I don't know how important the boiling point elevation of antifreeze is, but if the coolant is supposed to be at say no more than 110C (with pressure cap of course), then if you're going above that it's not a coolant issue, but a radiator capacity issue. If there's no radiator capacity issue then you don't need to be utilizing the boiling point elevation right? Straight water has greater thermal capacity and much greater thermal conductivity too, so it's not like the increased maximum coolant temperature is necessarily a good thing.
