Has porsche ever supercharged anything? We know they do turbos well. I kinda would rather have batteries than a supercharger. But thats just me.

Seems like everyone hates superchargers, is there anything actually objectively wrong with the technology or do they just get a bad rap because they’ve traditionally been put on not the best cars?

Parasitic power loss. Heat soak. And yes, it evokes images of joe sixpack with his Camaro with fuzzy dice hanging from the rearview mirror.

I’m no engineer but those sound like problems associated with slapping superchargers on as an afterthought and not building it that way from the ground up ...hmm I guess that does negate my idea of putting it on the 3.0L though so touché.

If I recall correctly even the mighty C7 Z06 had overheat problems...

I suspect the tweaks to the engine will be very simple e.g. variable turbine geometry - simple and very effective, uprated acctuators - again simple and effective. Both of which will enhance spool and waste gate activity.
The equivalent of the current S turbos moved to the new base, the current GTS turbos moved to the new S and the 992 GTS to receive new turbos.
More suspension tweaks, again largely tuning for improved weight distribution rather than significant changes.
8 speed PDK with 3, 4, and 5 slightly shorter.
350mm rotors at rear please and 380 at front please (in S and GTS) -
An extra degree added to RAS please
EPAS - tuning, more weight and slightly faster rack
Weight - needs a lot of work - getting far too heavy

Isn’t the 991.1 the only generation that’s been lighter than it’s predecessor? My understanding is that’s due to increased use of aluminum, so I would expect the next 911 to get lighter than it’s predecessor to be the first one that uses a lot of carbon, and that will probably be well down the road.

Track Day
Really liking everything I am seeing with the 992. Hoping to pick one up as my first jump down the 911 rabbit hole - my Macan GTS lease is up March 19 so hopefully good timing.
For you long time 911 owners, what roughly is the price increase from generation to generation? Did the 991 get much more expensive than the 997.2?

It's going to be the same engine. Porsche is not going to design and build a new Turbo engine for only 2 (maybe 3 years). The Base/S/GTS are going to get it. It will be tuned with about 20 more HP. I don't care about the dash at all. It needs to work ergonomically which I am certain it will. I care about how it drives which will be fantastic.
I don't see 8 months as realistic either. Here is what we know from the rumors:
http://www.automobilemag.com/news/porsches-reinvention/
When do these new 911s arrive? Here’s what we know:
• October 2018: Carrera 2S and Carrera 4S coupés revealed, with first customer deliveries February 2019.

• October 2018: Carrera 2S and Carrera 4S coupés revealed, with first customer deliveries February 2019.
Carrera: 385bhp - 332lbft
Carrera S: 434bhp - 384lbft
Carrera GTS: 464bhp - 406lbft
Engines start getting built Q4 2018 as you can see on the slide. LHD customer deliveries will start in Europe in early late Jan/Feb 2019. RHD cars will follow.
You can find this information on the slide attached (bottom cells). This was leaked market data and has been available 6 months. All the recent announcements have been correct to this slide so I believe it is indeed 100% correct.
Note the only car that sees increased torque is Carrera S. Those more cycnical would say Porsche are simply stating what they are already delivering with the power levels in all three models! Non the less these are simply ECU tweaks.
The 992 engine and drive-train I believe will be identical to 991.2. In the later generation 992 we will see hybrid and 8 speed PDK.
The biggest changes to the 992 are cosmetic. Rear valence (2017 Panamera style) and interior family update (2017 Panamera style). The coverage area of the new automated rear wing is also 20% larger than the prior vehicle adding more rear down-force at speed. the front of the vehicle is very similar to 991.2 other than alteration of front hood shut lines and minor styling tweaks. Naturally we will see new wheel and tyre options.I believe brakes are staying the same.
These changes are sure to divide similar to the 996 launch in 1997. Fundamentally this is not revolution but rather evolution with the biggest changes still being the 991.2 move to 3.0T power-plant across the range. Each to their won with the aesthetics (I prefer the more traditional 991 shape rear and 911 style cockpit with analogue dials and push buttons). As always the performance and handling will be improved over the outgoing model, along with the features and functions...

Yes. That is very interesting indeed. Those engines have not made it to production yet and appear to be beyond the Q1 2019 scope of the document.
Not all engine on that sheet will necessarily make production.
Of course one could also theorize that these are the new 718 Spyder and GT4 engines!
