Timing effect on temperature at idle? retarded for cooler?
This is an odd question, how does timing at idle affect engine temperature(coolant/oil). My car idles flawlessly with a 230/250 cam all the way down to 8 degrees of timing and also idles great at 22 degrees of timing, obviously different sounds and rpms. I am curious for summer which way should I push it? I would imagine retarded timing runs cooler allowing more gas in the chamber before combustion, but before i go with trial and error, I figured I would just ask the experts. Thank you in advance
