REFLECTOR: Thanks

[Brian Michalk]

Water is an excellent octane booster, which is why some modern cars 
recirculate a small amount of exhaust back into the intake manifold.
I've been wondering about installing water injection to aid with high 
power operation, as well as cooling on the ground.  A one gallon tank 
would be good enough for maybe up to one hour of ground ops/high power 
ops.  Depends on the operating regime.
