With an EWP and a digital controller, the speed of the pump is managed by the controller, which varies the supply voltage to the pump and so varies the speed of the pump, hunting for a target temperature. When the engine reaches the target temperature the controller locks on, constantly changing the pump speed with traffic and throttle conditions, maintaining the target temperature independent of the engine speed.

The important improvement for your vehicle comes from the fact that most of the power the mechanical pump takes from the engine can be reclaimed with the use of an EWP hence the fuel savings. By removing the parasitic power losses of belt-driven water pumps, the EWP may provide up to 10kw of extra power and additional fuel savings. The engine power used by the mechanical pump increases as the cube of its speed – so when the mechanical pump speed doubles from idle speed say; 600rpm to 1200 rpm, the power it takes increases by eight times. Then another eight times going to 2400 rpm, and so on up to maximum engine speed. It is this extra power and torque that is released by deleting the mechanical pump that provides the fuel savings that is estimated to be 3.5% to 10%.
