You may get different opinion on this issue......

To me, this is the optimal temperature range for modern engines.

If you race in high altitude area, I think it is safer to limit 125 C as the max. point.

Maybe Roelof or AFM can answer this Q better than me.

Sorry, I don't do drifting. I don't know.


Perhaps you can ask drifting tires in Electric On Road thread.

I know a Nova racing engine in a 1/10 tourer can get 125 to 130 C, I have seen simple Kyosho engines up to 170 C and my own Eagle 100 and 130 C with 2 different pipes and a Sirio 3.5cc on 85 to 90 C and some engines I test only 75 C.

In other words, there is no right number to tell. Be sure there is smoke to see from the exhaust and the engine performs good without hickups then the temperature will be OK.

I dont use temperature to tune my nova .12's. I always richen until performance just starts to drop off. Then lean it enough to get full power back. With the body work of a sedan you not going to like the temps you see. So dont look! I think there is to many variables to expect temps to always be a certain number. air temp humidity, air presure, sunny day or clouds. Just have it tuned right.

thanks guys. I hv ran the engine this morning. Actually it's a Falcon engine (think by M. Rossi) wow... beats my fren pants down in the long run.

Btw, it seems that the turning cornering such as s turn, u turn was kind of big radius... any tips on adjusting it better? but my servo seems to be optimal ends points already. Using foam tires on our normal vehicle on road.

btw, we don't use temperature to tune.. Its more of an overtemping issue.. some of my engines run like a raped ape at 250, some at 220 all depends on the engine, fuel, plug, shimming, baro, humidity, temp etc.

about 126 degrees C and you have to worry about internal lubrication problems and over temping the engine. Usually if the engine doesn't like how lean your running it you will notice it falling off in power, and often flame outs at the end of a long straight. Don't get me wrong some engines like to run there but you have to figure out how many liters you want the engine to last. Unless you take it to far to the other side, its a safe bet that parts will last a bit longer on the richer side. Reading the plug is crucial. cheers
