    The MSD serves more than just causing multiple sparks - at the basic level, it is still a capacitor charging circuit that dumps a capacitor into the primary of an ignition coil so the coil output is amped up compared to just giving the primary a 12v input from the battery.

    You can use any trigger, but need some capacitor that is charged up to a couple microfarads (uf) at minimum and around 400+ volts at minimum.

    The cap is necessary because the diode allows the low voltage cap (400 is considered low voltage) to jump over a gap (when normally thousands of volts is needed). That causes the plasma effect.

    NO !! That is not correct!!

    You need a capacitor discharge circuit attached to the coil to make this work. The MSD is a multiple spark (capacitor) discharge circuit that discharges it's capacitor several times each firing event. A single cap discharge is all that's required to get a single plasma event at the spark plug. But the MSD is good because it gives multiple plasma events every time it fires.

    The coil and diode can't work their magic without a cap discharge involved.


    PS -- Sorry Aaron, I didn't see your response before I posted this.

    Ok thanks I can pick up a MSD Street Fire for $149. I read the specs it says multi fire spark to 3000 RPMs after that single fire. Does that affect plasma spark at all? I’m not sure of the microfarads it puts out I’m sure it would be adequate. Also my coil has a 3.0 ohm internal primary resistor do you think this will be a problem or will I be able to use it.

    I just came across a CDI box from Pertronix that has multi spark all the way to redline. Maybe a better choice?

    Can you post a link to the exact Pertronix CDI you mentioned in your other post?

    The Street Fire is about 89 mJ per cap dump - it's around 2uf, which isn't much. After 3000 rpm, there can still be multiple sparks. Low rpm 6-7 per fire and as it goes up, it reduces bit by bit because the cap charging circuit can only charge up so fast.

    The speed that the cap charger won't change the plasma - just a plasma will happen whenever the cap does discharge. If it is once per trigger, then you get one plasma burst per trigger. If it is 6 per trigger, then you get 6 plasma bursts per trigger.

    3 ohms isn't much but I would recommend a coil intended for capacitive discharge systems. I like the Pertronix one because it is fairly low cost for a performance ignition with really low resistance in both the primary and secondary. 0.32 ohms primary - https://www.amazon.com/gp/product/B0...SIN=B002Q363XM only $45 delivered on Amazon prime. MSD has coils with much lower resistance if you can imagine that but they're a few hundred but not necessary.

    Aaron,
    Can'nt we custom build the Ignition coil, the secondary will have to be multi-layered with epoxy insulation.I guess it can be build much smaller also..

    $234 for module and all harness, etc. pretty good price.

    However, 187mJ per discharge is really strong and would eat your plugs more than twice as fast as the Street Fire if you use it for a plasma ignition system. Keep in mind that even with the smaller 89mJ discharge with the Street Fire that under compression with a lot of air/fuel getting crammed onto the spark, when the cap discharges over the plug, the plasma gets bigger than what you see in open air tests. The air/fuel and mositure in the air feeds the plasma. I think 100mJ per discharge or less is the way to go for regular driving and with good plugs.

    For performance where I don't care about how long plugs last, I'd definitely go with that Pertronix unit.

    Yes, but for $45, that is a better deal for me. It would take well over 10 times that amount worth of my time to do it by hand. I guess it depends on where you are and what economy you're working with.
