Redressing a controversial subject...

I had previously posted that I was was for the purposes of experimentation and fun , I would figure a way to attach 2 or 3 ignition coils in series to emit simultaneously occuring sparks, that would be joined together in 1 wire to the distributor cap.
My question is, would all the extra volts scramble everything inside the cap ???

A couple issues I see... the coil is designed for 30kV or so break down between the primary and secondary winding. Once you put them in series the negative of the next one in line will be at 30kV with its output at 60kV (with respect to ground). The primary needs to be switched from a floating driver that is not referenced to ground so that is design challenge number one. Next with 60kV - 90kV there is a good chance that the distributor would arc over internally as easy it jumps the gap. Lastly once the spark plug fires it will drop to the breakdown voltage of air across a gap and be pinned at much lower voltage than even the 1 coil puts out peak.. it only really makes this voltage for the time it take to ionize the air in plug gap. What value are you thinking this will give you?
