My Emag was oddly efficient...

[iownamag]

Hello all, I have an emag with retro valve and some other goodies, you can check it out in my sig if you want, and I use a nitro duck adjustable 68/45 tank with it. Last weekend when I was playing I got one fill to roughly 4000 psi and I shot about 1400-1500 rounds before I got it filled again and even then the gauge still read about 1000 psi and it was still goin strong. Is it just me or is that kinda strange? I guess it could be cuz I'm used to using a 45/45, but even so it seems like a lot of shots to get out of a tank especially on a gun which I always thought of as a gas hog... for instance my friend has a mechanical mag with retro valve, norise, etc. and he has a 68/3295 (thats right, I said 3295 psi.) and he only gets about $500 shots out of that tank.

Level 10?

[iownamag]

yup, course . Could that be it? all my other mags and my friends mag have had/has lvl 10's as well...

I posted up a run down of what to expect in Automags and barrels with tanks in a post in Workbench. Its near the top.

What is your output set at. I run my at 600 psi, and get at least 7-8 pods and a hopper on a 4000 psi fill.

I hear that the input should be at least 800 psi

yea, that's true, if you want reactivity and a decent trigger in manual. The lower you can run it without hurting performance in electro mode, however, the better your efficiency can be.

Thats the recommended input pressure. But if you read the manual, it says anywhere from 600-800psi is just fine. I only use my E-Mag in E-Mode anyways so I doesn't matter if I get trigger bounce or not.

Personally even if I am shooting in manual, I want to be pulling the trigger, not having it bounce on me.

please explain this...

Because if you are only running 600 psi into the gun instead of 800 psi. You are saving air with each shot? Over the course of an enitre tank. That 200 psi difference in each shot begins to add up.

but it uses the same volum of air..

Your putting out less pressure though. Take your adjustable put the pressure at 800psi and let it drain out. Then take it and put it at 600psi and let it drain out. Which one takes longer?

This has always been my understanding of it.

[speeddemon]

tank pressure doesn't matter, even if you drop it down to 600 instead of 800, then the mags internal reg drops the pressure to around 400 no matter what the input pressure is. So the only thing that dropping the input pressure does is slow the recharge rate of the gun down.

Input pressure won't do anything (well maybe a bit if your shooting really fast, but you won't notice it) for efficiency.

I read Rob's post about it and found that it was mainly due to my using the stock emag barrel, and my tank was set at 800psi so I don't think that effected it much.

Speeddemon- I'm pretty sure your not correct on that one, because if that's the case then how come when people turn the pressure up to like 1000psi they can bounce it like crazy? I'm pretty sure it works like this... the pressure goes in from tank, the pressure goes through on/off valve at whatever it is going into the valve at, and then the pressure is regulated between then and the bolt. Other wise with a level 10 the whole gun would be running on 80 psi and I just don't think that'd work. If it can't push a bolt hard enough to break a paintball it would make for an awfully soupy trigger.

[speeddemon]

It is impossible to reg the air after the on/off valve, because it leads straight into the dump chamber, which of course is regulated air. So the dump chamber is filled with air regulated to about 400 or so psi. Look at the diagram of the valve. And if the valve is between the on/off and the dump chamber, then what is in the rest of the valve in the back?
