Agreed, I should have said "at too low RPMs..." I doubt anything north of 2k in any gear would ever be an issue.

You hit the nail though regarding sound. I've got an aftermarket exhaust, and the sound is intoxicating above 3k, but it does have some drone in the 2's. So I've just kept it out of that range as a force of habit. But this thread has caused me to play around a bit and now I find myself gently cruising in 6th in the 60MPH range. The drone isn't oppressive as long as I don't ask too much of the car, and when I do, I drop a gear or three.

Maybe I'll even get another few MPGs.

I noticed the other day that in 6th at just above 2000rpm I was at 62-65 and motor seemed happy.

Anything below 2k rpms in our cars is asking for trouble. Sure it's easy to do and for some strange reason it feels perfectly ok to sit comfortably at 2k because of the huge torque on tap but this cars are meant to be driven above 2k in any gear especially 3rd onwards. If you lug your car you will prematurely screw your front diff, the cardan-shaft and the gearbox especially if the car is flashed and has even higher torque values lower down. I mentally retrained myself to keep my revs above 3k. Of course I then comfortably take it to onwards to the red line :-). Ps. If any of you recall I had my cardan-shaft and front diff replaced a while ago and complained to Porsche immediately about the rattling noise at low revs. They said that this is normal but I should avoid driving conditions whereby I can hear the noise. Ha ha ha. That answered my question - read; engineering weak point! If you love your transmission parts keep your rpms @ 3k and above for most of your driving.

I had no lugging but will take your advice in mind.

Where is that written?

I don't ever have that noise.

I don't think that is a valid blanket statement.

...and i was off by about 1 k rpm. 5th @ 62/65mph is roughly 3k rpm. ha oh the minutia of it all

Personal preference but I try to never have the rpms below 2k, and usually closer to three. I rarely use 6th gear

This anecdote hardly qualifies as evidence and seems to be a pretty dodgy explanation from an engineering standpoint.

perhaps try not to make it appear that your opinions are facts?

+1...of course you might have to disregard most of the posts on these forums as very few have actual data to support statements made...LOL

"02996ttx50

i agree, but would up the ante. disregard ALL the posts on here as they are all conjecture and no one has any experience with these cars. why, I've never even had a 911 myself LOL

wross996tt

Not quite...I know guys like Kevin, jpflip, Loren to name a few actually DO know what they speak of. Some on the other hand...LOL

It seems that each gear 4th and higher is at about 2,000 RPMs when I'm at 40mph in 4th, 50mph in fifth, and 60mph in 6th (speedometer reading). I generally use that as a rule of thumb when cruising as my minimum speed in those 3 gears. I've found this to be true in my 6-speed A4 and 6-speed S4 I had previously. If anything more than mild throttle is needed, I downshift.

Similar to what others have experienced, my aftermarket exhaust gets the most drone in the 2,200 to 2,800 rpm range so I try to avoid that. Luckily the freeway speed limits here are 70 for the most part so I can cruise in 6th at 77mph actual (80 speedometer) at around 3,000rpm with little to no drone.

I don't think driving at 2,000rpm in this car can be considered "lugging it" unless you're flooring it in a high gear, are going up a steep incline, or a combination of both. My engine seems happy at 2,000rpm and low load with no strange vibrations etc. associated with lugging a car. One downside I can think of though is carbon buildup, so some wide open throttle pulls in high RPM's from time to time are recommended

I would down shift to accelerate at a good pace but cruising at 2000rpm and above in 6th is not going to hurt anything= just my opinion.

breakfast

definitely wont.

I agree the engine is not lugging at 2k in 6th. Car should be doing 60mph in 6th gear @ 2k.
