The only guy that has provided any real data with real numbers from his record book is Matt MCW, everyone else is talking from their A$$. 40% 50% better production, come on, way to many variables here to just say my saws faster so I get more wood on the ground.
When most guys first start running saws like Hillbilly they don't know anything about tuning chains and so on, this was very obvious in Hillbilly's first vid of his EC 372 it was turning what 10,000 rpm's it was so rich. My point, when most start running ported saws they start paying attention to tune, chain and so on.:msp_rolleyes:
