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.
Comparison of Turbo’s and superchargers
Both work on the same principle they blow air into the engine under pressure. Both have a turbine which spins up depending on the engine speed and the higher the revs the greater the volume of air is forced into the engine. But there are some major differences between the two and which is best for your project?
Principles of porting an engine and big valve conversions
The inlet and outlet ports on the engine block are usually larger than those of the manifolds that connect to them.
This allows for scope in the manufacturing process to allow for mismatched alignment.
Generally the engine ports are larger in the upstream flow direction avoiding turbulance but power gains can be made by matching these up.
