kinda like oxygen, non flammable, til you mix it with anything, then It becomes super flammable

for a hybrid,couldent you use n.o.z along with propane to up the power to even more insane levels? :D :twisted:

Well NO2 is a non-flamable gas.(very ironic) it is a powerfil oxidiser. I belevie it needs soming to burn on like propane or some other gas to burn on. (i believe :?: :?: )

And when it is burnt it seperates into oxygen and nitrogen which makes a hotter and more powerful burn but also extra fuel is needed to be added to the equation because of the extra oxygen released.read up on it on performance car sites they explaine it all.

what if it was in a galvinised steel hybrid.when my uncle david was a kid,they welded the seams closed,put in dry ice,and it went to 1200 psi.he said the threads,the weakest part,are rated to 1400 psi.they shot dowel rods with nails in the end out of a 3/4 inch,8 foot long barrel.they made a steel piston-like valve,but it worked a little different.So,couldent the steel support the pressure of a n.o.z and propane hybrid?

better ask your uncle how the valve worked!!
A 1200 psi valve is just what we need

i believe that there is something in hybrids with powerful fuels that the pressure spike is enormously more powerful that just 1200 psi in air. i dont have much experience in that, but i do know that someone filled a balloon withoxygen and acetelene and light it up in my afterschool welding shop. NOT FUN!

The nitrous oxide is just adding more oxygen and allowing more fuel to be burned, so it is the same idea as adding compressed air. So, the gun will just have to be build out of schedule 80, basicly like a hybrid. If anything, this is a great idea. It can be metered like propane, and will be more portable than hauling around a big compressor or air tank.
And yes, nitrous is an oxydizer. It will not burn on its own, but since people think that ammonium nitrate on its own will explode, I can see why. People are idiots.
