Very very nice!!  This is exactly what I'm aiming to do!  You are ahead of me!  Haha, I can't wait to get caught back up with this replication, I have fallen behind it seems.  Keep up the excellent work!

1. I have 4 microwave 1mf 2,000 volt capacitors. Could I not use them in parallel with 2 of the hight voltage diodes from the microwaves to do the same as your schematic or is there a reason to use so many capacitors and must they need to be polarized?
You can use 1micro fared capacitor,Insted of 4 steps use only two steps of voltage multiplier(requires 4 caps), use 4007 two diode in series insted of single to make it workable with higher voltage. go for higher voltage use both 12V transformer to get more voltage. Higher the capacitance(mfd) higher current discharge
2. did you measure the amps (or better watts) consumed at the 220v input to do one explosion?
No, It is transient current difficult to measure
3. how much water is on the sparkplug before explosion?
I use pen cap on the spark plug top it contains 1 CC of water, It takes two blast to through out complete water
Remove resistance from spark plug(If present). I use meco spark plug No internal resistance present in it. Make sure diode sustane high current discharge, some times it gets shorted.

more experiments can be done with
use TYN612 600V 12 Amps SCR in series 3 nos (1800Volts@12Amps) as switch for discharge. Insted of relay, to prevent pre arcking in relay
high frequency ferrite core transformer can be used for fast charging of capacitor

YOU CAN TRY WITH MOSQUITO KILLER BAT, IT WORKS NICE, it takes very less current and gives very high plasma out

Hello and Namaste capacitor70. I am sending you a personal message. Please look for it

...remember that they usually have a built in 1megohm resistor across their terminals
(to stop repair men getting a shock).

In order to control the intensity of the discharge, would it be better to replace the coil with a hv power supply and just piggyback 110 or maybe even 220 onto that for the output?  The distributor could trigger the hv power supply via relay (across the source 12v).  Sounds like a good route to travel, as the coil is very inconsistent in it's spark output.  I think it would be better to use something more constant.  What do you guys think?
