So coils don't degrade with time, gradually accumulating small breaks, some rust, etc. and this doesn't affect its performance? Those 90k+ coils don't typically also mean mid-high mileage wires and plugs either? Nice to know coils work perfectly and then decide to just not work one day. Oh, wait.

You have just made a heap of assumptions based on no real facts. Your just guessing or predicting.
Well done.

You ever worked in mining or industry with HV gear, yes insulation breakdown voltage drops over time (and coils may degrade slightly), but when it gets down to system operating transient levels **** lets go (generally completely burning out) in a hurry, it doesn't "fade out".

Take a pill or something. Don't start another one of your rants because you don't like what I've experienced first hand.

It's funny how Slides was the only one that even attempted to address the questions and poorly at that.

I'm not speaking solely on insulation breakdown, although that has an affect. For any with some actual knowledge on this subject they know that the coil windings themselves will develop small breaks over time, especially when handled roughly. This alone increases coil resistance and degrades its performance. Over a long life, even with a protective boot coils can develop a tarnish on their output as well. If it's a smart coil then the electronics inside degrade with time and have a finite life span, although, that typically means odd transient behavior and not so much overall degraded performance. Etc.

So no, coils don't just magically stop working, there are methods to track their health but in the automotive world anyway most don't.

dguy - Sounds like that's exactly what you're trying to do against my first hand experience.

Where have you mentioned your first hand experience? I don't see it, and making a post illustrating my personal experience and then responding to a snarky comment hardly constitutes a rant.

All that you have done is bemoan an 'unfair' comparison without providing any evidence to the contrary. Call my 'evidence' anecdotal if you'd like, but don't even think that its cool to respond to my comment the way that you did and then even THINK about accusing me of going off on a rant.

Thanks much to Elliot for his testing, makes me feel better for migrating to IGN-1As for the configurations I've been building requiring onboard igniters.

Are you going to refute the nature of how coils age that I've stated and is fact or continue to attack me? I don't particularly care to address your "expertise" or mine given the facts are on my side and as such have no need to fall back on it to make a point. Furthermore, You have also conveniently forgotten the key word in your own post, "start", which implies it had not been done yet. Then you went and did it anyways. Good job.

Reread my posts. You're acting like a keyboard cowboy.

Keep attacking me as opposed to my argument.

Hey guys maybe I can clear some things up. This was my car that I dyno'd the coils on. Basically i did my single turbo upgrade and left the factory ignition on looking for 420 hp. i was getting a good bit of breakup when tuning so i knew i was going to need a better ignition. but i wanted to dyno for ***** and giggles. To initially try and fix the breakup I went with NGK 11.5 heat racing plugs. This helped but did not cure the issue. I wasnt going to waste money on a twin power i just bought the AEM coil packs made a bracket and wired them up myself for cheaper than a twin power. The 2 dynos use the same plug setup. One is factory ignition and one is AEM ignition.

Thanks for posting this. I'd be interested to see a compare between good/newish OEM stock coils with Twinpower vs the newer IGN coils on a PFC...... May have to look into that myself sometime

someone send me their twin power and i can get some o'scope shots, Im curious how it works
