Just a quick about the volumizers...

[Hedghog]

Just got a used A4 and noticed that the volumizer was fitted to the left-side of the gun (holding as you would shoot it). I have read that it will make no use on this side and I want to change to the right. If I do so will I need to adjust the LPR?? I don´t have the tool-kit... :-(

No need to change the LPR. Just put it on the right side and you'll be fine.

Also how does it really work.. first stage reg, seconstage lpr..???

I'm not sure if you got to shoot your A4 before you bought it but in theory you shouldn't have to adjust the LPR as Trigga Nometry states. But if you experience a lot of drop off I think that might be something you'll want to check in the troubleshooting process.

Check out the recommended setup link on the front page of the A4 forum... I had Bob @ fixmyangel service my gun right after I got it (used) and he set it up like this:
LPR: 55
minireg: ~200
Dwell: 14
Med Volumizer (on exhaust valve side)
TR: don't remember (but I put it @ 1 and I'm don't experience any bounce)
I had him install the Mag Trigger Mod and Slayer Trigger (he bent the leaf spring for me to make the trigger pull really really light and responsive).
using an LP tank also btw.

the volumizer lowers your operating pressure and increases the amount of air you have available, i don't think it has any effect on your LPR.

Volumizer Functionality
The Angel has been designed to accept volumizers that attached to the front of the Angel. Attachment of volumizers will allow the working pressure of the Angel to be reduced to suit specific customer requirements. The Angel volumizer come in 3 sizes that will reduce the working by approximately the values shown in below.

· Each volumizer will change the operating pressure of the Angel as follows:
– approx 325psi (no volumizer)
– approx 275psi (shortest volumizer)
– approx 225psi (medium volumizer)
– approx 175psi (longest volumizer)

As stated by lefty, it lowers the operating pressure, lowers efficiency, lowers kick, and raises the coolness factor of your gun (I think so). Unless you have drop off, lpr adjustment isn't required.

[Trigga Nometry]

If you are only worried about adding the "coolness factor" and not want to change anything else, just add the volumizer and change nothing else. Instant coolness!

Ok, but do I have to change the velocity myself with the minireg?? It was at about 200 when I bought it.. whill I have to lower it to the values shown in the manual with different volumizers..??

It was at about 200 when I bought it.. whill I have to lower it to the values shown in the manual with different volumizers..??If you add the volumizer to bring the operating pressure down then YES you'll have to lower the minireg and at the same time increase the dwell until you are at the velocity you desire.

Then check for shootdown by letting it rip. If you get shootdown or drop off during firing really fast, you'll have to increase your dwell of up the minireg pressure.

BTW - 200psi is a pretty low pressure already. Did you have any problems running that low at 200psi?

have only tested like a full hopper or so and no no probz... but then again I didn´t had the chance to chrono,, probobly like low on the chron... dwell at 16
