Tuning 90CC+ plenums

[anorphirith]

Hi,
Do we have a list of rifles with plenums larger than ~70cc ?
It's so hard to find infos online
that's what I have so far:
M3 impact is 72cc
Dynamic goes up to 156cc
RTI prophet 70cc

 

[Raider03]

FX Maverick 89cc

 

[EPG]

FX Dreamline Power Pup has an 80cc plenum.

 

[JungleShooter]

The RTI Prophet 2 (Performance and Regular models) come with 70cc plenum.
However, an additional 22cc plenum can be installed very easily (around $40).
= 92cc

And, I think (please correct me), it has not one but two seats for those plenums — so add another 22cc for a total of 114cc.

Hello guys, I have a question: if I add a power plenum on a Priest2 .25 with a 60cm barrel how many fps I increase with 22 cc extra of air ? Or just I have same speed but more shot count ? If someone already tested and let me know thank you really !

Karma Red Panda Bench = 250cc
Karma Red Panda PRS = 125cc

Are these numbers provided by the manufacturer, or are you actually measuring them?
If your actually measuring them yourself, please explain your process.

AGT Vulcan 3 in big plenum mode, have,,,, OMG a lot.
My 700 mm Epic airguns Two ( tube version ) have 121 CC plenum,the 550 mm barrel version have 101 CC plenum and the compact with 300 mm barrel have 70 CC.
The bottle versions no matter the barrel length / caliber just 70 CC plenum

You also need a valve system that allow for that plenum to be dumped into the barrel.

I could probably easy extend my plenum or for that matter tank section with 70 CC more, i got about 100 MM from the end of the air pipe to the end of the barrel.
Not something i will pursue though as i shoot tethered all the time.
