only combustion..im at my dads and i forgot my air compressor
| Quote: | | what mix do you shoot at? |
i plan on taking it to 5x maybe 6x but only after many tests at 5x and before 5x i will test alot at 3x and 4x
| Quote: | | also, how are the spark plugs set up? |
they are in a series.. the stun gun wired to the top of one and the bottom of the other.. then wires going to each other to complete the current

You know, i'm probly just missing them, but i have yet to see a hybird connon on video in action, like i said i'm probly just missing them, total bummer for me!
I'm wondering if wiring the spark plugs in a series robs the trailing spark plug of some power??? Do you have a digetal muti tester with a high voltage plug in?

| Nice hybrid... though, your barrel could be a LOT longer. Right now, your chamber to barrel ratio is around 13:1; a good hybrid chamber to barrel ratio is 0.3:1...

I've been waiting for this 
Its always good to login and see another hybrid posted.
You might end up going supersonic with a longer barrel and a high mix(evbec calc'd 1200fps with a 144" @4x)
Anyway, everything looks really clean and sturdy. If I had to complain about something I'd say your spark gaps might be more efficient if they were placed near the middle.
Would I get a prize for guessing whos on the tv?
