    Re: OFFICIAL: 911 GT2 RS (2017)

    Can anyone confirm or debunk the rumor that the factory will shut down in August and September of this year?

    Yes, there is something slightly mesmeric about intercoolers. My favourite view is from the 288GTO

    If true, why is the factory giving build dates for US cars in September? If Porsche knows it’s going to shut down in September it could easily just scheduled US cars for October. yes

    Excited to see how the GT2RS's water sprayed 700PS fares against the 720S;s 720PS in a 0-300kph power/traction play Smiley

    0-300kph in 19.4s

    Also interested in what the car actually weighs in its presumably Weissach road trim, I am expecting 1475kg but  Smiley

     

    Here we go, 720s about 3,5 sek faster to 300kmh and track time on normal sport tyres simular to the street tyres time of the 720s 1:29,4

    They're probably very close on a track if you give them the same tires. Cup2 have typically been more aggressive than Corsas.

    1.28,56 on Cup2 N2 vs 1:29,4 Corsa

    very well said...

    and looking into braking date, the 720s is as well a head, 100-0, 200-0 and 300-0 as well despit the magic tyre R of the Gt2RS

    All great cars with great times though with varying target markets/uses. However, once thing is abundantly clear - the 720S is a phenomenal all round package which is currently unmatched by anyone. I did a long motorway run with plenty of traffic the other day which ended mercifully with some clear twisties - could have been driving two different cars its that good at both purposes.

    Many thanks Mcracing1 for the data Smiley

    The GT2RS does what Porsche said it will do it is only Mclaren moving the game on which undermines the GT2RS's excellent numbers. the 250 to 300kph acceleration does indicate that the 700PS is reaching the limits of this set up, probably the VTGs with their inherent hot running nature and the 1.5bar boost they have to run at.

    The 1501kg is quite disappointing when the 997GT2RS could be easily specced near 1400kg but I guess there's not a lot they can do with the 991 platform it has become quite lardy Smiley

    Agreed, I am sure it is. However, the astonishing thing is that the 720S would not be far behind on the track and recall still with wonderful hydraulic steering.

    So formula shows that the following amount of extra power is absorbed by the 991s CdA versus the 997s CdA

    255kph +11hp

    275kph +14hp

    285kph +16hp

    300kph +19hp

    In other terms at 300kph the 991 needs 357hp to maintain that speed whereas the 997 needs 338hp so theoretically the 991 has 700-357 = 343hp accelerating it versus the 997 620-338= 282hp available for acceleration.

    Obviously it works a bit differently to this as the acceleration is following the torque curve as it rises with the revs but since both cars have similarly shaped curves it is quite valid.

    My conclusion, the 991 VTGs are struggling at high loads due to temps even with the bigger exhaust turbines..... in my Mezger tuning journey the biggest VTGs they could make (with small 997Gt2 turbines/housings) maxed out at about 740PS, bolting on similar sized compressor side on a K24 platform gave another 100hp without other modifications all down to the limitations of the VTGs. Note of course the 720S seems to be able to make strong high end power using conventional turbos enhanced with twin scroll and full electronic wastegating.

    Re: OFFICIAL: 911 GT2 RS (2017)

    It is pretty clear that for the road with occasional track visit the 720S is the car to have. It also looks and better and more importantly YOU CAN ACTUALLY BUY ONE if you want. If I cared for these kind of cars, I would totally get the 720S and forget the rest (Porsche, Ferrari which you cannot buy either, Lambo...). It was also mentioned that the 720S was tuned to be more fun on the street with smaller tires. Kudos to McLaren. It even looks way better than the GT3 cars with the wings... Can;t wait to see a 720S Roadster or what a 720LT could do on the track.

    The low depreciation is only as side effect of the fact that YOU CANNOT BUY ONE. And the day you will be able to buy one easily, the deprecation will be the same as a normal car... Better yet, save lots of $$ and BUY one of these CHEAP used 720S that are so cheap and so plentiful...
