6v coils on 12v

boler76 · Mar 30, 2013

talking can coils. what would the results be of hooking two 6v can coils in series on 12v and joining the hi voltage leads together for added zip

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

Then look at it this way...The more connections you'll have the more chances you'll have that something will go wrong. More connections to keep clean and tight.

On the other hand...if you have the time and coils and just want to see if it'll work then go for it.

The motorcycle world was overrun with 6 volt coils many years ago. You'd have two 6 volt coils in one simple bracket for a cleaner installation. Just saying.

If you got some mad machinist skills you could engineer a second distributor on the other side of the engine. Use one distributor for cylinders 1 & 3. The other distributor for cylinders 2 & 4. At least, then, if one screwed up you could limp home on half your engine. N's will do that run on 2 cylinders thing.

Why mess with something that works? Because we can, that's why! You go Boler76! Get 'er done!

With the 2 secondaries hooked together, they will discharge into each other & not jump the spark gap.

(quoted from post at 03:56:02 03/31/13) 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

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

well I will abandon this idea thanks

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
