Yes bill there's alot of guys running co2 because they don't want to have a mechanical failure like burning a air pump up.
And yes you would need some sort of a regulator and a activation switch and then you would introduce the supplied air into the PV cavity
Damn bill your a quick study I had to search the turbo forums for this info but nobody wants to give out to much info they act like this stuff is rocket science or something
But I hope this helps
