I long ago decided to run an electric water pump, but the other day I took out the MP book on the small block and read that the standard water pump at cruising speed pumps 70GPM. The high flow electrics brag about moving 35GPM, what am I missing here? At Idle the elecrtic has a slightly better flow, but the moment you hit the gas the standard one leaves it behind.
Thoughts or corrections.

I think it has to do with the fact that most cars that run electric do so because of horse power needed for a few seconds and not for normal driving. JMO
 
if this is for a street car i would think a mechanical fan would would be the best choice...
