random list of cooling system ideas i have.
1. You could run the electric pump while car is off to more effictively warm up engine via block heater. But they also make thermosiphon coolant heaters that do this aswell.
2. you could potentially combine this with an alternator delete and stop using the serpentine belt all together assuming your car had a serpentine belt driven water pump.
3. You could try and make the engine warm up faster by adding a valve to the heater core so it isn't warmed up when heat is not needed.
4. You could buy a thicker more fin dense radiator to reduce the size of radiator needed. But this has its own aero dynamic losses
5. You could increase thermal mass of the cooling system so that short bursts of heat like flooring it to pass a car won't cause your car to overheat. You could do this using a massive coolant tank like this one: Link removed as i dont have enough posts on here
6. in alternative to above you could wire the car to turn on the cabin heater when the engine starts to overheat.
7. you could stack an oil cooler in front/behind the radiator to have more cooling with less frontal area.
8. you could use a smaller pulley on the water pump to overdrive it and make it spin faster.
9. you can design your system with the expectation that the car will overheat in certain situations.
10. Instead of doing all this work you could go buy a toyota prius which has adaptive aerodynamic grill block which is basically what you want.
Fundamentally your car will likely over heat when the rpms are high. The engines already spinning the water pump very fast, im doubtful you will go much faster with your electric setup. You will also have some very high losses. 40-50% at the alternator, then more at the pump as it produces heat.
I was wondering what would happen if you integrated the radiator with the turnk lid and used a combination of a fan and the natural vacuum when the cars in motion to have cooling with virtually no aerodynamic losses.
you can always try to dissipate heat like the old porsche race cars did. By running oil through the car frame.
Alot of vehicles like the prius already use an electric water pump but thats probably more for the reduced warm up time.
