You need to mod the QEV for chamber feeding if you're using a blowgun, basically unscrew it, poke a small hole through the diaphragm (NOT the part that covers the seat, between the seat and the valve wall) and put a small spring between the diaphragm and the rear of the valve.

I don't think tape will cut it, epoxy ;) remember it doesn't need to be more than 1mm diameter.

I covered the hole and changed to a 1.5mm drill bit (the smallest that will fit in the chuck) and put the hole in the right place this time (i put the big one that's covered where the thin rubber is :L) and it works but with my bike hand-pump i can get 2 shots from it, if i get a fridge compressor and take it to about 55 bar will i get lots of high power shots?

can you post it before you take it to 55bar, that kind of pressure is nothing to be playing with.
