Re: Running Hot Elixur ??
>How would the timing affect the temp?
Advanced timing runs hotter (yet develops more power, as long as you're not detonating). Retarded runs cooler.
The why of this is that the flame front takes a certain amount of time to spread through the cylinder, raising pressure and generating heat as it goes. If you give the flame front a good head start (advance your timing), pressures will be much higher by the time the piston reaches top dead center, and higher still as the piston descends, generating a lot more power (and heat). Note that it takes more energy to arrive at TDC in this case, but the net effect is more power (and heat).
Conversely, retarded timing means the flame front is trying to catch up with a soon-to-expand cylinder volume, and combustion pressures never rise as high as they could. Retarded timing thus means less power, less friction, and less residence time of a burning mixture in the cylinder, so less heat.
I hope that makes sense.
