Small variable is the inlet temperature of the air.
And you are limited by either the hottest cylinder in the engine or the cylinder with the leanest mixture not all cylinders were cooled equally and not all cylinders got exactly the same mixture.
Hello all,
I am in the midst of a heated debate...
Lake, sea, or even tap water are far different from distilled water used for engine coolant, so most/all of the corrosion issues there won't apply. (cast iron and carbon steel will still rust somewhat with pure water, but to nowhere near the same extreme and will lack the even more problematic salt/mineral deposits and etching, not to mention potential hot spots and coolant flow issues caused by mineral deposits inducing boiling and steam gaps in the coolant -this is worse for calcium/magnesium deposits in typical hard water than it is for saline solutions devoid of bicarbonates, as calcium and magnesium bicarbonate turn into solid carbonate scum/scale at high temperatures)More glycol results a WAY less internal damage to the water passages. If you want a study in why water isn't particularly good for an Allison or Merlin, just take apart one that has been used in a boat where the lake or seawater was used for cooling. It isn't pretty, and sometimes results in extreme corrosion to the point of going through to the cylinders.
