great great write up!


"The hotter the air the greater tendency for detonation so the ECU dials things back. Forcing some cool air in there brings temps down quickly and effectively."

however, i think the reason for the detonation of colder air is better since its denser, not to cool the engine (although its a good side affect). In hot air, molecules tend to be excited and loosely packed (as in vibrating and bumping into each other, leaving spaces in between the molecules), while colder air leaves molecules tightly formed. This means denser and richer air, which ultimately means more fuel will be allowed to burn.
