proper temperature ?
Hi,
what is the correct operating temp for a nitro engine ?
what is a dangerous temp?
i have been trying to tweek my engine and when i think it's sounding and performing well, it hits temps of about 240-250. where i bought it from said keep it at or below 210, but i have seen others say 250 is ok.
what is your opinion?
thank you
Dave

If it runs good at 250, then run it at 250. Also clean out the top of your temp gun with a cue tip so it gives a more accurate reading. My engines normally run fine at 220, but I tune by performance and smoke, closely monitoring temps though. So if it is at 270, neverless, I would richen it up. I try not to get much above 260 though.

Global warming might push the optimal temp up a bit but I would not run over 130 degrees for safety.

Throttle,
I break-in my engines over 250f. You need the high heat to properly anneal (stress relieve) and lap the P&S. In normal driving I run my engines between 220f - 250f. If the engine does not come up to full operating temp, ignition will be retarded, the header will hold too much heat and the sleeve will not fully (or evenly) expand at the top to relieve the pinch at TDC (this stresses the rod & pins).

THANKS GUYS,
i will try to tune it today.

Farenheit vs. Celsius.
Maybe we should agree on Kelvin
We metric people prefer celcius,, you pound, stone, ounce, gallon, yards, feet and all the other weird measurements can carry on.
