Lets Talk About A/f Ratios

My thoughts on this....
Raising the melting temperature of engine components is pointless, from a power standpoint that is, not from a safety standpoint.There is no reason to exceed the melting temp of the stock components, more heat doesn't equal more power.The adiabatic efficiency of most engines is poor(and I would assume past a certain point it decreases even further as cylinder temp rises), so past a certain point, most(if not all) energy produced as heat is wasted.

Stoichiometric(14.6-14.7:1 for gasoline) is where an ideal chemical reaction takes place(enough air to completely burn all fuel), theoretically this should be where you get the greatest power and emissions, because all available energy from the mixture is released.But in reality its more like 12-13:1, which is where I would assume the adiabatic efficiency peaks.I would also assume the reason turbo cars like 11:1 or so, is because heat increases with pressure(via the ideal gas law), which in turn makes the adiabatic efficiency peak at a lower point.
