Mag' Air Efficiency

[MagMcBride]

Is there any way to increase the air efficiency of a mag? I just realized I only get like 500-600 shots from my 68/3k...and my buddie's "gas hog" shocker gets like 1300 from his 68/4500 Max Flo. (I have a Max Flo as well) Any help would be appreciated!!

nothing to do get a bigger tank f u want and if u had a 4500 ude get around 700-800 or so that should be enough

[MagMcBride]

dont have 350 for another max flo and I CANNOT find another reg that is anywhere as consistant as it (within 2-5 fps on the chrony)

If you have a level 10 installed, try using the shortest spring...that gained me a noticeable difference in shots per fill.

If you don't mind the noise, a less ported barrel?

Just get another tank for your reg, or sell the max flow and get a non-adjustable tank

500-600 per 68/3000 is pretty low. I was getting closer to 800 for a tank that size.

To start with, you're comparing apples and oranges. Put a 68/4500 on your mag THEN compare the numbers.

Then, what's your Mag setup? Barrel type/length, lvl10?, what spring?

Is your Max-Flo capable of accepting 4500psi input? If so, but just a 4500psi tank.

Actually in general the adjustable regs are generally more efficient than the preset counterparts. In addition the 4500 series regs in general are more efficient than the 3000psi ones.

Since you are using a 3000psi reg that limits you to 3000psi obviously. I don't know if a nice 4500 preset like one from CenterFlag would outperform the Max-Flow but you are wanting to keep it cheap right?

The "money is no concern" way is to get a nice high quality adjustable 4500 tank.

Umm. Accurate, consistent, maybe even more responsive or freeflowing ...

But Efficient?

I think you've got some terms confused.

An adjustable or preset set at the same output pressure should both provide the same number of shots.

Test it yourself if you don't belive me. As a matter of fact, this looks like a good time for me to make another addition to my rapid-fire thread. Here is what I will do.

Ill go borrow one of my friends 3000psi preset tanks and shoot it till its dry at a constant speed. Then Ill try the same thing on my 4500psi Max-Flo with the same input pressure.

I claim that I will consistancly get more shots per tank than the preset will. I might suggest you do the same so we can compare results.

Umm that's pointless.

Of course one tank with more pressure will shoot more than another with less pressure.

Has nothing to do with whether the tank is preset or adjustable.

Now, if you meant to comapare a:
- 68/4500 preset
with a:
- 68/4500 adjustable

Then you'd have a valid test. But besides pressure setting creep both should shoot exaclty the same number of shots when filled to the same pressure and emptied to the same pressure.

Sorry, forgot to metion same fill pressure.

All the same, how do can you argue that it's not fair to test a 3K reg and a 4.5K reg? If, as you claim there is no differnece in the total number of shots and I say there is, why not try an extreme difference in hardware.

All that would have to be made as constistant as possible is:

- the marker (including velocity and barrel)

- the input pressure

-the fill pressure

- the temperature of the tank and makrer (have to let them cool to room temp

- the speed at which the shots are fired

If I test that 3-4 times for each tanka nd try to keep those variables as constant as possible I would think that is a perfect test

Mag Setup

-68 with A.I.R. Valve
-Polished ss pf left body (with chrome PF Plug)
-12" 2-piece AA (Stainless Back)
-10" Dye SS
-Chrome Blade Intelli
-68/3k OLD MODEL Max Flo (On/Off valve on it is knob NOT lever!!)
-KAPP Chrome Gas-Thru Grip
-Input Pressure on Reg set to 900 (I like to keep velocity at 260 on my airball field)
-LX with custom spring (1/2 coil longer than the short one) with the second smallest carrier

Soon to be Wish List:
Chrome centerfeed ULE body
Chrome X-Valve

Once again I only get about 500-600 shots from my tank and it has always been like this, not a recent thing (Put the Max Flo on a 02' STO and got about 800 shots out of it).

Tested at the same fill pressure no problem. Otherwise you're proving the rather stupidly self-evident thesis that a tank with more pressure will shoot more shots.

My only beef was with the fill pressure.

To make the test properly informative, you need to take the tank pressure before and after the taest. And the fill pressure of both tanks has to be cold and stabilised.

There may indeed be a difference in number of shots. But it will be due to regulator design and not preset vs. adjustable. Although it's highly likely that the average preset is a better designed regulator than the average preset.

The difference will be due to how much input pressure (that is tank pressure) the regulator requires to give the desired output. Also how much the regulator output varies with respect to tank pressure will have a large influence over shot to shot consistency, recharge rate, etc ...

If a particular regulator gives more shots per tank, I'm certain it will be shown it's because the final pressure in the tank is lower in the regulator that shot more compared to tank pressure with the regulator that shot less.

And of course there MAY be differences is actual tank volume ...

[speedyejl]

Your joking one regulator being more efficient than another?

Try explaining how and why do your test to show that its impossible.

Unless their being over-pressurized or leaking air or something, regs don't vent air, they only send it in one direction, explain where the loss of air is going there.
