trans temp later if I fell the need.

Thanks!

That's what I would do if you're not planning on lots of towing.

I have oil pressure and water temp on the bottom. Boost, egt, and fuel psi on the pillar. I would not like to drive something and not know the oil psi. The stock gauges suck

Thanks for the pic! That looks awesome...definitely jealous of your third pedal

Since we're talking gauges, why are the pyrometers SOO expensive? Like, $200 vs $20 for all the others? Is it that much more complex?

Also, I think I know the answer, but are they just as important on NA as they are with a turbo?

According to a few guys on here they're actually MORE important on an NA truck because they don't have a turbo to add extra air in the event they're over-fueling.

Can't answer why they're so much more, probably just economics. There's a greater demand for oil/water gages, and therefore they're producing more and able to sell them cheaper? Really just a guess, really don't know.

Heat measuring will always be expensive. Design and material comes in to play a lot. Usually they are thermcouples (more stout than an RTD) as they withstand higher temps and can last longer and respond quicker. Best I can explain is a thermocouple creates voltage to be measured, and an RTD(resistance temperature detector) uses resistance.

To add, most pressure gauges are just a coil, spring, or diaphragm. Price difference on larger equipment is like $120 for a nice 4” pressure gauge vs $700 or more for heat stuff. Thermocouples and rtds need extra material (thermowell) to protect the wires too.

Anyone found a good TypeK thermocouple for measuring EGT?

From what I can tell, electrically, all Type K thermocouples are compatible. But mechanically, they come in many configurations for specific applications.

Note many Fluke DMMs have type K thermocouple inputs as well. It should make a good reference for calibration.

Thermocouples work on the Seebeck effect of temperature differentials across junctions of dissimilar metals. It should be accurate as long as it is intact.

One thing about thermocouples...only use type K thermocouple wire to extend type K sensors, otherwise, you will make unwanted thermocouples. Chromel wire to chromel wire, alumel to alumel wire. All the way to the terminals at the gauge, where the gauge knows the temperature at the gauge. Not doing this will likely result in incorrect readings, which will not be appreciated. If you don't know about this, do a little research until you see how the magic trick works. Few things are worse than trusting a lie.
