Rate of fire with a standard AIR

[Punisher]

I've enjoyed messing with Mags on occasion over the years, owned a couple of my own, however I've never heard a definitive limit when it comes to recharge rate vs. rate of fire of a standard Mag AIR valve.
When I built the first PneuMag, while I couldn't shoot it fast enough to see any drop off, nor could the owner, It was recommended by various sources that a RetroValve would be needed due to the high rate of fire it was capable of.
I've been working on the second generation of the PneuMag, as well as my own version of the EMag. Again the question comes up:
Just how fast can it shoot before shootdown or any other bad thing starts to occur? Does anyone have a solid number, maybe a spread across various velocities/pressure settings?
How about an insider's point of view?

if you look on the halo site there is a vid of a stock mag valve shooting 16 bps full auto with a hyper frame. No drop off could be seen.

Gecko, that was an Emag.

Punisher, first off, its great to see you on the board. Without a Retrovalve, a 'Mag can handle 8-9 BPS without drop off, anything beyond that requires the Retrovalve which can do "26" with out drop off. No drop off isn't the only strong point of a Retrovalve, it makes a wicked trigger as well. Can't what do see what you come up with. :)

no there is one with a hyperframed powerfeed automag.

The gun is a '93 Automag with a Hyperframe on full auto set to 16 BPS.

I see that, thanks. They have the Emag at 15,17, and 18, I thought you were reffering to those. My bad. :o

That sure rips with a hyperframe though

The Classic A.I.R. valve can do better than 16bps without shootdown.

Here's proof; 1993 Classic valve with hyperframe, fed by HALO:
