Subject: Re: [Amps] SS amps watercooling
There are waterless coolants used in automotive applications. Evans seems to be
the main manufacturer in NA. The main advantage is that its boiling point is
way higher than water + antifreeze. This means that the operating pressure is
near atmospheric and allows operation at temperatures that would cause
overpressure issues with water based coolants.
Whether it is useful for this application is unknown to me.

## Dont even think of using Evans waterless cooler......its snake oil,
reserved for the middle of the night infomercials. 7 guys here in town blew
their engines up using that crap. Its basicly 100 % glycol.
100% glycol will raise the boiling point sky high. Like 300 ++ deg F.
Problem is.... 100% glycol extracts next to nothing for heat transfer.
What ends up happening is the CHTs... cylinder head temps, will skyrocket,
damaging the engine. The stuff still wont boil of course, since its boiling
point is through the roof. Your typ 190 deg F T stat on your eng rad is
not much use either, it starts to open at 190 F, and is fully open by 205 F.
It doesnt cool the cylinder heads at all, and they keep going up in temp. Its
pure junk, plane and simple. Forget all the BS testimonials, they really
should be tossed in the slammer for selling it. Folks have also tried using
the evans
junk in water cooled motorbikes, same deal, cooked the cyl heads beyond
recognition.
## On my mustang, they monitor the CHT....and not the actual coolant temps.
The coolant temp is derived from an algorithm inside the ECUs software load.
