OK then that gives some creedance to my questions. If it's increasing engine speed then you are indeed giving it "fuel" and your burning it.
A 10hp shot of nitrous is not much at all. It's actually such a small shot of fuel that you have to pulse the solenoid to flow that little gas through a 0.02" jet at 40psi. (The nitrous is just an oxidiser.. as is the oxygen in HHO)
I'm headed out of state for a few weeks. When I get back I think I'll make one of these kits and give it a try on my 06 ranger 4x4. (daily driver @ 400 miles per week)
