[TheForge] Cylinder Size

[theforge@mailman.qth.net]

If you go with a larger bore on the cylinder you would need to also have the ports on the cylinder and and the valve be as large as possible.The trick is the amount of air flow you can get through the system as fast as you can get.You can have a large bore cylinder with big ports but if the valve ports are small and have a low cv rating then it will not cycle that fast.I have a 2" bore cylinder on my 25lbr with 3/8" ports on both the valve(which also has a high cv rate)and cylinder.it will do 240 beats /minute before that I had the same style valve with 1/4" ports and a lower cv and could only get 180 beats/minute
