Pump up the volume (fork/air can content)

Anyone had a go with this tackle??

from these fellas: http://rollonthrottle.com/forkace.html

bigger volume more progressive travel? I can follow the thinking, I’d be interested to know if anyone’s tried it?

I guess if you have problems with a spring rate that is too rising, then it could be useful I guess.
But surely that just means you have a poorly designed fork/frame.

same idea as a high volume air can?

I understand that it increases the air volume that is being compressed, now not being all that clued up on the nature of compressed air and the variables of cylinder volume, I’m assuming that the bigger the cylinder the smoother the compression?

R_R, I think so?
