No, they are not unsafe when used as designed. They still have well over a 2
times safety factor for the pressure they are meant to hold. Welding tanks or
more like a 4 to 1 safety margin. I remember when nitrous bottles were iron
and weighed a ton, but racers DEMANDED lighter bottles, and many companies
supplied them. I am sure NHRA has a spec they muct meet, and if there were no
Yahoos putting pipe plugs in place of the relief valves, there probably would
never be another bottle explosion.

I have only seen one car with an air shifter. I don't know for sure, but I
thought he just filled it with an air compressor. I am sure 175 psi would be
plenty to operate the shifter for a couple runs. But if those bottles are
over 200 psi, then they should have the protective cage or they are running
illegal.

If you want, I can look up nitrous bottle specs. I won't name any names, but
I helped a guy put a cheater NOS system into a drag vehicle, and the bottle
was a tiny featherweight thing to give just 50 hp for 6 seconds. He only ran
300 psi of nitrous because the bottle walls were so thin. It was hidden in
the hood scoop of a removeable hood, operated by radio control with just a 9
volt battery. He jets the carb rich, and NOs just makes a fog over the it.
It is amazing what some people will do for an "edge"
This was not even in a car, so don't worry about the guy next to you at a Pro
Solo just yet.
