With water pump systems the argument gets to be how fast to turn the pump, and guys worry about cavitation of the pump and surface tension of the coolant when trying to figure out how to get the best cooling.

One thing, though, is a constant instead of a trade off. If your motor does bust a gut by blowing a head gasket, you'll be much better off with pure water coolant than an anti freeze mix. The ethyl glycol does real nasty stuff to cylinders, pistons and rings when it burns off, while water just makes you look like Casey Jones as steam goes right out the pipe without doing that much damage.

A second thought - remembered this stuff called Redline Water Wetter. It's a snake oil that guys use in race cars to make water more efficient in terms heat transfer. The idea being is you can run more advance, leaner mixtures, smaller radiators, and make more power before it boils over.

You might take a look at the web page about it, even if you don't want to try the stuff, the page gives you lots of good info about the relative heat tranfer coefficients of water, anti freeze, iron, aluminum, and so on.

If you or Bill are having problems with overheating and the normal system flush and radiator cleaning isn't doing it -- and you have seen what anti freeze does when a head gasket blows -- you might want to try this stuff. Worst case is the giving a dead man an enema rule - may not help, but ain't gonna hurt nothin'.
