Ideal engine temp? 160,170, 190???
I was wondering what temps you guys like to run at for best performance? whats the benefit on both sides of the range? My engine spec is on my signature, and because the iron heads and street high compression (yes new cars have 11.0) I have always chosen 160deg. The other day the temp got up to 190 when my electric fan broke in traffic and noticed it felt different but not bad, performance felt simular but idle with my cam rose up maybe 100-150rpm. Was wondering if the fuel was atomizing better?
So what do you guys say? On the dyno have any numbers been noticed to be better or worse? Any difference at the track?
