Water by itself if a better coolant than coolant. Water is extremely efficient, you only put coolant in to stop it freezing in winter and to stop rust and limescale inside the engine. If I lived in a warm country I'd ude de-ionised water only in my system.
Water also has infinate octane, someone should start using water injection (water injection isn't for cooling, like most people believe).
That's what I got told too.Not Necesseraly, You also add coolant as it raises the boiling point of the water, the pressure in the system does this also.

But raising it's boiling point doesn't raise it's efficiency, which is what I was referring to. People were saying that he should be careful with only water in there but it makes no odds, as it'll be more efficient with just water.
Raising the pressure using a 1.3bar cap raises the boiling point to 130.9 degrees c. Most coolants are based on anti freeze mainly as road going temperatures are rarely so high. Even with the standard 0.9bar cap the boiling point is 123.4 degrees c.
