If the power supply is 3000v, the cap will charge higher than 3000v because of the choke that will show you higher voltage spikes coming out, which charge the cap higher than the coil. Take any output from a coil, run it though a diode and choke to a cap and the cap will charge above the source...you can see it on a scope. You can see an example here...sirhoax does some great vids and I found this long time ago when I first started to use the chokes to limit current on the wfc projects these spikes on the scope are of course above what the power source is and if you have a 3000v power source, you'll get more than this in the cap, guaranteed:

And we know that rate of change for dc is what is really important for increasing voltage and not the turns ratio..therefore super fast rate of change of 3000v into a choke...I think is more than sufficient to beat the necessary voltage.
Of course the current limiting abilit of the chokes magnetic field isn't as relevant here seeing that the spike from ignition coil is mostly potential anyway but the collapse of the choke sending a higher voltage spike than what came into the cap is relevant.
It has been said that the ignition coil by Gray was modified and probably had few turns for for the specific purpose of higher frequencies. This is common on some of the interesting ignitions system patents...most of the ignition coils are modified - even the Suckewer patents tell this...secondary has fewer windings.
At 3000v/mm, that is 6.35mm for a 1/4 inch or 19050 volts to jump 1/4 inch. A 3000v pulse going into an inductor and the inductor collapsing I think will have no problem reaching that voltage.
About the cap soaking up the spikes, I have stated this ... while stating if the front side cap is charged up. because otherwise, the cap will soak it up...I have pointed this out at least once right here in this thread. The cap is the low resistance path for the power supply as long as the cap can take a charge. This is why I have said with the cap "charged up" in the references to this because if the cap can't take any more, where else is the hv spikes from the ignition coil going to go? To the grid.
I see you address @all on the listening issue and the reason I said what I said is because I think it makes no sense for anyone to mention about not listening, especially when it has been posted by myself and others over and over and over and even in this exact thread. I have used the balloon popping analogy many times clearly showing that the potential itself is NOT a spark or arc moving to the grid as the source to charge the coil. This one single concept has been the most common explanation for how the tube works that I've seen since Peter's book came out..hv discharge into the lv rod...the the magical event moves to grids to power the coil...even though it hasn't been spelled out what the magical event is...but I think I explained what it is in my opinion as others have.
The only spark I ever mentioned moving from the rods to the grids is what I found with the ignition coil with LV switch open without a cap or with a charged cap. I have even gotten two events from the ignition coil at the exact same time...plasma burst at the gap of the rods PLUS a regular HV spark to the grid off the same pulse.
