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 performance under ever-changing racing conditions.
