What?
cav.i.ta.tion \ kav' i ta' shun \ n [1. the rapid formation and collapse of vapor pockets in a flowing liquid in regions of very low pressure. 2. such a pocket formed.] (Webster)
Since cavitation occurs when the vapor pressure of a liquid drops to a point at which it boils or 'vaporizes' on a microscopic scale, reducing the static pressure of the cooling system should theoretically increase the chances for cavitation. I suspect the real reason that Evans coolant inhibits cavitation is not the unpressurized state of the cooling system but that it has an intrinsically higher boiling point (ie vapor pressure).
