Pyrometer question

[ScottnID]

OK, so I'm new to the 7.3 world. I know this thing is measuring heat, but what exactly... exhuast?

How should I be using this guage ~ what's normal?

Did Ford put this in or are these guages strickly aftermarket ~ and does this indicat that the truck was chipped at some time?

Appriciate any help

egt gauges tell you how hot the exhaust is... this tells you if you are running to hot so you can back out of it with out causing damage... as in melting the motor. 1250* or below is the safe limit for any extended periods, anything over that should only be done in SHORT bursts. the gauges are aftermarket only and were not installed factory. the gauge will not tell you if its been chiped or not. it only tells you what the exhaust temps are at that exact moment

with wroitt. You can find the probe tapped into one of two spots. Either its screwed into the exhaust manifold (usually the driver's side) or it's in the down pipe after the turbo. Many people install it in the manifold where it's more accurate.

if its in the down pipe i would highly recommend moving it to the driver side manifold

I'll have to check it out Will...What will I be looking for... I'm imagining a threaded probe with 2-3" inside the pipe and 1-2" sticking out with a wire harness attached...?

Should look something like this....

If it has never been over 650* it is either messed up or in the downpipe
