AL-XG took his QEV (shuttle piston type) to 750psi and used it that high regularly. Eventually the piston tore, so he replaced it.Daltonultra wrote: As for the piston breaking, it would take FAR more the 400psi to do so. I believe several people here have taken that model of QEV up over 600psi without consequence. The button-valve is also rated for 300psi, but it could be replaced by any number of other valves that are rated for much more.
There is no doubt in my mind that a QEV would increase performance, but whether it would be noticeable is a different matter. Cannons like this aren't just about power anyway.
