Optimal temperature for a 1/10 engine
 
May i know what is the optimal temperature for a 1/10 on road 0.12 engine? Don't want to run it too hot. My case was ard 120 degC to 130 deg C... am i stressing the engine?

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.

ic. btw is it good to have a racing engine use for drifting? and which type of tires or wheel type to use?

asw7576 01-10-2009 07:42 AM

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.

Your 250 or 220 in deg F or deg C?

220-250 F............ 250C would melt engines lol..

so it's max. 120+ deg c

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

Thanks for all advices.

Btw, just curious, any idea where can i get Falcon TC-1 .12 touring engine parts? For future purchases if required.

It is GRP so (old) Ninja en GRP parts will fit.

viperviper 01-11-2009 08:16 AM

on the heatsinks it also stated design by M. Rossi so novarossi parts can fits?

Btw, any modern GRP parts can use too?

No, it is not a Novarossi production, with the .21 engines some things like bearings have the same sizes but I can not tell if the parts will fit.

Regarding the .21 I was told the new parts do fit older engines so I supose the .12 will do as well. On the other hand, get a GRP promo kit and you have an engine, exhaust and a cool cap for just 300 dollar

its always a good idea to find out what the manufacturer recommends on what is a good running temp, this will give you a ball park figure, my picco loves to run at around 105-110c nice and rich and good smoke where as some novas might run a little hotter, but at the end of the day temp is not the issue just a guide as long as you have good smoke(lubrication) use the correct fuel and plug and have good power your engine will run well:nod:
cheers
