Everything that you could ask is in the wiki. Whereabouts did you actually search? I would look into db ratios and other combustion areas before trying to build anything.
EDIT- yes. and try to use better grammar and common sense in your posts :D

If it increases that amount of force propelling the ammo, I think so. Yes. Why wouldn't it?

Welcome to Spudfiles, post some pictures of your mini when finshed, I'd like to see it.

Of course, were are my manners? I sometimes forget that some things aren't as obvious as they seem.
to clarify my first answer, performance increases until you reach a certain cb threshold and then its just wasted space.

How old is the spark lighter?... After to many uses they need replacing, grab both the wires in the lighter... hold them about 3mms apart facing each other and then give it a few clicks... if you see a spark between the wires it should be working fine.

As ajdevi92 said, make sure your not putting in to much fuel, otherwise there wont be enough oxygen in the chamber, and as we all know fire and combustions need both fuel and oxygen to work.
