not that i know of, no it can't increase the rate of fire. as stated, the cyclic rate is dependent upon design of the action system.
as stated, a suppressor quiets down the cartridge the same way a muffler does on a vehicle. for cartridge to be fully suppressed it has to be sub-sonic ammo as well, below around 1100 FPS in muzzle velocity IIRC.
i saw some tests on some firearms years ago about whether a suppressed firearm lost muzzle velocity. in the tests they showed a very small decrease in muzzle velocity as a general rule vs. an unsuppressed firearm of the same type.
