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.
Cryogenic engine treatments
When putting more power through an engine you need to ensure that every part will perform at its optimum.
One of the motorsports favourite techniques to improve the durability of an engine is a process know as cryogenic treatments.
As you can guess from the use of the word Cryo – it involves the cooling and heating of the engine block to temper the metal changing its structure.
