I could be wrong but don't funny cars and top fuel dragsters run 2 wires per cylinder, I could swear I've seen it or at least heard about it before. Not sure of the reason unless it's for the "wasted spark" your talking about. I always thought they where for a backup, a redundant system, so if one fails there's one to back it up.
I never got into the more advanced workings of ignition systems, I put in my msd box and looked a few schematics to trace wires but that's the extent of my knowledge.

the book nate just wrote is true.. but that doesnt change the fact that the car is dumb.

I do not think that is related. I believe the ones you are thinking of have 2 sets of plugs, and pretty much two ignition systems.

does that motor use a hall switch? i dont htink you can use a coil per cylinder with one unless you had two triggers?

^^^i thaught they had 2 ignition systems also, they do have 2 distributors

I am pretty sure that car is using megasquirt with a ford EDIS ignition system. You can see the trigger wheel on the cam sprocket and the pickup. It is possible to run a 4 cylinder with sequential ignition with that setup.

EDIT: I take that back, it is not using a Ford setup. But, it is using some type of ignition system with a trigger wheel and VR sensor...

I am not sure which system, but it surely could support the COP.

[harwood39]
