Just came across this YouTube showing the 991s doing 0-60 in 5.96 sec with 2 passengers.


I wonder if the 991s times could achieve 0-60 in 4.1sec with 2 people on board.

Unlike many other cars or turbos which are not greatly effected by the extra weight it seems that all the NA Porsches 0-60 is dramiltcallty effected with a passenger on board

 

More importantly, cars are slower at elevations of 1 mile above sea level.

 

I wonder what times you would see at sea level with a passenger on board. I know in my 997.2 4s you can feel the difference in acceleration from a full tank of petrol and 1/4 tank. And I'm 30 meters above sea level.

 

It goes without saying that power to weight ratio is one of the major factors affecting standing start acceleration. So obviously adding weight to ANY car (i.e. extra passengers) will make it slower in 0-60. It may appear to you that some cars are not affected, but it might be that they are more traction limited than power/weight limited, another important factor.
All of the current/latest Audi RS cars put down some spectacular 0-60 times that seem to defy physics, mostly because of their quattro AWD systems superior traction. Same reason Panamera Turbos and 911 Turbos do the same. All of these cars have big power but proper AWD really helps too.
All this said, 0-60 times are more for bragging rights than real world use. I can count on one hand how many times I've "launched" my car from a stop since I got it.

 

Don't forget that the manufacturer times are with the combination of options that add the least amount of weight. All the full leather, super power sport seats, etc. add weight too.

 

Weight, Heat, Atmospheric conditions, fuel, tire pressure, and most of all, the nut behind the wheel all come into play when chasing a number.

It's a canard to say that a F/I car has less problems with weight, as that is not the case.

As far as the Youtube video goes, it's ridiculous. You don't chase a number at high altitude in the heat with two junk-food commandos in the ****pit.

You can clearly see the car was running rich and bogged off the line during the launch.

Also be aware that "launch Control" doesn't always obtain better results than a skilled driver. Case in point: the fastest 0 to 60 time recorded to date was accomplished with a Manual Transmission: 2012 Porsche 911 Carrera S (Manual) 0-60 mph 3.7 Quarter Mile 12.1

Pretty amazing the 2013 911 PDK C4S 0-60: 3.5 Sec!

Yes, it is impressive. It just goes to show what these cars are capable of when driven correctly. The all-wheel drive is killer for traction, but with enough practice, similar results can be realized with the two-wheel drive model. Practice makes perfect.

Case in point: Our hero in the ZO6 community is a fellow called ranger. He subscribes to the theory that modifying the driver is more important than speed modifications.

He is seen here turning a 10.7 with a bone stock ZO6 on drag radials. The stock ZO6 normally runs high elevens. Ranger runs 11.02 on street tires.


Ranger has a web page that explains his years of research on launching and shifting techniques, which can be applied to all sport cars.

 

There's the key! You go for speed there. BTW is also seems the clutches are grabbing at less than 3500 like mine. It lugs down like my old 2009S.

Indeed. Road & Track took the 991C2S from 0-60 in 3.5 seconds as well and quarter mile in 11.8:

How do the 997 Turbo S and GT2 times compare? 0-60?

Re: launching daily. Why not?

 

It should be all in here... http://www.zeroto60times.com/Porsche...mph-Times.html

 

Well that link can't be right.

Because it lists:
2011 Porsche 911 Turbo S 0-60 mph 2.9 Quarter Mile 10.6
2011 Porsche 911 Turbo GT2 RS 0-60 mph 3.4 Quarter Mile 11.1

Perhaps the manufacturer should ask our internet friend, Ranger, how to launch a car.

Orrrrrrrrrr

AWD is superior on take off than a more powerful, lighter RWD car, in a straight line race.

 

Interwebz racing.....

 

Once the HP gets high enough, AWD is a decided advantage in putting down the power off the line. Look at the list of streetcars that go 0-60 in under 3 clicks: GTR, Turbo, Veyron, Aventador. All 4WD.
BUT, re GT2 vs Turbo S times, it wouldn't be fair to mention another major factor at work here -- PDK!
