Can anyone confirm if the 997 turbo lapped the Nordschleife in the high 7:40's? If so, street or competition tires?

Thanks

 

What do you mean by confirm?

I can confirm that Motortrend said they lapped Nordschleife in 7:40 with PASM off, Sport Chrono on on MPSCs. But then again, Nurburgring times are probably meaningless to amateur, semi-pro and even professional drivers.

 

Meaningless, maybe not, for some reason it's become the new gold standard.
BTW, Doug said your looked rockn' when he was up at Dallas. Any more pics bobby?

Okay...meaningless probably is a bit strong. How about "not as useful as fanboys and zealots think."

More pics by tommorow...I hope, thanks. I hear Doug loves his conversion!

 

I totally agree with you, I don't know how an 8 mile plus road course with dozens of variables has become the gold standard down to the tenth of a second but it has!
The green hell lives!

 

its a better standard than say, 0-60mph times IMO

and not to offend anybody on here, but if you enjoy canyon carving and / or track work more than straightline highway pulls, its at least as relevant as 1/4 mile ET's.

 

Hesperus hit the nail on the head. I think the 'Ring is extremely meaningful and the standard. If not what is? Yes, there are many variables/conditions to contend with. Porsches, especially turbos, are like decathletes, not single event specialists.

 

[playing Devil's advocate...] It's not meaningful for a GT car specially designed to carry German businessmen up and down Autobahns!! So I don't think track times are really relevant for the stock Turbo.

The stock Turbo can come out of the factory with front wheels set at only 0 degrees 25 minutes negative camber! No wonder it understeers like crazy when trying to go around corners!!

Compare that to a stock GT2 which comes from the factory with a whole degree more negative front camber (and that's a road setting not track) and you start to see why the NBR times are so different!

You can't get more neg front camber on a Turbo without lowering it - something the stock (bottom of the range) Bilstein's fitted can't do. Cars like the Nissan GT-R have Bilstein Damptronics (top of the range) fitted which can change ride height and thus be set up for track cambers.

 

stock GTRs have adjustable ride height?

 

I have read GT-R's and Aston Martin DBS both use Bilstein Damptronics - which do have ride height adjustability.

 

It is my understanding the shock is adjustable but not the ride height as with the afterket coil over damptronics for the TT.

 

I don't see how this is helpful...at least with trap times, 0-100, 0-200, 0-300kph, 60-130mph pulls, the variables are more limited and multiple cars can be tested at once or at least during the same day. Nring times are subject to every variable of all other tests, in addition to traffic, and timing specifications or lack there of (GPS data.)

Are we going to buy the ACR Viper because it lapped 4 seconds faster than the ZR1?

Are we going to claim the GT-R 7:29 is acurate because there is a youtube video recording the event? Or are we going to proclaim that it is fraudulent because there is no GPS data?

Are we going to claim that Horst von Saurma is a better driver than Chris Harris because he can push the Z06 around the track faster?

In my eyes, nring times are nothing but propoganda. The best that you can do is say that one vehicle has a ring time in the same reference range as another...but splitting hairs on a 12+ mile course doesn't seem to support any arguments.

 

+1...I believe gm is correct.

The R35's stock suspension, Nismo variant, and V Spec suspension are on Bilstein non height adjustable coilovers...GT-R standard and Nismo have electronically controlled dampers...

 

Hmmm, interesting, then they don't use the top of the range Bilstein Damptronic's that I have on my Turbo - the B16 kit.

I'd still be very curious to know what the max camber settings are for the GT-R and how they compare with the Turbo.

 

I see both sides to the Ring as a performance standard. One it's the best all around test of a sports car, with tight turns , elevations and high speed straights over a grueling 8 mile course. On the other hand bickering over a few tenths of a second while trying to draw meaningful conclusions is almost useless. Maybe the best thing to do with data is look at the general times as a benchmark, for example a sub 8 minute time is excellent.
