I got that guidance from the Porsche experience crew and from a Porsche lemans engineer himself, who I trust far more than the manual
No WOT neither baby load but try to keep it on medium loads

with a similar rpm guidance to the one posted above. A blanket "don't go beyond 7000rpm until 1500km and then pedal to the metal" is absurd ...but hey that is what the manual says...

Of course you and your gut feeling can to whatever you please ...

 

Common sense rules. If an engine is not up to operating temperature, don't stress it, don't do anything stupid with it.

Moving parts are designed with a specific operating temperature in mind, be it engine or gearbox, when new the fitment might be tighter hence why there is a 'break in' period. Modern parts are more about 'seating the seal', than actually wearing down metal to fitment. Honestly, after 15-20hrs of running, everything is seated and sealed properly.

Every now and then, we read about idiots blowing up an engine even after 1000 miles.

In contrast to that, Porsche supply their European driving schools with brand new cars each year, they don't have time to drive 1500km 'break in' miles on 30-40 cars. But they do make sure all the cars are up to temperature before students get in and abuse them. Mechanical failure rate of those school cars are almost nil. They have a higher rate of suffering body damage than engine failure. These school cars will be off to the secondary market after finishing the school season.

 

Operating temperature is common sense for all the engine life, not just for break-in

 

The first 300 mi below 5k then add 500 rpm every 100 mi is roughly what AP, head of porsche GT, has been quoted saying in how he breaks in his engines. (Seems like there is variance, 500 mi no more than 5k but also recently 300 mi no more than 3.5k rpm or so) The carwow guy did a video on breaking in his 992 gt3rs, following AP's suggestions.

 

Once again, unlike you, I am not comparing to other Porsches. It is a trait of German cars in general to have that planted, tied down feel -- likely due to design for ordinary folks driving on the autobahn. Does feel good and safe on the freeway. But does take away a bit of aliveness at less 8/10. It's a design tradeoff. I am not telling you anything that lots of driving enthusiasts do not already know. Go drive a 458, or a Miata. Porsches are great cars. But not the be all and end all for those of us who love cars. We are enthusiasts, not cultists.

I do have mags. I said "slightly" and "a bit." Talking on the margins here. Not dumping on your treasured Porsche. No need to get offended.

Stop calling other people's opinions rubbish. You are not making yourself look smart.

 

You'd be surprised how many out there don't have the simplest of common sense.

 

Yes, and AP himself has reportedly issued different guidance. I'm not relying on my own gut feeling, the OFFICIAL guidance from the manufacturer is what's in the owner's manual, and that's what I'm going with.

 

Second day of ownership, drove the car another 50 miles today.

Going from memory, without doing a back to back comparison, today the 4RS felt to me like a mid-engine 992 GT3 with a louder and more complex soundtrack, more aggressive PDK shifting, and a cozier 991-like cabin. Aside from the sound and shifting, I think the two cars are more alike than they're different. But they're differentiated enough that they don't compete with each other too much, and someone could justify owning both (as I have). I don't think either car is generally superior to the other, I put them right on the same tier.

I didn't do any WOT today, but the 4RS felt plenty fast to me.

 

In order to help those who are common-sense challenged, I think the electronic rev limit is set to 7k rpm (down from 9k) prior to the oil being warm. Although 7k is still higher than I would hit with a cold engine...

 

I would not do that either lol. but WOT means full torque on a new engine ! As you cannot use the revs esp below 300 miles, you are asking ALOT of the engine on low revs on WOT ! .

build up the revs, never lug the engine and change gear a lot. Increase revs every 100 miles after the 1st 300miles. AP's told every one how to do it, forget the manual that's different in every country.

 

Not really I often think 85% of the population are VERY stupid ;-) every day I am gob smacked how stupid most people actually are.

 

Drove the 992 TTS (PASM) to work today. Ride quality of the 4RS is definitely better than the 992 TTS. The only thing which might keep the 4RS from the being a daily driver is the sound level.

 

Wow, 4rs has better ride quality than the ultimate DD 911? Wouldn't have guessed that. Can u theorize on why that might be?

 

Yeah my 992 TT was brutal on anything but the smoothest of roads. Even with comfort setting on the air pressures.

Snow tires were a bit better, but still harsh.

 

992 TTS has the option of Sport PASM suspension, which is 10 mm lower and presumably has stiffer springs. Tuning of the car was done by the people Weissach who do the GT cars. and I think they wanted to get serious performance out of a car that's considerably heavier than a GT3.

I haven't driven the 992 TTS with the regular suspension, so can't comment on that.

I had a 991.2 TTS and that definitely had the range of going from comfortable DD to track weapon.
