As best I recall, the old Racing Beat Technical Catalog specified that 180F
for the coolant leaving (of course the Mazda thermostat was set for 180F
which might have had something to do with that number) and 210F for the oil
flowing into the engines were the desired limits.  However, I think that was
probably a bit conservative at least with the later engines with their
different castings.  I have exceed those temps (as have most of us) without
any detectable adverse effect.  But if you go past 230 on oil or around 220
on coolant for any extended period you may be pushing your luck.

When I had the thermostat in, I was seeing it stabilize the temperature at
about 195 degrees.  Either my thermostat was a little off, or my temperature
gauge is off.  Maybe both, who knows.

Finding out now that I have no clue what my oil temperatures have been doing
are a big concern to me right now.  I hope to see when I get the sensor in
the right place that the temperature is in line.  If not, I may have damaged
the engine, but it seems to be running good, outside of the tuning issues.
