Re: 2010 Nissan GT-R runs 7:27.5 at the Nurburgring.
Are these earth minutes they're using?
Dealer had a 911S with PDK at autocross yesterday. Said that when he went to Porsche they told him the PDK was good for a hard launch every 2.5k. And Nissan doesn't even cover it if you use it once?

Yeah, having a launch control that dumps the clutch as 4500rpm was very stupid.... no car manufacturer on earth would warranty a car if you dumped the clutch at those RPMs 30 times in a row (and I mean, back-to-back consecutive) .
The new launch control is easier on the tranny and doesn't void the warranty thankfully. I can't believe I am defending Nissan, but the warranty/clutch thing got blown way out of proportion.
Regarding the Nring times: Nissan is just trying to sell their SpecV & Nismo gear... I suppose their reasoning is, "look at how much faster we can go with just the SpecV WHEELS, so please buy them".
The wheels are $20k BTW.
Hell, the Nismo exhaust is $21k. Seriously. Twenty-one thousand dollars.
Ridiculous.

Mizuno: The SpecV is NOT the high-performance version of the GT-R
Speaking with Edmunds, Nissan engineer Kazutoshi Mizuno revealed that the SpecV is “not the high-performance version of the GT-R” and that another model is in the pipeline.
What Mizuno has in store is still anyone’s guess but one suggestion gaining credence is Nissan will build a road-going ‘homologated’ version of its FIA GT1 race car. The storied ‘LM’ badge (short for LeMans) is expected to be revived for the “high-performance” GT-R and output is rumored to be set as high as 592hp (442kW) and 506lb-ft (685Nm) of torque.
Expect production of the car to be extremely limited as pricing will probably be set higher than even the SpecV, which at $161,800 in Japan, is already double the price of the standard GT-R.
This isn’t the only new GT-R model rumored to be in development. Nissan is also expected to launch a ‘M-Spec’ model, a softer version of the car targeted at luxury buyers seeking a performance vehicle.[/QUOTE]
Re: 2010 Nissan GT-R runs 7:27.5 at the Nurburgring.
So if I get the sport chrono plus with pdk I could only use launch control once in every 2.5k miles? Otherwise I'll brake the transmission?
Are these figures only valid for 911s or for the CS as well?
Sport Chrono and Chrono Plus
This optional package is a valuable addition for trackday use. Available in conjunction with the CDR-24 CD radio, it includes a swivel-mounted analog and digital timer unit which is centrally located on the dashboard. All functions are easily accessible via the control stalk for the on-board computer. Analog dials measure hours, minutes and seconds, while a separate digital field displays whole seconds, tenths and one hundredths of a second. A second digital display runs in parallel in the instrument cluster. Click this Link to visit the FAQ entry for Sport Chrono.

Actually I have that same question!!

I would bet that if you abuse the car, you will run into warranty issues when you break things. Just like a Nissan. Just like a Mercedes.
Porsche might be more flexible because they are collecting huge premiums up front and can afford to do so, but don't count on it.
How often do people think it is OK to rev to 4500 rpm, dump the clutch, and pound through the gears to redline in a manual tranny?
I suspect that even without using the launch control, a PDK car will outpace nearly all manual transmission drivers. All it takes is a less than perfect shift to fall behind.
ChrisN's GT-R was plenty quick without using launch control. Especially when all six gears were working.

So this basically means drag strips are a no-no with PDK?!

Note the nationality - therefore 2.5k = 2.5 kilometres = 1.5 miles.... That might change the previous conversation! Sorry about that!
Edit - if you have a manual car and you do a drop clutch launch too often, and the clutch goes (which would be the usual first thing, I would think) and you come into the dealer with even 10-20k miles, I find it hard to believe that Porsche would cover the cost of a new clutch and term it excessive wear. So, if you do the same with a PDK, and the computer is probably counting the number of times to boot, I wouldn't blame them for saying this is not normal wear and tear. That being said, I watch the dealer at the xcross on Sunday do 10-12 full launches - I don't think I'd want to buy a demo PDK car - everybody must be trying these type of launches! Compare that to how many drop clutch launches a manual tranny demo car gets....none?
That said, PDK is a wet clutch, supposedly, so it's hard to say how much more robust it is (I've burnt out the clutch plates on my motorcycles before - and they're wet clutch- albeit smaller)

Watching the dealer’s PDK demo car applying the launch control was interesting. I’m having trouble believing that repeated use of the LC will not somehow shorten the life of the transmission & clutches, time will tell.
On another note, the drivers time was a full 2 second better than any of his previous runs at our AX events, +1 for PDK.

Yea - aside from the quicker shift, it must help to not have to put any focus into getting your downshifts right. Reminds me of racing karts 20 years ago ( I was lighter then!) where steering, gas and brakes were the three items of concern. And I've never been a good heel-toer!

Where can we get the times for the auto-x?
It is quicker but I'll most likely stick with the manual trans, it is part of the fun and I'm old school.
Unfortunately the AX times are not posted; Bill McCay the AX director keeps the records for the season. Ask bill about getting a copy at the next event on May 24th.
Re: 2010 Nissan GT-R runs 7:27.5 at the Nurburgring.
More food for street racin, GT-R haters.
Nissan GT-R R35 Moded vs Porsche 911 (997) Turbo Switzer SPI 750
Regular start...
GT-R has HKS mid pipe + 5 Zigen Catless exhaust around 550-560 HP...
This GTR has Cobbs ECU + HKS mid pipes + 5 Zigen catless exhausts, has no cats at all....making around 550-560 HP...both runned from dead stop and that is why GTR was able to keep up 1st 3 gears ))) also it runned 10.97 in 1/4 that night !!!
Re: 2010 Nissan GT-R runs 7:27.5 at the Nurburgring.
Not as much an advantage as I thought for about 200hp more and probably weighing less. The GTR gets a good launch because of its AWD I suppose.... Sort of stupid to be street racing - did you see the speed that they went by that first vehicle?
