the lines represent where honda placed the rev limiters from the factory.
Piston speed in a function of RPM and stroke only.
TO find out the piston speed --> Piston Speed = stroke in inches x RPM /6
I was trying to figure out what to set my tsx motor to so I made this graph to get an idea what kind of abuse are these honda OEM pistons supposed to take.... As you see.. even at 7100, the speed of the k24a piston is almost the same as teh k20a at 8000 RPM.. Just something to think about before deciding to see how much power your motor will make at 9000 rpm lol
