Interesting figures.  I've heard (can someone verify this?) that if heat
conductivity figures were included, the high coolant ratio figures wouldn't
look so encouraging.  Someone once told me that conductivity decays only a
little less dramatically than the boiling point increases.
Say it ain't so .... Jim S.

Hmmm. I'm using about 90% coolant / 10% tap water.

What are the other flyers using?
