driving below 2800 RPM = trouble?

Einstein used to like to do thought experiments. Lets do one with this.

Driver A sets out for cross counrtry trip, 3500 miles on the Interstates. To make this fun, he simply gets in, drives at 75 MPH and about 3000 RPMs.

Now, Driver B is sure that this low RPM crap is for the birds. He knows his car should be meant to be driven faster, at higher RPMs.. Anything less that 6500 RPMs will ruin his race intended Boxster, even though it is a stock Box. Hey, Porsche is a racing company right?

So, off he goes. Now, in this experment, there are NO speed limits, so he can run at 6500 RPM the whole way. He can use any gear he wants, so he choose to cruise in sixth grear, which maybe nets him about 140 MPH????

Anyway, off they go.

Now, who gets there first? Well, if both engines hold up, clearly driver B if he choose to go faster than 75 MPH.

Now, whose motor was STRESSED more? which car's oil ran hotter during the entire trip? Which motor would have worn more, even if we can't measure it right now? Which oil is still fresh as a daisy after 3500 miles.

What do you think?

Porsches are made to be driven at 6500 rpms all day long. And they do so in Germany everyday of the year.

The car will last longer than most of us have left, so enjoy it.

Actually I never said they woudn't. The assertion made here is that they will NOT drive all day long at say 3000 RPMs and that the 6500 level results in less engine wear and risk of IMS implosion.
