From Novarossi site:
-The right engine temperature will vary widely, depending on the air temperature, fuel used, altitude, driving style, air flow conditions of the body and several other factors.
There is absolutely no way anyone can tell you an ideal engine temperature.
It is generally accepted that a proper range of temperatures is between 95 and 140 degrees Celsius (or about 203 and 284 degrees Fahrenheit).
The biggest variable of all in measuring engine temperature is where and how the measurement is taken.
Your infrared thermometer may be calibrated completely different than ours, or you may be pointing at a different spot on the head.
We usually check the temperature pointing the infrared on the glow plug.
High temperature with the new low profile coolingheads?
The results of test show that forced convection heat transfer rates can be enhanced by up to X using low profiles cooling design. With the low profile heat sink, the measured temperatures on its surface can reach 15 to 20 °C / 59 to 68° F higher than normal because the temperature detection is done close to the glow plugs.
