Haha. I am not the type of person to go with drugs though, I am the type of person who supports law enforcement and the military and hope to get into some branch like that. So drugs are a no no for me... Thanks for the link by the way.

I don't suggest gasoline vapors, as I recall the vapor pressure is only about 4psi, so it's darned hard to fuel with gasoline. I did however manage to fuel a spray 'n' pray by soaking a paper towel in it then letting it sit in the chamber, clicking away until ignition was achieved.
As has been said many times before on this forum, for any given alkane structure, the maximum pressure is pretty similar. You'll see no gains in 2,2,4-methylpentane (gasoline) over butane or even propane if you have the mixes correct.
