Ok I see where you going now!
Hmm...

I liked that pressure test but it's not imitating the engine correctly!
In the engine the water air mixture is hot because the fast compression.
And the space is a lot smaller in the moment of the plasma discharge.
That can make a big difference in the length of the pressure spike!

I know that you sad that you tried in the engine and fell on your face but it's may be some timing issue!

Would be nice to get an engine running with gas and plasma sparks first!
When I tried that it was not good, but the engine was not reliable!
Had mechanical issues...

I think that is the way to go: get it running with gas first!

@tiltfulll:
The engine didnt run because we didnt understand all the variables!

So i will list some variables, so we can conquer them. 

-Their is a certain primary spark gap setting to allow the secondary gap to fire under pressure, i have documented that in a video.
-Chamber size (as you stated, you 100% right)
-Chamber temp
-Secondary spark gap size... the bigger the gap the bigger the event!
-Secondary spark gap shape... Blunt, pointed, or round
-Water amount added
-Water temp
-Water type...tap, well, distilled....ect
-Water type in another form....steam, fog, mist....
-DC voltage
-DC amps
-Chamber pressure at fire
-Spark gap electrode material type
-Cap70 coil turn ratios
-Capacitor size on the primary
-Amount of cold beer on hand 

I am sure their is more.......

As for the primary gap to secondary gap relationship, i took to BRAND NEW plugs, one for primary and one for secondary. Both with stock gap setting, the secondary did not fire under pressure. More tests needed!

@Pvar06,

I think you are correct, a combo system would give more flexibility.... Have you thought of using a GEET set-up with a plasma spark ( Cap70 circuit)...Lets hear what you think??

No I have not thought of using the GEET system with Cap70 circuit. But in any case i am planning to use the combo system. I think such combo system should make out life easy.

Today i have tested out the Cap70 circuit but could not get spark at both the plug. I dont know what is the problem. Any way i will send you PM on my trail as dont want to disturb the advance stage discussions happening here.

Happy testing.

DEFINITIVE PRESSURE TEST w/ PLASMA SPARK.

I made a jig with a real gauge this time!!!

The start pressure is at 35psi.. and with plasma event with water it jumps to 75psi !!!!!! 

Great to see progress Xbox.

Well it seems that plasma ball is doing 75-35 = 40 psi
Could you try the next:
- gasoline drop with the HV spark only
- gasoline drop with the full circuit

and see what is the pressure then

that will save a lot of time for analyzes of what power is required for engine running

thanks again for sharing your observations.

@vlindos:
I already tried a drop of gas on hte plug while it was on the bench....a VERY small amount was suffeicent for a nice effect. I also made a vid with some gas on the plug, too much gas was used and it just started a fire. I dont think i want to try it under pressure with gas in a PVC test jig....LOL
