> The Evans cooling system is a serious engineering solution and popular in the
racing circuit. Works best when the engine block and heads have been well
flushed, leaving no trapped air products. The viscosity is higher and the coolant
has the appropriate water pump lubrication. The lack of cavitation phenomena
are a serious advantage. Operating at a higher net temperature is well within
the design envelope of modern european engines. I modified the cooling system
for my 2.0L Audi turbo install as per instructions from their chief engineer
and made an elevated bleed fill point. Biggest issue is running at zero net
pressure (psig) and taking into account the thermal expansion of the liquid.
Small impact on system flow as the water pump is not working against the same head
pressure. Fully degasified (about a week of running) gives impressive
results. I continued to bleed the system for about 2 months every other weekend.

Anyway, not snakeoil, but real hydraulic and thermal engineering!
