Lets look at the job of the coil in the spark system and see what it does.
Just as a power transformer converts mains 240 volts into a usable 9 volts for your charger or appliance a coil will increase the voltage.
A car battery/alternator will produce a paltry 12volts, certainly not enough to jump an air gap and create a spark.
An ignition coil raises the voltage in some installations between 20 and up to 40,000 volts and this allows the creation of a spark which can jump the air gap between the plugs.
Electric water pumps
In a performance engine you should never underestimate the need for adequate cooling.
All water cooled cars work on the principle of water being pumped around the engine and then to a radiator where it releases the heat.
Most water pumps are mechanical and run off the crank.
