[quote="codge"]I'm not sure the water side of a rotary is any hotter than a piston car? The exhaust certainly, but the rad, water pump, fan, stat system seems like a straight lift from a piston engine to me......???? comments please.[/quote

the rotary exhaust is hotter due to the continued fuel burn in the header, the exhaust port / mounting area on the rotor housing will be hotter due to radiation of heat in the bay and thermal transfer through the metal in turn making the coolant a higher temp / increase in temp quicker thats kind of were ive got with my understanding of the cooling system but i may be way off wouldnt be the first time ! .fez
