Ok, since I cannot find my stupid cam, I will solve it up^^
I have connected a CPS 3000 with a Super Soaker Powerpack. It looks nice and is easy to wear, the powerpack was put in the backpack with the reservoir.
The QFD is working great. When the four pressure chambers are full you hear the PR-valve inside working, this is time to stop QFD. Also the bladder of the CPS 3000 is "stronger". When the power pack's PC is full the CPS 3000 is about 3/4, just when no water can go into the Power Pack the PC of the CPS 3000 is filled up to maximum. I stop filling when the CPS 3000 is full.
When firing it is working great! The CPS 3000 and the power pack are emptying all "about" constantly. This way you always know how much water you have left about. Not that exact what you might think but a good help

THe CPS 3000 is empty when the Power pack holds about 400 ml. THis time the pressure falls off a bit.
When starting firing you have a crazy pressure, then it drops off a little bit(after 1 second of firing), then holds pressure and then, when the CPS 3000 is empty, falls off again a little.
Range of 5X :: 12 metres, then drops off to 11, in the end you have 10.
Range of 10 X:: 12 metres, drops off to 10,5, in the end you have 10
Range of 20 X:: 11 metres, drops off to 9 metres, in the end down to 8-7 metres(does not matter since this is not even 1 second firing till the CPS is all empty)
Typhon: untested
When using the 20X:: the CPS 3000's PC is emptying quicker, It seems that the Power pack's flow is not or too less to power the 20 X:: with a good range, that is the reason why the power pack originally does not have a 20 X:: stream...
now to firing time :
5X :: 21 seconds (hahaha)
10X:: 12
20X:: 7 seconds
This says the 20 X:: fires about as long as the FLash-Flood but pushes not 350 ml but 4700 ml on your oponent in the same time hahaha
The pump is smooth and I am able to PUMP UP THE CRAZY PC VOLUME WITHOUT STOPS, in about 30 seconds. Then I am out of power...This says, at 33 ml/stroke I have to pump about 143 times.......
The Soaker is a great weapon in a water ware. It can drown other people with its water hahah. Just go around and soaker others, and when there is some time pump a little bit to keep pressure up. Even if you are trigger happy, this is no problem, but keep in mind that even 4700ml are out soon at 20 X::...
Fortunately I installed a QFD for those who are to lazy to pump. I would suggest to fill up by QFD, then fire and pump in during the firght on the field, and when the water is out just go to QFD and refill hahaha
Only drawback is that it is rather heavy. When you really refill by QFD and fill up the reservoir backpack with its 25 litre maximum you may hold about 30-40 kilogramm on your shoulders...Thanks that the backpack is so comfortable to work. The good thing here is that you can als use it like a QFD-Soaker. No water in backpack just using the QFD and filling the PCs. THis way you only have about 5 kilogramm on your back

But I will refill by pumping most of the time, so I can stay on the field for a loooong time
You CAN run with it, if you have the power to ^^ It is stable and strong, also comfortable, it won't break if you fall during running but it's weight may kill you whe nit is completely full hahaha
I have NOT taken pictures of producing, since I cannot find my cam. But I will get you pictures and may open the gun again, just for you
Woohooo, a big project is done
ADD: FOUND MY CAMM!!!!!!!!!!! Give me some time to write up a "bulding process instroduction" with pictures for isoaker

I think this would be worth to put on isoaker.com ?
