My friend, this is nothing new

I have already tested this in one of my guns, see Super CPS or something like that. It was a CPS 3000 connected with one and later two Power Paks
The only problem here is that the water flow from the tank on your back is weakened by the long hose, unable to keep the pressure and power of the original, built in CPS chamber. After my CPS 3000's chamber was emptied, the range droppped down from 13 to 9 Metres or something like that. not that effektiv, but therefore you have massiv volume
I am planing to build something crazy here, but not the time yet

Connecting CPS guns directly with the CPS power pak hose sounds stronger than it perform in reality then
nice greetings
