Increasing your working pressure allows your cooling system to handle higher temperatures and offer a higher static boiling point.  For every pound of pressure exerted on the coolant in the system, the static boiling point of the coolant is increased by 3 degrees F.  Keeping coolant in a liquid form allows the fluid to do it's job transferring heat to the radiator to be dissipated.  Coolant that is boiling cannot transfer as much heat and overheating is likely to occur.
