Electric water pump, worth while?
I think there's quite a lot of aero benefit to be squeezed out the cooling system, mostly by carefully ducting the air to and from the heat exchanger. One goal has to be to reduce the size of the radiator to its practical minimum. Does an electric water pump help at all? I'm thinking that the decoupling of the water pump speed from the engine speed should allow for quite a lot of improvement, if done right!
