What temps do you guys look for. I am running a RB s3 L2G and i am running arouns 190 with a 50 degree ambient. Sounds about right?

IMO the correct running temp for a .21 engine is 200-230F. You need to get it hot enough to where everything expands to the correct tolerences. Not saying 190 will hurt it though, especailly with a 50F ambient temp. that should be hot enough. If it is running well leave it.

Also you really don't want to tune only by temps. You also want to watch for smoke, preformance and sound. I do check temps to make sure it's not too hot and to make sure I am going in the right direction, but the other three factors come first.

Agree with the above, forget the temp just use it as a reference point if in doubt but in no way as the main decision factor, tune by performance response and sound.

I know that is what i am doing, just don't want to run too cold and wear it, or run too too hot.

A nitro engine can really get up to 290F before any damage occurs. It can also be the colling head. Some very efficent heads like the grp tuned run at 170-200, and some more non-efficent engine heads run at 270.

Yeah that is true, but the general .21 nitro engine runs + or - 30 degrees from 200F.

Chris- I got your PM, and tried to reply, but I am getting an error message. Says you have chosen not to recieve private messages. Just an fyi, as to why I didn't reply.

Alright so if ambient is like 70, and i run 240 thats about right, maybe a little lean, but hey, if it's running good like that i can leave it right?

Yup 240 is not too hot at all.

Chris, sorry still not working bud. Might be something in your settings.
