8V92 normal operating temps

Which prompted me to ask this question: What are normal operating
temps for the 8V92? My coach runs ~200-210 on the freeway, ~220-225
when climbing a long grade. I've never seen it hit the 230 mark,
though. Is this normal? And, what would you all consider to be the
emergency shutdown temperature, also known as the point at which the
driver poops himself trying to get the coach off the road and the
engine shut down as quickly as possible? Would like to know, in case I
do have a problem some day, would be nice to be able to save the
engine. :-)

Ryan, are you talking water, or oil? Water at 220 would be a
disaster-waiting-to-happen, oil at 230 not so bad.

With the digital readout from VMSpc, the highest water temp I think I've seen is
201, pulling a hard grade at 100+ degrees ambient. My analog gauge has no
readings between 190 and 220, which makes it hard to get anything exact there. I
have often seen 230 on the oil temp, although an IR gun on the pan does not
confirm that (reads lower). The engine computer doesn't output oil temp.

If you look at post 22995 you can see what my bus does. It was in chart form when sent but grouped together. Look at the column headings and follow them to the numbers below L to R. If you can't figure it out I will email one to you if you want it.

Whoops. Yeah, I was confused. I was thinking about oil, Pete was
talking water. Nevermind!! Appreciate the replies though.

Oil shows 200 ~ 250 as "normal" in my Blue Box book. I have
occasionally seen near-230 on a steep grade. I doubt that the 8v92
would be much different than the Series 60 on oil temp.
