992 5.6 to 5.8 100kph to 200kph is fast stock.

991.2 with Cobb is 5.1 to 5.4

991.2 stock is around 6.5

M8 100-200kph looks like 6.69 to 6.86 seconds. Also very fast for a stock car !

Wow that 992 moves! Over a second faster than the M8C in 100-200 mph is something else. Realistically. The M8C is just slightly behind the 991.2 which is quite an old car at this point.

Even when they took off the M8C jumped and the 911 pulled by it like it was nothing.

Looks like the 911 turbo is still the best daily driveable supercar with hyper car performance.

Take out the stupid scores, looks like an easily clean sweep on performance, handling, and braking for the 911.

I was amazed by the 992 Turbo S 5.6s 100-200, that means it is quicker/as quick as a 488 GTB. That is just mindfuckingly fast

The question is, how does it manage do that with more weight and less advertised power than the 488?

Has to be area under the curve advantage with 30 lb feet more tq and peak hp over a wider rpm range , then gearing , drivetrain loss come in as well . Finally , Ferrari advertises a BS dry weight for every car so actual weights are much heavier.

Spot on, the tq and hp curves have to be sweeter in the usable rpm ranges vs peak rpms. Im not sure about the tq splits and AWD parasitic loss as the 488 is RWD but Ill bet the P car just is more efficient in the driveable ranges than the 488. Im not remotely saying the 488 is slouch but just making assumptions in regards to this unique comparison.

This might be meaningful:

Turbo S 590 lb/ft of tq at 2400 rpm and 640 hp at at 6750 rpm
488 560 lb/ft of tq at 3000 rpm and 660 hp at 8000 rpm

Ive never seen dynos of either car but....

Awd Drivetrain loss is a disadvantage to the 911 so....

Don’t forget that the Ferrari motor is bigger at 3.9 and running 20-22psi(pista) vs 3.8L and 17.5psi on the 911.

Did porsche lower the compression from 9.8 to 8.7 on the new turbo(still a 3.8L), thats even less power at the same boost!

I know the answer to this mystery, lets see if you guys can figure it out. Vic has the right idea....

Car and driver quotes 17.5 in 1 article and 22.5 in the other lol:

22.5psi -> https://www.caranddriver.com/reviews...turbo-s-drive/

17.5psi -> https://www.caranddriver.com/news/a2...rbo-s-details/

What most people don’t know is that the standard 488 rarely hits 15psi of boost, far from the advertised 20+psi

992 does have larger displacement. 3800 CC vs 3745 CC. Small but being precise here. They did lower compression, but did add bigger turbos (GT2 RS side I recall), and boost went from 18.1 to 22.5. There is also some additional torque multiplication going on with the hearing in the 992 as well.

Also Ferrari quotes dry weight so they are significantly heavier in the real world than they lead you to believe. Also not surprised they would be hitting different boost than claimed.

It's 22.5 , journalists are getting awfully sloppy now. They elected to go to a higher boost lower compression set up with bigger turbines which allows much higher top end power while keeping charge temps and cylinder temps down at the expense of some lag .

The 992 will be a special ride. Especially with the better AWD vs the 991.2
The 992 turbo manifold design is a casting based on the 991.2 GT2RS.
991.2 TTS has a billet compressor wheel that is pretty trick for its size. 58 mm at the base and 62mm at the wheel tips The 992 has a 60 mm at the base. Probably 64 at the tips. Not monumental, but a nice upgrade.

Biggest upgrade is the 992 turbine is 4mm larger. Plus they went to an internal gate for quicker cat light off. The IG will not add flow but the larger wheel does.

The 991.2 GT2RS has even larger turbos. Around 70mm base compressor.

But there is the digital gage vs analog and the nubbin issue. Plus 86lbs more weight.

Overall it will be better but “different “.

With lower compression, less displacement, more weight, and larger turbos one would assume it to be less responsive. Maybe the extra gear/shift speed from the pdk will make up for it lol....

Not bad at all at 10.4 at 137mph. With a better hook should be a 10.2 ride.

6.76 60mph to 130mph is nice too. My 2019TTS stock was a 7.4 Tuned its quicker than the 6.76 But a 6.76 stock is a killer improvement.
