Very much in concordance with Ed.
The industry standard maximum average piston speed is 4000 ft/sec. Beyond this maximum average piston speed, the bottom end is likely to be suspect unless there have been significant modifications.
The engineers that designed the engine will have done this relatively simple calculation and then factor in a range of limitations in the engine so that fools who think 5Ms are safe at 9500 rpm don't ever actually get to take them there. Thank goodness for the rev limiter.
One then has to ask what is the "real life" redline. There may be little point in taking a motor to its theoretical redline as the power developed at that maximum engine speed may be significantly less than peak power. It only results in "wear and tear" and decreased engine lifespan.
Most people who claim their engine still feels like it is making power a some ungodly engine speed would be shocked if it were placed on a dyno and objectively tested.
