Re: 991.2 GT3
- Press Release: 2017 Porsche 911 GT3 Cup -
New edition of the world’s best-selling racing car
New 911 GT3 Cup with ultra-modern drive
(29 September 2016)
Stuttgart. Boasting a completely redeveloped drive, the Porsche 911 GT3 Cup will take to the starting line on the world’s race tracks from 2017. The rear of the world’s most-produced GT racing car now houses a 4-litre, six-cylinder flat engine for even more drive. Thanks to thoroughbred motorsport technology, the compact engine with direct fuel injection delivers peak performance of 357 kW (485 hp).
A range of innovative details also improve efficiency in addition to engine performance, ensuring even better durability of the naturally aspirated engine in racing mode and reduced maintenance costs. A valve drive with rigidly mounted rocker arms and a central oil feed is being used for the very first time. What’s more, an integrated oil centrifuge is used to optimise oil defoaming in the engine. A crankshaft with significantly increased rigidity has also been installed.
A new front apron and a new rear end improve the downforce of the new 911 GT3 Cup and therefore enhance traction and performance. The prominent 184-centimetre wide rear wing has been retained from the predecessor model. The wheel dimensions are also unchanged: One-piece 18-inch racing rims with a central locking mechanism are used – with 270-millimetre Michelin racing slicks on the front axle, and a massive 310-millimetre tread on the rear axle. The intelligent aluminium-steel composite construction ensures maximum rigidity and a lightweight body. The new 911 GT3 Cup is ready to race weighing in at just 1200 kilograms.
The engineers have also once again focused specifically on driver safety during development. The driver is protected by a solid safety cage and an innovative, bucket-style racing seat that is moulded particularly heavily around the head and shoulder area. The enlarged rescue hatch in the roof, in line with the latest FIA standard, makes it easier to provide initial treatment and recovery following an accident.
Porsche manufactures the 911 GT3 Cup on the same production line as the 911 road car in its main plant in Stuttgart-Zuffenhausen. The basic race tuning is performed at the Weissach motorsport centre, where vehicles are also thoroughly tested by a professional race driver prior to delivery to the customer. Some 3031 units of the 911 GT3 Cup have been built in the 996, 997 and 991 model lines since 1998. This makes the brand cup racing car from Stuttgart the most-produced and most-sold GT racing car in the world.
The new 911 GT3 Cup will be used in the 2017 race season, initially exclusively in the Porsche Mobil 1 Supercup, which is held alongside the Formula 1 races, and in the Porsche Carrera Cup Deutschland, as well as in North America. As of 2018, the car will also be available for the other brand cups. In total, Porsche is organising 20 of these race series for customer teams around the world, with the 911 GT3 Cup being used exclusively.

Thanks - very helpful 
Re: 991.2 GT3
KresoF1:4.0l new DFI 485hp
It's interesting that peak hp comes at only 7,500 rpm (the 991.1 GT3 and RS peak at 8,250 rpm). Given that the GT4 motor has only 200cc less and makes peak power at 7,400 rpm, it's interesting to know that they get 100hp more here. I think it's because although the GT4 is rated to peak at 7,400 it really peaks below 7k on the dyno (must be intentionally reigned in). The GT3 will be on a steep power curve up to 7,500...

Re: 991.2 GT3
nberry:I guess there will not be a .2GT3RS next year.
Don't worry, Nick...Porsche will try to "milk" the 991 cow as much as possible before the next generation will be introduced on a completely new platform. So chances are pretty good you're going to get your RS.

Probably some sort of limited edition track focused model like Cup Edition or RS 4.2L, etc...

Re: 991.2 GT3
Whoopsy:The .2 Cup car engine is basically the same one from the GT3R, and not from the current GT3/GT3RS.
Correct me if I am in error, but from one of your earlier postings I gathered the new .2 GT3 engine will have engine technology from the .2 Cup and GT3R that address/solve the oiling issues with some/most .1 GT3 engines?

Yup, which is why I wrote 'not from the CURRENT GT3/GT3RS'.
The .2GT3's will be derived from the .2 GT3R/.2 GT3 Cup engine.
No reports of a GT3R race car blowing up their engine, so I am guess the new oiling system for the top end seems to be working.

That's good news. How many hours/races have those cars run on their original motor? I think it's interesting that Porsche is advertising that the new Cup motors can run double the hours as the previous Cup before requiring motor rebuilding.

That is interesting. Do you remember whether they also specify how many running hours that actually is?

Went from only 50 to 100 for the motor and doubled from 30 to 60 hours for gearbox (see page 8 below):

Thanks for that. That is quite a contribution to reducing the operating costs of a Cup car.
Would surely have made more sense though to raise the recommended between-overhaul life of the gearbox to 50h instead of 60h, just to align it with that of the engine? 
Maybe the engine guys and the gearbox guys aren't talking to each other.
