2 ignition coils

[goatnipples2002]

Would it be possible to wire up 2 coils and run them off the same ignition controller? I thought about splicing 2 coils into the same plug ins for more spark. The only reason I thoughjt of this was because I saw some guys that had 2 coil packs on there "sunflowers" I mean sunfires. Could a hotter spark do more hurt then help?

anything is possible...i ahve found that out

Works for airplanes... and NHRA

I don't see why not. You'll need some reliable way to splice the output wires together. Try asking the small plane owners at your local airport if you can peek at the ignition systems their planes use. Just me thinking out loud here - can the stock dizzy and cap/rotor take it?

are you sure they aren't running 2 plugs per cylinder??? I have heard of that before. I don't think regular spark plugs or wires could handle that much voltage without disintegrating. I'd definitely read into this a lot more before trying it.

[goatnipples2002]

I don't plan on using stock anything if I do this.

msd makes a tach splitter for the plugs that go into ur coil. My thought was to plug both pairs of coil plugs into 2 tach splitters. Then plug them into the ignition control module as normal. I will get an msd ignition control module, msd dizzy cap and rotor and msd 6al ignition controller. 96,000 volts would be sick

I'm not sure any spark plug is made to withstand that much voltage going through it. The main reason spark plugs need to be replaced in the first place is from the wear of electric current. The gap increases because the electrodes wear away from the spark. Doubling the voltage through it doesn't equate to half the life. It could blow the electrode in half or break the insulation apart rather quickly, and could cause some broken pieces to be left floating around inside your engine. And the same goes for the plug wires and your cap/rotor. Assuming that it would work, I really don't think there would be a lot gained over just going with the MSD coil with larger, less resistive wires, and hotter plugs. The 2 plugs per cylinder idea helps a little since there are 2 seperate sparks in different locations in the cylinder. The idea is to speed up total combustion in the chamber.....it comes to a limiting factor of how quickly the eplosion....after the spark....travels throughout the cylinder. The spark is only meant to start this explosion.

Well I talked to the guys at MSD and they said it would be a waste of time and effort in trying rig 2 coils. He said that no matter how much voltage I throw at my plug they only accept so much. Or someting to that effect.

Well, you could always go with plugs made for alchie burning funny cars
A high performance coil along with a spark amplifier would probably do the trick.
LOL @ 96,000 Volts screw buying fuel, you'd get 300hp running on SPARK!!!!

Speaking of your 85 GT, still got the nose cone?

Afterthought for FierceGT: I used to have an 82 Datsun 200SX (May it rot in hell forever) with a dual spark Inline 4cyl. If I remember right, it had 1 coil, one dizzy, 8 wires and 8 plugs. At least I THINK it only had one coil.

[FierceGT]

I imagine in a case like that.....well I suppose either case....sending a voltage through 2 wires, or to 2 different spark plugs, the timing would have to be precise. You would want both signals to reach the plug or plugs at the exact same time. So I wonder if the length of the cable and the resistance in each wire has to be exactly the same? It's a great concept of two seperate spark plugs, I believe Dodge is working on it for their Hemi engines, and as Ragtop says...it was in his 82 Datsun so the idea has been around for a while.

[goatnipples2002]

Yeah I still have the nose cone but it is wrped in the middle

[RandomTask]

Yeah, well the plugs in top fuel dragsters and alchie funny cars only last one run down the track, then they're toast...

i dont think that both plugs fire at the same time i think only one fires, the reason for the dual plug is for fast rpm pick up, u figure you have a v-8 all 8 plugs fire durring one cycle, if you have a 4 cyl. with a 8 plug dist. then the motor would fire fast cause it to run faster and harder but thats just my opion.
