What you want is the cylinder volume to match the barrel volume. To much and you will get excessive noise, but to little and you wont get the desired shot.
When you say noise
, do you mean like a very loud pop sound?
From my search, nobody ever shared figures regarding the cylinder volume of a Laylax Type96 Cylinder.
I measured the amount of cylinder volume available in front of the piston head once it was cocked (CYL):
Volume (v)= (Length) x (Radius^2) x (Pi)
v= (90mm) x (10mm^2) x (Pi)
mm cubed (CYL)
Now the calculation of a 6.01mm barrel with 499mm length (IB):
v= (499) x (3.005^2) x (Pi)
mm cubed (IB)
So the barrel length ratio:
= (28,274.3339) / (14,155.9614)
This part is slightly off topic
Someone once mentioned that 1.2-1.4 was a good ratio.
I believe that the same person also mentioned that FPS and BB Weight affected the "ideal" ratio desired.
^^^ I haven't tested this, but assuming others agree and he was correct, then what actually matters is the JOULES of force being shot out of the inner barrel.
Therefore a higher joule amount would require a greater CYL/IB ratio.
Going back on topic, what's an ideal ratio from your experiences?
In conclusion, Airsoft needs more decisive evidence :doh:.
Note: My measurements done with a millimeter tape measure.
I feel like I may have measured the cylinder volume wrong so if someone would like to correct me in any way please do so.
