I cant believe that the GT3 had such a bad Result in the Supertest...

Hockenheim: 1:09,6 Min
Nordschleife: 7:32 Min

Both laptimes are slower than the ones of the RS 4.0 ...


To make it even worse: The Turbo S is also in the journal and it posted a 1:08.7 Min laptime around Hockenheim ...

I am kind of speechless and hyper-dissapointed ...


The car used the Michelin PS Cup 2 tyres and the Turbo S the Dunlop Sport Maxx Race, maybe the Michelins aren't all that good? I mean, the laptime against the McLaren was also driven on the Dunlop tire... The max. G result was also 0,05G down on the old RS 4.0, which used the Michelin Pilot Sport Cup + ... And the car suspension setup was only with -1,5° of camber (front and rear) ... but still...

It also needs to be said, that the car had an error when the magazine tried to dyno it (and needed to get back to Porsche), so maybe it was also a tad down on power...

But still, they say the car would be awesome at 95% speed but very difficult to drive on the limit due to the RWS ... they even said that the system (RWS) works better on the Turbo S as it ain't doing these difficulties when pushing at the limit ...

All I can say... I am DISAPPOINTED....

Dear CaymanR-racer, don't you exaggerate a bit with your disappointment ? To gain some seconds especially on Nordschleife everything must be 100% functionning .....there were former comparisons where the GT3 was more quick on Nordschleife compared to the Turbo S......however the Turbo S had normal Pirelli P Zero tyres. With all enthusiasm to the GT3 ( I ordered also one) we need to be clear that the Turbo S has much more power and the same electronic support systems as the GT3 (RWS etc)........so on straights the Turbo is more quick, the Gt3 more agile in corners..........bottom line they are on the same level and will always differ in the tests......
Did you ever drive on Hockenheim and especially Nordschleife ? With all respect, please go there and beat the mentioned lap times....😜. Cheers

Looks like I owe Porsche Collector a bottle of wine!!!

CaymanR-Racer

Yes, I drove there already on both circuits... and I also orderd a 991 GT3...

To see my Nordschleife laps you can have a look here -> https://rennlist.com/forums/987-981-...l#post10838382
Actually, my theoretical best complete lap is 10 seconds faster than the Sportauto laptime of the Cayman R... but never mind xD


And yes, I am disappointed... The Turbo S is nearly a second quicker and the Carrera S was only 0,8 Sec. slower... and the Carrera S wasnt on semi-slicks and only has 400hp etc ...

and Hockenheim is a very technical circuit, hence hp doesnt make such a big difference.. Thats why the Cayman R was faster than the 997 Carrera GTS etc... and hence it is very surprising that even on that circuit the Turbo, with all the extra weight etc, is that much faster... If it will do nearly as well on the Nordschleife, then its time will be easily below 7:30 ....

Maybe I expected too much from the new GT3... I mean, I hoped and thought it would be quicker than the RS 4.0 ...

Maybe they had a broken 991 GT3 as they say. Maybe it was the piston it put through the block twhen that journo drove it hat made it down on power?

CaymanR-Racer

They said it was an ECU problem and Porsche fixed it after the dyno test ... and I compared the topspeeds on the straights of the Nordschleife with the RS 4.0 and they are nearly identical, so I doubt it was down on power.. the cornering speeds are lower though, at some corners nearly 10 km/h

Macca

Seems very odd given Uwes lap of the Ring in the car (and he has driven 3.8 & 4.0 GT3 there). Also the factory drivers and the engineers (I know one of) all claimed it was definitely quicker than the 4.0. Oh well. Maybe it was wishful thinking to imagine it could out perfrom the 185K Euro 4.0RS. Out of interest how many HP did it dyno?

CaymanR-Racer

They couldnt finish it due to the error... the car went into limp mode when revved above 7500rpm

At 7500rpm it had 457hp...

But topspeed on the nordschleife were as follows (compared to the RS 4.0)

Döttinger Höhe: 278km/h vs (278km/h)
Schwedenkreuz: 259 km/h vs (261km/h)
Fuchsröhre: 245 km/h vs (243km/h)
Kesselchen: 241 km/h vs (241km/h)

Macca

Mmmm. It make peak power at 8250 rpm. At 7500 rpm according to the factory power chart it will be making 333km or 453 bhp so I guess this is in line with what Porsche publish. However the comments re RWS is very odd. Perhaps there is an issue here. 991TTS had up to 3 degrees toe in adjustment on RWS vs GT3 1.5 degrees. I do expect the 991TTS to be faster on Sport Maax R compound on the Ring as these are the equivalent to MPSC2. I guess the results are in line with general expectations as guys who know SportAuto test were confident the time would be 7.32-7.34 even though Porsche Posted lower with their factory drivers...I guess the surprise was the short course track...

CaymanR-Racer

Maybe its really the MSPC2 thats so weak... I mean it got a tread wear rating of 180 ...

Would at least explain why the max G of the RS 4.0 was higher and why the Turbo S with the dunlops (TWI = 80) was quicker... I mean, the turbo pulled nearly in every corner 0,1G higher than the GT3 ...

911rox

Strong results none the less... Porsche were over promising on the benefits PDK would have provided and obviously they have somewhat under-delivered in this particular test... I don't agree that tyres are a factor here, the factory has stated both are almost equal...

Nizer

Don't get the disappointment. Equivalent turbo's have always been faster that GT3. Can't beat the torque advantage. Most learn this PDQ at their first track day.

1/2-3/4 PDK car-length advantage per shift was always marketing hyberbole.

kosmo

cancel my order!

911rox

Exactly... Just talk... No action....

CaymanR-Racer

Turbos were faster than GT3s ??!! On a track... Normally not when driven to 10/10th ...

Especially in Hockenheim this wasnt the case so far...

997.2 GT3 = 1:10,4
997.2 Turbo S= 1:10,9

Both on MPSC+ tyres...

On the Nordschleife it was as follows:

997.2 GT3 = 7:40
Turbo S 997.2 = 7:44

also both on MPSC+
