<VV> Air vs Water HP

[BBRT]

John, I rarely disagree with you. However, you have given me the 
opportunity.  Your use of "during the run" implies drag racing or 
autocrossing, which are of short duration. The 89 uses a vertical fan assy. 
utilizing an Austin plastic fan. As you may be aware, the car was 
competitively raced both SCCA Nationally and vintage more recently.  This 
car has raced in very hot weather - road racing - without overheating.  And 
the car has a very high HP output for a  normally aspirated Corvair.  Most 
who use the fan system state the car will overheat in just the opposite 
condition; idling, slow multiple pace laps or on the grid.

This topic should be on Fastvair, IMHO.
