Is it wrong of me to motor in 6th at 1.6K rpm and admire my motor sound...?

You are correct, rome. In fact I find if I don't run out fist gear there is too big a drop off at second to keep you in the power.
And as far as sounding better at higher RPMS-- Put the ole 993 on a Dyno and give a listen. It - is - awesome. Despite all the meaningful data, far and away the best memory I have of that day.

901-- I try to drive mine like you do and keep the revs at least 3000 in each gear, or more. It's true that is the way these engines are designed to work (as compared to a garden variety automatic transmission which is always upshifting to stay at 2000 rpms).
It is interesting-- I also have a Cayenne S (tiptronic), and when you switch off the PSM it becomes a whole different animal by changing the shift patterns so that the car runs at least in the 3000-4000 rpm range. It is really instructive in terms of showing how Porsche engines are designed to perform.

Consider the engineer's statements in the first minute or so of this exceptional (albeit lengthy) 993 video produced by Porsche: http://www.coochas.com/porsche/Resou...0Evolution.wmv
These 993 engine were designed to run at top speed all day long.
5000 RPMs is well below the redline and well within this car's sweet spot.
I certainly don't run my car nearly that hard on a consistent basis-- who can given speed limits etc.-- but it is built to do it.

They rationalize this by saying the car was "built to do it". Maybe not you, but plenty that do.
I understand the engineers' "intent", but I also understand: these cars are getting long in the tooth. My 964 came out of the factory over 16 years ago. Even the newest 993's are almost 10 years old. I can't run like I used to, and I don't need to find out if old car can ($$$).

Would it be a "true" gauge of proper shift style to observe a 993 automatic? That is, does the automatic trans follow the same shift points as are recommended on this thread? As I have a manual trans, I'll assume the autos were before today's styles that "adapt" to your driving style.

I'm not telling which gear

Very informative thread, thanks to all. Call me stupid but I thought that while steady state cruising a good range was sort of 2500-3000 rpm. Well now I know I was wrong! I guess I'm used to my 66 Vette and my Land Rovers (in which you're lucky to ever see 4000 rpm , and at that point it sounds like the gerbils under the hood are committing hari kari). I will now spend the rest of my 993 life above 3K.
I also didn't know that a "steady state" warm up (i.e. warming up at idle) was bad. I actually thought this was a good thing to get everything warmed up before putting and load on the drivetrain. Why is a steady state warm up bad? Is this peculiar to the 993 and the SAI issues?
As a new 993 owner, one thing I have found is that first gear seems awfully short for a street car. Maybe it's just me, but I wish it were a bit taller. I feel like I'm always winding way up in first to get anywhere from a stoplight. To me it seems the car would be a better driver with a taller first gear. Am I crazy? If so, why did Porsche design this tranny with such a short first gear?
