"FlowKooler water pump impellers prevent engine overheating through higher flow rates and increased system pressure. Increasing flow rate of coolant through the block reduces the cycle time between the engine and the radiator providing more opportunity for heat exchange. When flow rate is maximized, the higher flow rates raise block pressure to prevent the formation of steam pockets and water vapor that can cause hot spots on cylinder walls. This block pressure can also prevent engine damaging cavitation"

No data on flow as a function of RPM or HP. The impellers although large
are not curved.
