Guys,

I find that the 997 transmission and gearing are very well matched and permissive. I find that I like shifting the car at a bit over 3000 rpms but not sure when driving in the city, which is the right gear for the speed when following the city speed limit ???

Am I wrong to think that steady 3000rpms is about the right rpm cruising speed where the rpms are just right without either be over-revving or bogging the engine down???

What's your experience ???

I certainly like to keep the engine above 1000 and 1500rpms, it just feels like it's trying to hard to pull a high gear. I try to keep it no less than 2000rpm in the day to day. It seems to me that the engine is happy at 3000-4000rpm, circulating plenty of oil and coolant around at that engine speed, managing the heat.

I have just few rules:
I don't lug the engine - ever!
No higher rpm:s than 3.000 until engine oil is fully warmed up.

I agree that engine is happy around 3.000 rpm. Works fine to daily drive 2000-4000 rpm.

I usually also rev it out fully on a few gears every time I drive (provides that engine is warm) Partly because it's a pleasure to do it but also I think it keeps engine more free from problems. If cause also those occasional spirited drives where the rpm never stays below 3000-3500

These engines are built for high rpm:s. Low rpm is more damaging than high. As mentioned above: oil pressure is not that high when you lug the engine so there will be risk for poor lubrication.

Sounds like you have a healthy overall driving style.

Yes, 3000 RPM seems to be the sweet spot on the American roads (mostly in city and highways).

Never below 2,000 and 2,600-4,200 in normal driving with some runs up past 6k when it makes sense. You can hear the variocam plus change the exhaust note at around 3,800.

Ok thanks. I will continue driving it the way I do.

Under 4k until oil reaches 150+ as per Porsche manual. After that I enjoy the car the way it was meant to be driven. I don't abuse it but it does see a fair share of 6k+ pulls.

Once it's warmed up, I like keeping my Turbo around 3000. Not just for the more immediate power, but because I have an exhaust and it just makes the experience feel more exciting and racy. Even on the highway, I'll usually keep it in 5th instead of 6th unless I know I'm just going to be doing long distance at a constant speed - 6th becomes my "meh, whatever, this is just A-B" highway gear.

This and this^^^
You do need to get it up in revs from time to time. They were designed for it and that is also where the real fun factor is.

I had some jackass tell my wife that her GT4 "does not need to be warmed up. It is a GT car: these cars are fine to run hard cold". This was at a DE event!

Never mind this is NOT a GT motorsport engine, but a standard 9A1 with some tweaks, but even if it were, would any of us go hammer a cold engine? A GT3 warms up quickly due to the heat produced in the engine, but even that car needs a nice 5-10 minutes, depending on ambient temp.
