8V92 normal operating temps

[Don Bradner]

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.
