Let me start by saying I like this design. ALOT! Infact, I would like very much to replace the ugly coilpack on my FFIM'd 7m car with a slick hidden set of coils like this, but I refuse to dive into a swap without reviewing all the variables, and with coils there is one specific one that I am concerned about.
I read the entire thread and did not see a single mention of "DWELL".
Infact, the word isn't mentioned once. ...so does anyone happen to know the dwell timeframe on these coils vs stock? I mean, that's a pretty integral part of coil swapping, and you are likely overcharging/heating the coils or not charging them well enough if you are using a non-stock ignitor.
If anyone wants to get scientific about this, say the word. Lets track down a o-scope and see what how those things stack up. ...anyone wanting to get defensive without any data (or even a basic understanding of coil charge-time), don't waste your breath.
