I have a custom coil on plug set up.

Dynatek ARC2 and 0.5 ohm coils, I have measured both the current and voltage on this set up with my own equipment. I'll try to collate the data and post it up in this thread.

"This is testing of my CDI system, for current flow, primary voltage, secondary burn time, number of spark restrikes....

Burn time is roughly 420us or .4 milliseconds and there is 6 separate restrikes at 1000rpm over roughly 5 milliseconds per cycle. System pulls about 25 amps of first spark and 13 amps for the restrike sparks."

I have pics of my CDI system in my car thread, takes too long for me to load up that page to find the exact picture though lol.

The power of this system is great, it can out do the HKS DLI and stock ign coil and lead by a long way (run the car much richer and maximum level of water injection however like all CDI systems very low speed running *idle* in particular is not as good (burn time way too short as shown) as what you get with an inductive ignition even with multiple sparks. The longer duration offered by transistor is superior, once engine speed is up the CDI is superior.
