| Critical RPM related loads vary with the SQUARE of RPM. So actually your statements about direct correlation are false. Your statement about the cliff after redline is somewhat accurate in that the square law relationship (which exists throughtout the RPM range) gets much worse when applied to larger numbers. BUT, this is not new info. The engineers, even in the 80s, were well aware of this and designed the car accordingly. Furthermore, we have a fleet of engines, as reported on this site for over two decades. RPM related failures are very uncommon. In fact, I would argue that the vast majority of engine failures that have been reported are not RPM related at all. Proper maintenance and oil changes are much more important. (High engine RPM didnt cause your turbo failure, or make your wiring harness old and crusty, or wear out your timing belt or water pump, or bung up your PCV or fail your injector or cause you to overheat...) In fact, looking at our sample, there are even surprisingly few lemons in the mix as well. It is a risk conversation, but your argument is long on hyperbole, short on both engineering physics and empirical evidence. Drive it like a grandpa if you like.
