Ahhh, another documentation challenge!

well, let's see . . . in my over instrumented daily driver (302 fi)  
the engine oil starts to warm before any water is circulated  
(thermostat opens).  In order to warm the oil the luminova water would  
have to come right our of the engine.  Conversely, to cool the oil we  
would want the luminova water going into the engine from the radiator.

In my daily driver during the majority of the duty cycle, the engine  
coolant temps run a stable 195 +/- a few (195 thermostat).  Coolant  
exiting the radiator varies greatly - 50degrees during morning start  
up to about 190ish when the cooling fans come on.  Coolant temps have  
yet to exceed 200.  the oil temps seem to run between 195 (coasting  
down the mountain) to about 210 during a hard climb up the mountain.   
(thus my concern that I "may" need an oil cooler for track days)   
Pretty amazing oil temp control in that little ford motor.

the daily driver, btw, is a miata w/ a 302 - part of the conversion  
process is mating the miata gauges to the ford mechanicals.  When I  
got this I had no idea what anything was doing, what the gauge reading  
meant, when the fans were coming on/going off (easy larry) or anything  
else. I found that the "normal" miata gauge reading was really 160  
degrees in the motor (which was in cold startup mode all the time) and  
the "almost on the peg" reading was actually 195 - right where I  
wanted it.  Fans come on at 185 and go off at 170.  I now also know  
that the motor that wouldn't rev past 4000 rpm does - the miata tach  
does NOT.  Lesson?  If you don't know what you have . . . why do you  
want to change it?

After all these years I must admit, the Pantera oil is probably toooo  
cool most of the time.  It IS nice to be in the pits in p'rump w/ 195  
degree oil while everyone else is sweating temps and squirting  
coolant.  (Go Larry!)

cheers,

David in Durango, still grouchy and dirty but fully instrumented and
informed.
