REAL GOOD IDEA on spraying the aux coolant at the hottest part of the
inner water jacket around the spark plugs. Even if it turns to steam and
escapes. Converting water to steam sucks up a tremendous amount of heat.
I would use a high pressure pump however to maintain the pressure through
out the several gallon quantity in the aux tank.

Good idea, but perhaps a bit excessive.  I opted for hard plumbing and
Aeroquip hoses with AN fittings (-24 is really big) for my
cooling.  Pressure tests indicated that the water pump seal is the first
thing to blow.  If you plumb coolant like this you won't have to fret over
connections and hoses, just the water pump and metal fatigue.  Did anyone
mention dual belts or a backup electric water pump?  While we're preparing
to fly the ice cap :) might was well  ....
