Would a V2 M16-a1/VN mechbox be more quiet than a V2 M16-a2 mechbox?

[Oborous]

Does anyone have any actual experience with the spring area of a V2 mechbox being sealed in comparision to a 'normal' mechbox? All things being equal...

See:
Sealed
Unsealed
(Used the Energy mechboxes for example because Redwolf did actually take pictures of the two to show the differences)

I'm trying to figure out if the seal would contain the sound better, or if trying to suck the air in would cause a whistle effect?

I doubt you would be able to even notice a difference. From a "Technical" standpoint, more material = less noise...

The noise comes from;

Motor spinning
Piston on cylinder head
Gears turning

If you want silence;

TM motor that's comm lathed by someone that knows what they're doing
Helical gears that are shimmed PERFECTLY, Debatable on the mixture of bushing/bearing I find bushings on the bevel, sector and bearings on the spur gear to be the quietest
Sorbothane pad on your cylinder head, and a MASK white POM piston head w/ sobo tablet
MOSFET with active breaking / Soft start to kill even more motor nice
Silencer that's god a very good composition of foam inside it... (like this MAGPUL one that I just so happen to have here :P )

where'd you get that suppressor?

Magic :P

It was an extremely limited run... I bought one LOOONG time ago.. I was gonna use it for my M4 project... but that M4 project turned into an SVD.

I'm just trying to figure out if that mechbox would actually silence or change the pitch (you're still sucking a fair amount of air for the piston... where would that air 'come' from for the sealed mechbox).

Please tell me more about the lathed motor... I haven't heard that one before.

There are some other tricks that I know of (but most of them are small returns on the silence factor, mainly done for other reasons):
Polishing the interal mechbox rails for a smoother ride
Bearing spring guide for not torquing the piston
heavy weight oil between the inner and outer barrels.
some sort of ear plug or similar instead of the hopup spring, so they hopup is consistently against the mechbox
If mechbox/body allows, good UMWPE tape between the mechbox and body to dampen the transfer of mechbox noise to the metal body. (This is similar to foaming a sniper rifle)

Any other little tricks?

I think he's talking about making your own motor shaft cover (tower) like the angel product.

Their is technical details on it here:

No he means actually getting your motor tuned properly by an RC hobbyist with an RC motor lathe. Also having a few other things done to it...
It decreases the amount of amperage required by the motor (increasing battery life), and also reduces noise by a little bit.
