Plasma Ignition | Plasma Jet Ignition

[Aaron Murakami]

Here's some pics of my installation, the wires on the truck now are Magnacore but I have a pic of the other ones that are ready to connect directly to my plugs that I modified with solid core wire below the stock wires

I don't know how long that stock coil will last with the cap discharge - might be a good idea to replace with the pertronix one at some point.

IF your HV output of the coil is positive HV, then add diodes like this - diode cathode goes to the wires that you have T connected into the spark plug cables above the boots - the anode of the diodes is connected to the + of the ignition coil because that is where the + of the capacitor in the MSD is connected to:



IF the HV output is negative, then reverse the diode direction.

How to check for HV polarity of ignition coil output - read Jetis' post #5 really simple: http://www.energeticforum.com/renewa...rity-test.html

You could test with one diode connected to a plug that is grounded to the valve cover or something - try both direction to see which one makes the plasma. Then you know what direction to place all the diodes.

MSD Connected

I now have my Street Fire MSD unit hooked up to my Tacoma and it drives fine!
WOW! I was doing a spark plug test with one wire out and a plug in it to see how strong the spark is and it was jumping spark 1 1/2" to 2" away to ground when I lifted the plug up from the engine ground! And doing major popping sounds!

I guess I'm now ready for the next phase of connecting the diodes??

Thanks,
Ron

Hooked up now

Have you hooked up the unit to your car and ran it with just the basic MSD ignition?

Faraday88 thank you for helping me, unfortunately I’m a little confused about your diagram. If it isn’t to much trouble could you please label some more of your components you are trying to show me. Thanks Jeremiah

Jeremiah, if I may add my two cents here, Faraday made a schematic showing what you show but added the ignition points and points capacitor in an electronic form schematic.
What I would like to ask you is, are you connecting one end of the capacitor at the ignition coil high voltage output and therefore adding another full length ignition wire (or low voltage wire) for each cylinder? Correct me if I'm wrong, but I believe Aaron just runs it under the ignition wire boot that goes over the spark plug.

Notice that during running the +12 volts usually goes from the ignition switch through a ballast resistor and then to the + on the ignition coil. The - on the ignition coil goes to the points and gets connected to ground when the ignition points are closed. The capacitor (sometimes called the condensor) usually inside the distributor (but sometimes on the outside of the distributor) is connected from the coil - to ground so it is in parallel with the points. Faraday shows the ignition points (when momentarily closed)connecting the +12 volts to the + side of the coil and the capacitor in parallel with the ignition coil primary, then the - side of the ignition coil permanently connected to ground. I don't think any auto manufacturer does it that way.
I did a copy/paste of this generic ignition system off internet but it just pasted the link instead of the diagram.

Here you go a little crude but it should do. [ATTACH=CONFIG]6989[/ATTACH]

Hey, Here is attached my explanation with the schematic hope that helps.

Ok I’ll try that, last time I had it from the plug wire on one end and then grounded to a washer under the plug. Is that correct? Thanks

Hey ,
Could show a sketch of what you mean? I'm willing to guide you.

Problem is I tried the ceramic capacitors and they wouldn’t work with for my application, I’m trying to use it on a points breaker ignition system and not something a magneto or cdi box. [ATTACH=CONFIG]6987[/ATTACH]

Use 0.47uf/600V SHMPP Capacitor in Parallel to your Primary coil...let us know what you get!

At $299 a set for my 8 cylinder I don't think it can work for me.

At hvstuff.com I can get; 30kV 330pF High Voltage Ceramic Disc Capacitor $0.79 each

But if money is no object then it looks like an easy way to go, maybe.

Likely need to experiment.

Off subject some but in anyone’s opinion there’s a company by the name Nology that makes spark plug wires the they claim can increase spark output from a capitor in the wire. From my understanding it’s a wire mesh sleeve that goes over the inner wire that causes resistance and ups the spark. They claim in can increase spark by 300%. Could this work, I know it’s a far cry from a plasma ignition but just asking. Thanks

Those are spark plug cables with capacitance built into them. Basically, just an extravagant peaking capacitor. I don't see why they wouldn't work with the plasma.
