Bill,
   Very correct on the water. Many racing sanctions also ban coolant as it
   contaminates the track when a radiator gets hit (we would never do
   that!).
   The lube/corrosion inhibitor we used is RedLine Water Wetter. We ran
   back to
   back tests on a USAC paved sprint car and had 15 deg F cooler
   running with
   water wetter. Don't know the chemistry of what they are doing, but
   it does
   make water transfer heat better. Allowed us to use a smaller radiator to
   reduce nose weight.
   Probably worth looking into for our rotary stuff as well. It may
   help some
   of the guys with marginal cooling.

Larry,
As a long time motorcycle road racer I know about glycol on the track!
In our racing it was an instant DQ if anybody saw Glycol in your
machine. Nothing is as slippery on asphalt! I swear I ran through a
puddle of RedLine 20-50 and it wasn't as slippery under your tires. I
used water wetter also. I didn't see as big a difference, but my bike
cooled pretty well to begin with.
