It's not mine, but here's a happy Porsche:
In Germany they are driven this way for hours with no ill effects!

The same could be said for learning how to spell and write correctly.

Although carbon build-up isn't good, I suspect another reason (perhaps the primary reason) for the advice to keep the revs up was the fact that all of the early Porsches were air cooled. Keeping the revs up meant airflow--lugging an aircooled engine is the fastest way to kill it.

It was originally mostly a spark plug fouling issue. Before CD (in 69?) fouling was a major problem. Could happen in minutes, especially in traffic. Some people even put hotter plugs in for city driving and switched to cold ones for open road/track. We all tried to use Amoco Super Premium because it was the only lead free gas.
Low rpm carbon deposits can form around the top of the cylinder and the results can be disastrous after years of build-up when a trip to redline "stretches" the rod & piston into collision with the nasty carbon.

There are also mechanical (inertial) reasons to keep load down at low rpm. In general it's a good idea to keep in the higher rev ranges if load is going to be high. This is generally when you feel the need to "floor it".

How about adding an automatic spell checker for this board?

I wonder if that 140 is with the cruise control engaged or just "ready" as seen by the idiot light...

That 140 is a little odd. Everything is 140, the odometer is 140140, the tripometer is 140, and the speed is 140. I'm thinking a little photoshop went into that.

Good point.
Is the rpm vs. speed even right, I wonder?

ps
If it's a photoshopped image, it was done pretty well. I dropped the picture into PS and played with the color channels, which usually reveals fakes quite quickly.
Probably just a guy that like to take pictures at unique moments

Well, I've found the high revs thing to be pretty much true. When my idle stumbles around a little bit, a good run up to higher RPMs usually helps (Of course, done when the engine is up to operating temperature).
So I'd agree that running the engine up to higher RPMs is good... I would not say:
"Keep it above 4000rpm"
I doubt it's a good idea to keep your engine running over 4000RPM AT ALL TIMES. Even when properly warmed up. Not that I think the engine will grenade, I just think it's not necessary.
So, I'd say "it's a good idea to push the engine above 4000rpm relatively frequently in order to burn off carbon deposits"
BTW, the process of running the piss out of the engine in order to burn off carbon deposits is sometimes called "an Italian Tune-up". Or so I've heard it called.

Yes the cruise was on according to the owner.

He's been planning and doing this since 100,000 miles:
BTW he has to add no oil between changes and he still has the original clutch!!!
