a monumental waste of money.

voltage of the spark at the spark plug is a product of engine compression ( atmospheric pressure and makeup ).. and spark gap.

want more KV.. open the gap.

you can have a coil capable of producing 80kv there.. and if under compression at your gap.. all you need is 8kv.. then guess what... at 8kv.. the arc jumps...

don't try to over think this.. it's been hashed out for 100ys now with kettering....

I know the output kv will not be any greater than one coil but the amps should be double therefore more complete combustion and already have 2 coils to use so no monumental cost

voltage at arc is the same.

resistance is the same ( spark gap / atmosphere.

ever here of ohms law?

it disagrees with your reasoning.

where do you see 2 cils? or 2 maggies? airplane engines.. and that is just redundancy.. not increased spark ....

stay in school :)

Quoting Removed, click Modern View to see

If the voltage remains the same why do the amps increase?
