you sir are correct!

 

WHat readings do you see typically when tapped on the test pipe with TT? Under normal driving? Under WOT?

 

If installed on the pipe reading should not exceed 1380F
If installed on the manifold 1550F

I realize all of the "JDM" gauges read in C. That translation is 749C on pipe, and 843C on the manifold.

 

^^Should not be below or higher than 1380f??

 

Should not be higher than those temps. Investing in a Peak/Hold style gauge with a warning LED is money well spent in my opinion. Set the warning LED to flash well before those posted temps, to give yourself a lil time to back it down. Also consider that there will be a little lag between what your EGT's actually are, and how long it will take the gauge to tell you so. If you are consistantly climbing temps at a rapid rate, it's time for a retune. Either too much boost or timing without enough fuel to back it up is the culprit most of the time.

 

Cruising at 60mph I hit 900f.....cruising at 80-85 just a hair over 1100f...not sure about WOT. Defi gauge

 

You guys are awesome! Thought this was a dumb question at first cuz i found nothing searches. I have the defi VSDX and all I need to get is the sensor and also need to see how I will do this with my powerlab kit.

 

^^ Thats about what I get, mine is 100f higher but could be due to different sensors/gauges/location ect.

 

I have an aps down pipe with an egt bung installed if you need it.

 

The difference in the location of the sensor would cause the difference in the reading only if the two cars were identical, exact same mods, exact same tune, in the exact same atmosphere. The gauge and sensor type are irrelevent as long as both provide an accurate reading.

What DOES make the difference is the set up you guys are running, as well as the tune. A Few degrees timing or an extra pound of boost without sufficient, or even too much fuel will make a drastic difference in EGT temps. Atmosphere also affects EGT readings for obvious reasons.

Both your cruising temps are normal and safe regardless of the 100degree difference. It's how fast they climb and what they climb to at WOT should be the thing to keep an eye on.

 

Thanks for such detailed info. I have had my warning light set at 1300f and never got the flashing light yet.
