help for svd WE fps inconsistency

[warlockuy]

hi
i need help
my svd problem fps variation.

my svd description upgrade

---Inner barrel Pdi 6.01 PSG-1 Long http://www.x-fire.org/etop/01.html item #648327
---Hephaestus Reinforced CNC Assembly for WE SVD GBB http://www.wgcshop.com/wgc2008/main/pro ... atid=&cat=
---Hop up , samless home made 0 pressure loss
---Nub Type H nub aluminium home made.
---Co2 system palmer boulder regulator.
--- scope POSP 6x42 1000m Rangefinder, SVD http://kalinkaoptics.com/posp-6x42-w-bl ... rsion.html
--- Bipode type harris

the Problem

the svd if I have 400 fps, varies very little, such as 10 fps.
in my country it is legal to play up to 600 fps.
in order to be always wanted to leave it at 550 fps.
this power has great variation
50 fps or more in some shots.
I was thinking how to fix it.
changing float valve

the NPAS is not really necessary apart no review of that leaves even more inconsistent.

the truth is not good for where to start, so I'm bothering you.

modify the floating valve spring?
larger change
hear ideas, all will be welcome help.


P.D : this is apart, had a tanaka and 600 fps variation was minimal between 5 and 10 fps.
I have to see how to do this with svd

co2 = no regular from svd

have to see how to fix it
not be very rather difficult

for me it is a matter of co2, is a matter of pressure, power
because if I leave it low pressure, not so variation.

we must find a solution
many tests and see how to fix it

Hello

I think you can't be regular as a bolt beacause this is Gbb-r.

Try to turn your SVD in HPA. I think this your better chance, but I won't do that on a ZAMAC made SVD

hi thanks for the message but does not think it's the solution.
tanaka is a gbb, only 5 to 10 fps variation using co2 600 fps.
one must look at how svd

as I said before, if I have to 450 fps with co2, varies very little.
the problem is when I give it more power.
certainly no solution, the issue is to find.
talves someone else already done this before and has any news.

Like other chargers WE, if you fill the feeder really thoroughly, there is not enough volume to vaporize the liquid gas in the first fire, resulting in a loss of power or erratic power 2 -3 first shots accompanied by a cloud of gas.

Hello very thanks
rubber is made ​​to order "I have a mold and control to do so and rubber percentage cilicona and caucho"
but not the problem, it has lost is much more than an original set
As I did the same test with pdi is same problem

hi thanks
is inconsistent from the first shot to the last shot.

the regulator is responsible not to let liquid co2 gas is equal anyway to put something up for me twice a prechamber of the charger, with a co2 output and variation well above the same

back to mensionar this
400 or 450 fps, no variation.
the problem only occurs when I put more power, 550 600 fps

is an issue there, that something is not ready for these powers.
I think that is something in the nozzle, or floating valve, spring or valve itself


very thanks

more information
removing the blowback
stable 15 fps variation strip
5 shoots Manual
650 fps

655
649

blowback is that all the gas is taken jajjaja.

the problem is flotanten valve. either the spring or the design of the valve
