Hey guys what is a safe engine temp for racing .21 3port race spec, on a track with a .30.00 second lap time. To day my motor came of the track at 205.temp after the 3 heats and a 20:00 minute.main, it had good smoke all the way down the front straighaway, it seems like I could lean it out on the top or bottom?. Comming out of the corners it kinda bogged with goood smoke, could some one help me ? The plug I was running was a #5 rb concepts. It's a hot plug.
