3/4 vs engine temp....don't confuse the two.

No one has substantiated what the engine temp (and what does that mean, to use a Clintonism...) is at 3/4 scale, in terms of head temp, where on the head, or water jacket temp, and where on the jacket? There is a little temp sender right near the thermostat housing that sends the signal to the gauge...this is the point at which water jacket temp is measured and thus is the starting point for engine temperature discussions.
On my car (the only one I can say for sure) an 82C thermostat will yield a gauge reading of below 1/2, probably 3/8 if one continues the metaphor. Therefore, any temp reading above that indicates the radiator temp is above 82C. This seems to be confirmed on my car by infrared non-contact thermometer (Raytek Minitemp) readings on my radiator. With the temp reading about 1/8 below the red (still in the green BTW!) the Raytek reads about 193F or about 89C. My radiator has a low-temp VW thermoswitch labelled 82C.
