Can anyone provide an reasonably accurate temp measurement for the rear differential on average or even at the track?

 

Not that it matters at this point.. but from what I gather temps on a tracked car(1/4 mil), multiple runs approx 110f, highest I found was 200f on a big truck under load, say 15k towing. As for what I was looking for , this answer my question. If you have data thats not a guess but actual seen temps, post em. Do us all a favor, if you dont know or doubt what I found, post up real numbers so we can all get something out of this.
