*Why is increased Pressure Better?*

It’s simple.  When water is pressurized, its natural boiling point is increased.  Most modern vehicles are equipped with a 0.9 Bar pressure cap.  Koyorad’s Hyper Cap is rated at 1.3 Bar which increases the boiling temperature of your coolant to 267.80 degrees Fahrenheit.  That is nearly a 56 degree increase over water's normal boiling point.  By increasing the boiling point of water, an engine's cooling system will have the added heat capacity, maximizing perfromance under ever-changing racing conditions.
