Iíve done it on a truck motor
and of course many airplanes.
Bu those donít have water
Seeing as how you have a turbo, TIT or turbine inlet temperature or the PC TGT for turbine gas temperature is likely better and easier to accomplish.
On the truck it was drill a 1/8Ē hole and tap it for 1/8Ē NPT, measure depth
, adjust the thermocouple for half that distance and install.
Aircraft it was drill a hole in each exhaust tube approx 2Ē from the head
and install thermocouple, they were held in place by hose clamps.
My guess is that your dry exhaust is most accessible just before the turbo.
What I found was a performance Diesel
usually didnít exceed 1100 F very easily in stock trim and I limited mine to 1400 max. Aluminum
melts at about 1200 F I think, but piston temp is nowhere near as high as exhaust temp.
Gas motors, aircraft anyway regularly ran about 1400 ish if memory serves. I ran my Lycoming 50f rich of peak, and a Continental 100f rich of peak.
will idle at very low temps, less than 200f and a gas motor
much higher. If I remember right I think my Duramax would idle about 150f.
An issue your going to have is what temp is high enough?
Duramax if an remember right ran down the road at 600 to 700 ?
All numbers in Fahrenheit.
