What size wires are you using? 7mm or 8mm?
Since the summit coils were not subjected to high temperatures I am curious about the failure mechanism. If the primary to secondary winding ratio is large enough over stock then the secondary voltage could be exceeding the insulator breakdown voltage of the wire insulation.
(hotter spark)
The measured resistance seems to indicate this but there are other explanations behind the measured values. (quality and diameter of wire)
I sure would like to cut one of those summit coils apart.
Root cause analysis stuff.
Thanks

Yes, Summit took them back. I'm using new GM plug wires, think they're 8mm. I think the problem with the Summit/Accel coils was the 2 connection slots. They were too lose, didn't squeeze the terminals that plugged into them.
