<VV> Reverse Rotation Cooling

[Mark Durham]

Yes, water cooling was used for that purpose.  The reason. Fcor the
teardowns was the engines were run past their normal continuous HP output,
usually for takeoff. I have seen mist type systems on cars which did the
cooling trick but did not over stress the engine. Mark Durham

It also eliminates or at least reduces any carbon buildup in the combustion
chambers, which might eliminate some carbon hot spots.  On a slightly
different tack water injection has also been used for a major power
boost...  this was done on WWII aircraft (on which my father was a
mechanic) and probably could not be made to work in this capacity on a
Corvair engine.

He also mentioned that the engine had to be torn down after a certain
number of accumulated "water injection" minutes were reached.  I can get
details from him if anyone wants them, though I guess wikipedia would
probably yield far more accurate results than his memories from 55 plus
years ago.
