effiency bad?

[Cocker Killer23]

What all can I do to get more shots out of my impulse, the effiency seems bad on mine.

[Awhislyle]

how bad is it?

[Loner4life164]

Go get an LPR kit at www.e-paintballoutlet.com

Unless your getting like 200 shots out of a 68/4500 then something's wrong, and try playing with your dwell settings.

[Cocker Killer23]

is about 400 off a 68/300 normal

[Cocker Killer23]

i just got it thursday. I don't really know what dwell is

[Loner4life164]

Read the manual.

[Cocker Killer23]

I did, the dwell part confused me

[Loner4life164]

Well, the Left side is moving it down, the Right is moving it up. This is what you should do.. durn teh dwell all the way down, till when you click it, it sorta keeps beeping.. then adjust maxflo to 180, and move the dwell up, chorno, keep doing that till u hit desired velocity. :D

[Cocker Killer23]

hey loner, did the jackhammer2 help your effiency much

[Loner4life164]

Not sure, testing it out tomorrow. :D

[Cocker Killer23]

does dwell have anything to do with effiency, if so how much?

[Loner4life164]

Something with how long the valve stays open.. I guess a lot if it's set up wrong? I dunno, just do what I posted earlier.. :tup:

[Cocker Killer23]

About how many shots should I get off of my 68/3000, its opperating at about 180psi.

[checkyourhopper]

Efficiency depends on the individual marker. But you definitely should be getting more than 400 shots.

For starters, it sounds like your dwell is a little off. The dwell just controls an opening that lets gas to fire the hammer. If your dwell setting is too long then you release too much air per shot. Every gun has a sweet spot for the dwell. You just have to find it. In general, you want to have your dwell as short as possible.

[Loner4life164]

Took me a friggin hour and 2 hoppers to set mine.. It's still not what i want, but I couldn't stand it anymore and wanted to play...

[thebluenu]

you should expect around 10 shots per ci at 3k and 15 shots per ci at 4.5k (this is for blowbacks anyway, a properly set impulse should be around that or more) - so 68/3000 = 680 shots

anyway, your manual might be outa date, mine was when i got it, my friends was..... so who knows.....

anyway set your gun pessure to 180 (make sure it never goes above 200 psi (BAD)) and adjust your dwell to whatever velocity

[Cocker Killer23]

I've pretty much only dry fired it so far, would it use more air dry firing then when used with paint?

[freaky_guy]

straight from wolverines FAQ

#7 How many shots will I get from my tank?

These values are assuming you can get a full fill. If a CO2 tank is not chilled prior to filling it will not be filled completely (18oz in a 20oz tank). In addition most fields can not fill to a full 4500psi.

For a 20oz CO2 tank about 1000-1200 shots as long as the tank has an anti-siphon tube installed.
For a 68/3000 HPA tank about 800-900.
For a 45/4500 HPA tank about 800-900.
For a 68/4500 HPA tank about 1200-1300.
For a 90/4500 HPA tank about 1600-1800.
All of these numbers are based on assumption that your dwell is set correctly for your air source.

NOTE: If you are using an LPR you should get MORE shots per fill than what is stated above.

Extra info on HPA tanks

Steel tanks will not get as good a fill as carbon fiber or tuff skin. When air is forced into a tank it is compressed (duh) This causes the air molecules to get "excited" and heat up. They also then expand. All HPA tanks will get warm when filled, but a steel tank actually gets very hot to touch. Fiber wrapped tanks do not have this problem to the same degree as a steel tank.

If you fill a steel tank to 3000psi it will get hot. Once you let the tank sit and cool off, the pressure will drop to about 2400psi. A fiber tank will only drop to about 2800psi.

Fiber wrapped and tuff skin tanks have to be hydro'ed every 3 years, steel tanks every 5 years.

It is better to fill your compressed air tank when there is air in it. You will ALWAYS get a better fill. This is because the more air that is in your tank at room temperature the less air you are adding and having heat up and expand in your tank.

You should never switch from CO2 to HPA or vice versa in the same day. One gas is hot the other is cold and all it will do is eat up your seals and o-rings. Switching from one week to the next, not a problem.

thats not a good way to measure efficency, you should put paint through it till it runs dry to check efficency...

and dry firing isnt all that great for your marker... putting paint through it reduces stress (or somthing like that :eyes: )

[checkyourhopper]

Damn, you dry fired your marker 400 times in one sitting? I don't have any proof, but that is probably not a good thing to do. Dry firing a few shots here and there probably is okay but 400 times. That sounds a little much.

[Skog]

dry firing is something that you should never do with an imp, it can certainly damage your internals. there should be a piece of BRIGHT ORANGE paper telling you that you must NOT dry fire your impulse, and it underlines the reason why, sorry mate, but you have just voided your warranty.

as for your efficiency it will be at least halved by dry firing (ie you will get twice the no. of shots if you actually use paint)

If you ever want to dry fire an imp you should put rag in the end of the chamber (where you screw the barrel in) to provide the necessary back pressure to cushion the internals.

Remember your marker was designed to shoot paint, not thin air

[Cocker Killer23]

well then it would be about right then, Thanks.

[Cocker Killer23]

It does say that its not Recomded, but it doesn't say that it will void your warranty, and an airsmith at my local shop did it, and I'm sure he wouldn't void my warranty. and just for the record I didn't dry fire it 400 times in one sitting, I dry fired about 50 times in each.

[Cocker Killer23]

But thanks agin for solving that for me, I thought it didn't seem right.:)

[checkyourhopper]

Okay. I wasn't trying to be a jerk about it or anything like that. It just seemed like dry firing 400 times would be way too stressful on the marker. Some people like Skog say you shouldn't dry fire at all. Others say once or twice here and there is no biggie for the purposes of making sure the marker is put together right after a cleaning or repair. Personally, I think dry firing 50 times in a row is still too stressful on the marker and I would try to avoid doing that.

If your efficiency is bad, then the most common culprit is the dwell setting is off. If that's not it, then you may have a tiny leak somewhere. I spent, no joke, something like 8 months hunting for my leak. I replaced every damn O-ring in my marker, or so I thought. A Smart Part tech, who was like the third one to look at it, finally diagnosed the problem correctly when he found that the inside of my hammer assembly was leaking. I replaced the hammer assembly with a new one and a brass hammer and the difference was damned remarkable. I can get 11 pods out of my 68/4500 no problem.

[Cocker Killer23]

well if skog is right about your shots being halved by dryfireing, then my gun should be fine.
