they dropped the redline because the bigger displacement motor loses power sooner. not because of any excess mechanical stress. i think the only thing one would have to do to rev an F22 to 9k would be to swap the valvetrain (i think). but again, the power loss would probably make it slower than just shifting back to 6k.

i think one reason for the lower redline is bc of an increased stoke. they increased the displacement by increasing the stroke and not the bore. this results in higher piston speeds. they wanted to keep the piston speeds in check so they lowered the redline.

correct me if im wrong
