K-11 is a rotor design ie: K8, K9, K11 it comes in many different blowers. Its not a blower.

A PSI will not go out of time, I beleive it has better engineering then the kobelco. It is heavier. Boost number wise the PSI is higher "55" but depends on what motor as well. Do not buy any of the older design style rotors i.e k-8 or k-9 had many issues with them coming apart.

Both are good blowers. But to wake them up the mods help. Just need to watch rotor speed so they do not go super sonic.
