About the place for the probe, I would rather measure the oil temprature, but I feel that doing so would require a good seal that I couldn't make or feel like buying. Sounds like measuring the exhuast gases will be the easiest option, I think I'll just mount it below the heat shield. Seeing as this is only an expiriment (not anything for tuning the engine), that reading should be fine. My only concerns are that the reading could exceed 300 degrees F, and that the headers might be the hottest place in the engine, giving me an inaccuratly high measurement.
Thanks so much for you help.
I have a feeling I won't be able to find that grommet, knowing my luck, but I'll get back to you.
I don't know if the grommet is in the same place on yours as it was on mine but look around as there are probably several ways to get through.
You definitely won't be able to use that 300 degree thermometer on the exhaust gas measurements as they get as hot as 1500 degrees. Oil temperature wouldn't be too hard if you had the right connecting hardware to tap into the oil pressure sensor behind the engine block. I have my oil feed line and my mechanical oil pressure gauge tapped into the sensor at the moment. You also might be able to get a probe welded into the oil pan and can measure it that way. Water temp isn't hard either.
I am just trying to figure out why you are going through this trouble for just an experiment. If there were a useful cause, it would make sense but I would rather spend my money and time on something that I know is going to do something productive. Just my 2 cents.
Good luck though and if you need any more ideas or tips, let me know.
