I am interested in your thoughts regarding Evans Waterless Coolant For rotaries and older classic cars (1950s).
Have you had experience with the product?

People have used it in aircraft.

What is questionable is the coefficient of heat transfer between the coolant and the metal. I would test it with a thermal couple "cyl" head temperature device. Just because the coolant is temperature x does not mean the metal is being cooled.

Ian swears by Evans in his Renesis RV7 here in Perth.
He likes the minimal expansion and high boiling point.
He did lose his previous RV6 and rotary to overheating and a burst hose.
He has his cooling working well even at our high summer OAT +40c / +104F
