All Edelbrock water pumps are designed with the aid of the Edelbrock water pump dyno.

Designed and built by Edelbrock, this dyno is set-up to test water pumps in a "real-world" setting that simulates the conditions of an actual engine. The "coolant" in the dyno is pre-heated to reflect the actual temperature of the coolant in a running engine. The sensors collect flow numbers, temperature and pressure data as well as how much horsepower is required to turn the water pump. This gives us the complete picture about the efficiency of the water pump design.
Finally, the information is interpreted, recorded and stored by the Edelbrock QwikData data acquisition system. Using the QwikData system gives the engineer the capability of creating graphs and viewing the information in any number of ways.This testing is used to develop water pumps that will exceed the additional cooling system demands of a high performance engine. The chart to the left shows the flow data collected on our two Circle Track water pumps. Note the even distribution and amount of flow up to the high-rpm range.
