Keep her above 4000rpm and she'll thank you for it every day.

The analogy is still apt. At what RPM do these guys make all that HP? Well, up near red line.

Read the title of the thread again. The contention here is that running your box up at very high RPMs is GOOD FOR THE CAR!

That simply can't be substantiated by good physics or engineering.

It might be good for the driver (it is very much fun) but I simply don't like sloppy thinking.

I am not suggesting anyone drive around town and lug the motor nor not run the car at whatever RPM they want.

I am suggesting that they get real. Running the car at 5000 RPM plus is not doing your engine a world of good. It is not a muscle, it does NOT get stronger with use.
