Different twist on Speed/A4 parts in an IR3

[zuznon]

There have been several threads of adding speed parts in the normal locations on an IR3 just wondering if anybody that has upgraded to the speed board or A4 board and battery have moved the LPR to the other side of the marker?

Looking at the stock IR3 gas ports it doesn’t look like that hard of a change, it would require some machine work and some plugs.

Has anybody already done it and can share their experience?

With the speed and A4 board your still going to need the battery. So there wont be enough room for the lpr will there?

[zuznon]

The A4 is supposed to be shorter than the IR3 and Speed then where do they put the battery? Looking at smaller and still has a battery then where do they put it? I was under the impression that the A4/speed battery is a 4.6v and gets there by losing a cell. Here take a look at an exploded drawing from the Speed manual.

If you used the Speed/4 battery, you'd have enough room to put an lpr there. But you would have to mill into the air pasage from the battery side, and seal off the newly created lpr chamber from the battery compartment.

[NickDeveau]

That sounds like a lot of work... Why are you going to attempt this again...?

[RonnyMcDYO]

In an attempt to lower operating pressure, but this wont increase air efficiency, just so you guys are aware of that. In fact the A4/Speed when running a very low operating pressure is a massive gas hog. The only Speed part id try installing (and I m trying to install) is the Ram, but havent gotten to quiet getting one in there yet. Basically by installing the speed lpr on the battery chamber side, your giving the valve chamber added volume, to allow you to lower the input pressure, and to keep the gun from starving while rapid firing.

[NickDeveau]

Thats going to make it more inneficient just like you said, if you drop the pressure it takes more air and less pressure, to prope the ball; whereas less air but more pressure to propel the ball would allow for higher efficiency correct? So whats the point in dropping the pressure just to waste air?

well, if you see a speed or A4 with volumizers, its running "sub-200psi) as we all know, old shockers run at like what 180-220psi and those things are gas hogs. I think the Ir3 runs somewhere around 450-500psi something like that. So if sub 200 is too low to be efficient and 450-500 is too high for you, that maybe you should try to reach somewhere in between, It's generally agreed by most airsmiths that 350psi is ideal opperation preassure, or at least thats what I have heared.

[RonnyMcDYO]

Well you want to lower your RAM operating pressure, becasue the less air your ram needs to move, the more air you get for shooting the ball. So like you guys said somewhere in between is the best. Lower your LPR as far as you can, but keep your valve pressure up. In the IR3 the best way to do this is install a very light valve spring, some people use a cocker spring(valve spring I think), then you can drop your LPR to around 60 psi. Also you can use the Evil Angel Valve Kit, and im pretty sure it uses a much lighter spring and valve stem. This also means your ram wont chop paint, only pinch, unless its really brittle stuff, and with the lighter spring it will still open the valve. The reason I say put the speed ram in is because its designed to operate with less air pressure, so it should be better on the lower LPR of 60 psi. Im just not sure what it will take to put the speed ram in, for the most part I think it will just consist of extending the threading so it will fit into place, but im not sure yet.

200psi isn't necessarily inefficient, it just matters on how you have your maker set up. AKA guns are very efficient, and they run in this range. A little bit of experimentation should help you find the best operating pressure.

People have to understand the difference from something being the cause or being correlated.
Shockers are lp but gas hogs because they ineffecient, not cuz of lp.
So shockers are inefficients and also run lp. They don't cause the other.

Some angels can run into very low perssure like newr flys etc but it can reduce efficiency. If you run very high pressure it can cause inefficiency as well.
Lp basically allows reduction in chops so that why it was so important in the 90's because they really didn't have eyes to prevent it yet. THat is why it's semi important in Angels cuz they are semi prone to chops.

[RonnyMcDYO]

Yea rice crispi hit the nail on the head there, as well one point he didnt make was that LP does not make your gun efficient either, and like the entire post has said its all aboot proper settings. The only way to make these guns run on lower pressures is to find a way to expel the ball at the same speed with less air, cause thats where the air gets used up the most. Someone correct me on this if im wrong, but each shot uses 200 psi for the ball, and then whatever your LPR is set to, so in most cases its 290 to 300 psi each shot. Now if you can drop your LPR to 60 or 30 psi thats like 260 to 230 psi per shot a lot better. Now in the case of the new angels with larger volumizers on the valve chamber you have anywhere from 200 to 300 psi in there, with twice the cubic inch as there was in the older models, which is why they are gas hogs. So with the new guns just put the volumizer on your LPR side, and I say your going to be fine.
