Are you referring to the radiator cap? The higher the pressure rating on the cap, the higher pressure the cooling system can reach. The higher the pressure, the higher the boiling point. Boiling is what you DO NOT want your coolant to do, as it will create all kinds of bubbles and air pockets, which could lead to a blown headgasket if any of that air gets caught in the water pump. Raising the pressure helps keep the coolant from boiling so it can more effectively carry the heat away from the engine.
Most of the JDM aftermarket caps like Mugen and Spoon are rated at 1.3 bar, or around 19 psi.
*edit* I think 1.1 bar is right at 16 psi, so the 16 psi cap would be the stock-rating replacement. I would not recommend going lower than 16 psi.
