Need beta testers for a mag efficiency upgrade.

Looks like these will cost $12 to $15, shipped for the beta run with the requirement of feedback. Meaning the buyer needs to have purchased the red power tube oring and are prepared to pay attention to there air to ball consumption pretty closely as they play. Then report back those numbers and any tuning issues they had.

I need feedback so I cam make any needed changes before I have a bunch of these made.

These are the prototypes



There are 5 spots for the Classic and 5 for the X-valve. So post if you want to pick one up and help with the testing process. If any changes are needed the people who get a beta version will get the improved version free of charge.

Classic Valve(I will do a video but you may need to have the power tube removed by a pro on this valve)
1. chadders
2.
3.
5.
5.


X-valve (I will do a video on how to remove this valve's power tube.)
1. chadders
2. james
3. M600
4.
5.


Locations for the red power tube oring and so you know what it looks like. Once removed you can open and close the power tube area many times without damaging the oring, but the first time destroys it usually.

Xvalve


Classic

I'd love to help, but I'm waiting to see how this works so I can judge if I want to invest in another mag... I wound up parting mine because it got absolutely horrid efficiency...

I'll test an X-Valve one. But what exactly does this do? Increase airflow? I may have some other guys in Louisville that will test them also.

The opposite actually, they devolumize the dump chamber, requiring you to turn the reg pressure up higher to attain velocity but also giving better efficiency.

It does both actually. The insert is tapered for better flow and it de-volumizes the shot chamber making you turn up the pressure.

james- got you on the list.

I have a 1200psi ninja reg, So I will lose the rt affect on my x-valve with this?

Not sure yet. That is one of the things I need to find out, but I would think it would reduce it a little.

The RT effect will be diminished. The reason given for the RT effect is heating of the incoming air due to rapid recharging. I do not believe this is the correct cause. When we did a load of experiments regarding on/off pin head versus shaft diameter, we discovered that the more area on the head, the more pronounced the RT effect. (The reason the ULT is less reactive is directly related.) We also noted that the higher the input pressure and the lower the chamber pressure, the more reactive the trigger became. I believe that the pressure differential between input pressure and chamber pressure has as much to do with the RT as the surface area of the head of the on/off pin.

Good luck with your experiment! I hope this will yield some useful information.

One more thing. Check the velocity using the RT method, described by Tom Kaye. Hold the trigger and then release, pull and hold as fast as possible, in addition to chronoing normally. This will allow you to see if there is an issue being caused by the change in the chamber volume.
