Water has no corrosion inhibitors or anything that helps the water pump stay lubricated. Cast iron and straight water = rusty water.

If your car is overheating on 50/50 coolant, you have other issues that need to be resolved.

Staright water boils at 212 at sea level, 50/50 coolant boils at ~225. Since the 37 radiators are unpressurised, you want the highest boiling you can get.

...and God forbid you forget about the straight water being in there when winter freeze hits.
