what relation of the radiator cap to cooling down the water temp ?
A Radiator Cap can cause major overheating problems. Higher pressure cap can "capped" the boiling water circulating. Normally we use water + coolant, hence the boiling pressure is not that high.
But any value below 1.1 bar for high performance engine is a NO NO. Suggested Pressure Cap is 1.3 bar for track car, 1.5 for Drag.
