I just picked up an Aluminum 2" Cam and groove coupler yesterday,
Like this one.

I am going with an Aluminum 2" Chamber down to an Aluminum 1/2" Barrel then Anodize the whole thing when I'm done ( Mostly for looks ).
What's the most efficiant Chamber to barrel ratio for a 2" to 1/2" barrel ? I have looked on here and don't see much on this when using the old school design of Hair spray fueled ( Aqua net is my favorite ).
Barrel length ?
I was also thinking of going with a 3/4" barrel, but have not settled on that one yet.
Barrel length ?
The Ignition will be placed in the rear of the chamber using a single isolated wire in and it will ark against the Aluminum tube probably using a 1/8'' gap.
Thanks for the help.
P.S this is my first post in the combustion forum.
