Xboxhacker,
where is your first sparkgap in your picture Image 0122 ?

capacitor70 is using 3 capacitors in series to make the capacitance smaller
BUT to have a higher voltage rating of the whole capacitance,
so these 3 caps in series stand much higher voltage
as the breaking voltage will add up, when you put them in series.

So if your single cap is rate for maximum 2000 Volts,
3 put in series can withstand 6000 Volts.

Hope this helps.
Regards, Stefan.

Thanx  i just wanted to know for sure! 

The spark gap in the photo is just out of frame on the left, i just put the red aligator clip close to ground to make the gap. In the shot, on the left you can see a spark gap tester, i can make the gap on it .010" to 1.5" thats what i was useing originally as the spark plug on the primary side, this way i could move the gap with ease, if i need more or less.

The image is not showing the sparks, its just a image of my coil...thats all

Hmm,
when I look at the circuit some more,
I guess it could be much easier, not to use at all an ignition coil,
but just drive a big current pulse maybe with only 2 or 3 windings
into one side of the toroidal transformer,
so on the other side you will get a much higher induction voltage
to get this voltage to add to the low voltage high current side.

So we could probably reduce this circuit to just use the right toroidal
transformer and pulse one side of the toroidal
transformer with a 12 Volts pulse from the car battery via a transistor or MOSFET
and get rid of the ignition coil and the sparkgap.

This way we could save again many parts and generate the required
high voltage pulse.

You draw it...i build it 

Please try it this way.

Surely the green coil then needs to have only about 2 or 3 windings,
so the red coil will have at least 20 to 30 turns, so the
high voltage will be generated.

Also play with the polarities, cause you need
to generate a voltage on the red coil side that adds up
to the low voltage and not opposes it !
Pay much attention to this !
Use a scope to verify the polarities !

Many thanks.

Regards, Stefan.

I will try i laterz when i get home...have to work for "man" to keep the lights on..LOL

THIS WILL NOT WORK

V1       N1
------ = -------
V2       N2

if v1 is 12V then V2=(N1 X V2)/N2

Transistor and coil circuit is simple transistorized ignition system to drive HV coil
