What is the ideal voltage to a spark plug?

**Nobbsie** · 19th June 2015, 16:02

My question is if you where running say 16-18 volts to your spark plugs would there be more spark?
Would this more spark ignite the fuel better?
Which in turn would run better?

I think it maybe a little bit more than 16-18 volts at the plug.

but do you think that could be a thing?
19-21 volts?

This thread is cancerous.

...DO NOT TRY THIS AT HOME...i've heard that 240 volts makes the whole fucking tank ignite...does that help...

I think the question you are asking is - would you get more power. If so, the answer is hideously complicated. Try getting a book on fuel injection and read about things like flame fronts and the like. I don't remember the voltage presented at the spark plug ever coming up in relation to performance in any kind of serious way.

But more than likely, your manufacturer chose their ignition system parameters after a lot of careful tuning.

yea that is what i am asking,
it was just a thought,
but i will definitely look into it more

Start with the ignition coil, it's the bit that makes the 10,000 to 20,000V spark.

If you up voltage on the coils supply side (assuming you can do this and it isn't already a fancy CDI version), you'll fuck it cos there will be too much current/heat.

ah thanks Bogan that puts things in better perspective for me

Im thinking your thinking about the prim side of the coils. If your after more spark then its different coils as an option and researching would be a good idea to see what other people have used and the results for your bike. Maybe better spark plug type is the even better idea.

oh my bike is running sweet for now it was just more questioning and thinking and trying to understand the best i can

And put your bike in the profile so people don't wonder what bike your asking questions about.
