Andyrew,
Levi is incorrect... True, water boils at 212 degrees, BUT that is at atmospheric conditions, not in a pressurized system.
The boiling point of water actually increases approximately 3-degrees for every pound of pressure.
Therefore, with a 16-lb pressure cap, the water will stay liquid until about 260 degrees (far greater than 212)... Your water should not see 260 degrees unless you really have problems.
100% water will provide BETTER cooling efficiency than a 50/50 mix, as the WATER conducts the heat better than coolant. Coolant has a higher boiling point, but water is more efficient. Unless you will exceed that boiling point (~260 degrees) the coolant ineffective.
As Sammy mentioned (page 10), you don't want to run Straight water because of corrosion reasons.For the BEST cooling, straight water with Water wetter and/or some other additive to prevent corrosion and possibly reduce the surface tension of the water .

Oh thank God, finally there is someone that knows every fucking thing there is to know about cars, I guess I can finally quit giving all my incorrect advice.
