I boil it out as you say.
Hope the heat exchanger works out.

In most cases 50/50 is the best solution. I wanted to try Evans
because
I have cooling overcapacity so the reduced heat transfer is no issue,
and the idea of running at zero pressure is interesting in terms of
safety. Furthermore the engine can safely be operated at a higher
temperature, which is good for performance. (This is not so obvious,
but
think about it this way: we ignite the fuel to get heat. Heat is what
drives our engines. All heat taken away from the engine is a loss of
energy. We should not cool any more than necessary to keep the engine
from melting.)
But now it appears the viscosity is a problem, so I'm back at 50/50.
Oh BTW I misunderstood your previous post, thought you were saying
that
with Evans you had cooler CHT's but I now understand you weren't
saying
that.

If you ever consider using Evans again, forget about their prep fluid.
Evans is a mixture of polypropylene glycol and ethylene glycol.
Regular
anti-freeze is pure ethylene glycol. So you can prep your engine by
pouring pure anti-freeze in it, and then drain it again with any water
that was remaining. If some droplets of anti-freeze remain it doesn't
matter as it is just one of the components of Evans itself.
And if you have water in your Evans you don't have to throw it away
but
you can just boil the water out on a stove. Or even in your engine if
you leave the cap off.
