Coolant temperature Porsche 991.1 GT3

[stonee]

Hi guys
anyone has the technical information about coolant temperature of a 991.1 GT3?

I found out, that my GT3 show very accurate temperature level in digits and analog. Comparing to my other cars it looks strange. I am used to have cars with temp constantly at 90°C (+1/- 1°)

The GT3 travels quite fast between 80° and 92°. I changed the thermostat, but got a very similair result.

My theorie is now: Common street cars shows an average (of about 1min) of coolant temp, but GT cars show the accurate (withou delay and not an average) of temperature?

Anyone has a GT3 GT3RS and has the same expierience?

Thanks a lot for professional answers.

Yes, many modern "common street cars" have a "corrected" gauge to display 90 over a temp range, normally 75 to 105 and do not show the accurate real-time temperature.

Thank you so much! Thats an explanation that helps me a lot.

I complety understand today how the gauge really works, and I assume it may be different for a race car like the GT3.

I appreciate very much your help. Thanks!

Why is it then that whilst my 2.7 981 coolant temperature gauge maintains 90 degrees as you say, the oil temp gauge varies to show the actual temp? This is a distraction only since the last service at 40k miles. Prior to this it too showed a fixed temp, 105 degrees, which I had thought to be on the same basis as coolant. When the car came back with oil temp fluctuating the OPC didn't know whether it was right or wrong and it took a while for PGB to find out that oil should show the actual temp and coolant 90 degrees.

Is this because oil temp is a better indicator of something about to go wrong (apart from a burst rad) than coolant temp?
