Ring aficionados like Larry Cable here on RL say that anything under about 8 minutes BTG is a very decent time for a GT3! I think you have to credit the driver.
yep 8 mins in traffic BtoG is a good time ... anything 8 and under is going for it...

definitely 997.1 GT3 territory ...

I dont think that was a BtoG, I think it was a full flying lap of the ring, which is about another 1.7km longer (essentially the front straight) and about +25secs
difference from a BtoG time... usually done with no traffic, a professional driver
and a factory team to tune the car etc...

7:40, but you'd need to understand German, presumably they wouldn't quote a BTG time for marketing purposes, and that's also presumably on "normal" tires since the 991S is not fitted with Sport Cups or other and the P-Zero and PS2 tires are a lot slower apex speeds than MPSC. Apples to apples? 991S on Sport Cups vs 997 II GT3 on Sport Cups ... manual box to manual box ... I don't think anyone's denying the point to point performance of the 991, it's still just a matter of "do you want to?"

I loved the sound of my base 997.2 (3.6)! I ordered a 991s this time since i wasnt sure on the 3.4 in the base model. I hope it sounds as good and revs as nice as that 3.4 in that video...

totally! AFIAK all the manufacturer times are full flying laps of the ring, its not possible to do these during touristfahren so BtoG is as good as it gets unless
you attend a private day like Manthey or RMA ... the difference between BtoG and full lap is essentially the front straight from the gantry to the bridge at
antoniusbuche/tiergarten, which is a distance of about 1.7km, this is good for
around +20-25secs for a BtoG vs full lap...

I believe the 7:40 for the 991S is about the same as that for the 7.2 GT3...

I forget what the RS 4.0 was ...

I *assume* but do not know that these times occur on the stock tyres etc ...

no, not really, there are "plenty" of other cars faster than the current flock of GT3's around the ring ... and I dont want to own any of them either...

it would be interesting to see how fast the 991S + powerkit + aero will lap the ring, that will probably set the baseline for the forthcoming GT3...

Here's a pretty realistic recording of the engine soundtrack.

Default 991 3.4 PDK 7.46 BTG

Hi all,

the car and video referred to is mine. Now I managed a 7.46 BTG lap, here is the video:

Have sports exhaust, PDK, Sport Chrono, sports suspention SPASM(no PDCC), Torque Vectoring diff, 20" wheels.

Incredible car when pushing it hard!

Here is a video from around the track, me driving the shiny silver carand also a Carrera S of a friend of mine, matt silver color.

Awesome driving, Dag! Do you have a lap time for the full Nordschleife or alternatively, do you have a BTG time driving a Carrera S? I'm trying to see how much slower the base is around the ring, in an apples-to-apples comparison. Anyways, looks like awesome fun, congrats!!

Dag-this is so cool! If I understand this correctly-the 991s did this is 7:40 and you in 7:46? Also, what is BTG? Would love to get your thoughts on the s and non-s. Cheers.

Default base Carrera

BTG lap, possible to measure for normal people during tourist driving. (long straight is then closed)
Full lap, hardly used at all. 20832 meters
Sport Auto lap, the standard used by Porsche, Nissan, Chevrolet and Sport Auto Magazine.

8 minutes full lap = 7.54 Sport Auto lap
6 seconds shorter because you dont measure the short straight passing the old pit area.
BTG is appr. 25 seconds shorter than full lap, 19 seconds shorter than Sport Auto lap.
7.54 Sport Auto lap = 7.35 BTG

BTG=Bridge to gauntry. You start the clock under the bridge at the end of the straight, stops it under a big sign (gauntry) at the beginning of the straight.

BUT, when Porsche or Sport Auto do their tests they fly pass the bridge doing 250-270. As a tourist you have around 170-190 there, so at least 3 second advantage for the pros.

I did a 7.46.
Traffic around 10 seconds penalty (may look like 3 to you, but its not)
So 7.36 plus 19 = 7.55
A pro driver would easily beat me 10-15 seconds. Pro driver Marco Seefried took my car for a lap, I took of 4 seconds after learning some tricks :-) Could probably take a couple more easily. Having a passanger as I had may also slow me down.
So between 7.40-7.45 would be the base Carrera time, pro driver and clear track, standard Pirelli tires. Thats not much slower than the S. It is kind of confirmed by the 1.15 seconds time difference at Balacco, almost 3 minutes long track. (S vs base Carrera tested by Italian Magazine Auto)

After 5 hours full speed at the autobahn racing an S and a Ferrari California, three cars seemed equal in speed.

The S is faster and stronger, but be aware +50 horsepower is not much.

In Norway the price difference between base and S when fully speced is 30.000 USD, so base for me. In other countries its a lot less, so Carrera S :-)

The base Carrera has a harder more racy sound inside the cabin actually.

Test both if you wonder what you want.

PDCC, my friend has it and it SUCKS at the Ring. Car is twithing, Porsche test drivers confirm this. Stay away from it is my advice. My friend is selling his S and buying one with SPASM, like I have. It works incredibly good. The poor bastard also have a GT2RS, did a 7.16,9 lap same day as my 7.46.
