Re: Special cooling for Rotax ?

Graham,
I would add that specific heat capacity also takes a nosedive upon the addition
of antifreeze to water. Not that this matters during steady state conditions,
but it reduces the thermal inertia of the system and the ability to cope with
short term peaks.

The fact that Rotax have gone from an antifreeze mixture of 50% ( I think it
was) to 100% is, IMHO, indicative of a shortcoming in head design.
