Some great stuff here Peoples. I really need to brush up on HV theory to get
on board with these experiments.
Ive started making my FireStorm plugs and got many of the parts at hand.
Hope to be able to contribute something here soon.

Great finding! This shows that we need to toy around a little bit more with this coils.
That may be the reason that different engines need different spark gaps for optimal performance.
In my little 25cc 2 stroke engine I couldn't open the gap higher that 0,8mm, 0,5 is the normal gap for that engine. I mean in normal conditions, working with gas. Just opening the gap to see were it could go.

I'm not at home these days so I'm painfully away from this project...

I still have a doubt, what about that bifillar coil? I retained the idea that cap70 got some good results with it!

@xbox
If its not too abusing to ask but I think that a relation between gap and pressure could be very useful.
A pressure gauge is cheap...

@rfsimoes:
The gauge i used was about 65psi.

The gap on the secondary side needs to be big to get a good effect. I have had it up to .065"..and WOW!!!! But that was at normal atmosphere....need more tests and data!!!

I am trying to buy some clear PVC or plexi tube to make a visible chamber to see the normal spark and then the water water spark reaction. I want to try to get it to about 100psi...i hope it dont explode when i do the water test... ...or is that what we want?? LOL

As far as i know, Cap70 told me that the Bifilar coil is a NO GO...it didnt work for him!!! As a side note, it didnt work for me either!

spark gap is having relation with voltage, at what voltage primary triggered is decided by the gap.  , more gap on primary more voltage....higher the capacitance of primary side, it is difficult to achieve higher voltage on primary side so less voltage on secondary. try to use high current ignition coil for this experiment. so that drop across all circuit can be kept minimum. also CDI ignition system gives little better results  , I have taken more test with coil, I don't see any disadvantage of little inductance of coil.  Try to take test with hydrogen, when you add extra neutron to hydrogen it becomes deuterium or can be made tritium as said by the Stan Mayer, I think spark plug designed by Stan Mayer are my first water fuel injector system and plasma.

Just for added info for those who may not know

I am a mechanic and here is some info on psi

Running psi is much lower than you think

If you pressure test a v8 engine say u get a total of 145 psi

Running psi would be around 65 tops, so it is not needed to have 100psi spark, not that it would hurt just letting you know that when an engine is running the psi is lower then when u do a compression test.
