You will see a C2S PDK keep up with a 500 hp Gallardo. Not bad for a car that is less 120 hp. I think that if this race was done from a stand still the PDK would have done even better!
I'm sorry, but I would not call that keeping up.
I typically do not like to compare cars that are modified, but if you could add power and improve driveability with such ease, while not having any downside, the Turbo (with an ECU flash) should be a simple choice.

What is the max boost EVOMS 700 kit achieves? Just curious.

Unfortunately until a 1/2 mile or mile track opens(wouldn't that be great) somewhere the 1/4 is all we can go by..legally. Also I thought the discussion was about stock cars.

Not to belittle your comments, but you may not have chosen the best video to use in your argument. That video shows a spanking...if you have to film the opponent's care through the side view mirror, game over. Look what happens when the same car goes against a 997TT:
http://www.youtube.com/watch?v=PHcYy2_peSo

And from a dig, the Carrera may have PDK, but the 997TT has AWD. A clutch slip from 2800 is more than enough to pull ahead.

Ignore the fact that the PDK Carrera left a little early in this video, but the PDK Carrera may be on par with the 996TT:

At the risk of sounding too defensive, I don't think it's a silly comment. I spent 1/2 my life in the cold and snow of the northeast. A decade in the difficult conditions of upstate NY. Many drivers of AWD cars would develop a false sense of confidence with their vehicles that is evidenced when they find themselves needing to stop the car at a rate that simply can't be fulfilled while FWD and RWD drivers would not be pushing it as hard. No issue about the starting/steering thing. But braking is a very important factor to be the weakest link.
In a very high powered sports car, it makes the car safely drive-able by a larger number of relatively average drivers and enables acceleration times that would otherwise be unachievable. A slight loss in steering feel is a very reasonable trade to harness and apply all that power.
Just my view.

Looks like the porsches dud very well versus the lambos and the 997 with pdk beat the stock 996 turbo. Am I wrong?

It is absurd to think that a 997.2 pdk can beat a 997.1 turbo or gallardo. My statement is that these new pdk cars can keep with the 997.1 turbos to a certain point from 0 mph. I was trying to figure out what that point is. Has anyone ever run the two stock cars side by side in a linear run? I have seen articles in which pdk cars have been able to post 0-60 runs in the high 3's and quarter mile times in the high 11's. Is this true? Has anyone in a stock C4S or C2S pdk car run these times? These are 997.1 turbo times. I know that after third gear the turbo will blow the doors off the C4S pdk car but up to that point I think it will be close.

No way it beats a 997 turbo. I think it would beat a stock 996 turbo

I didn't say that it can beat a turbo. It cannot beat a turbo. These new pdk cars can, however, keep up with a 997.1 turbo to a certain point from 0 mph.

Seems I am the only person who has some real world drag #'s with a new 997.2 PDK...my fastest 1320 is
a 12.21 @ 114.5....with a 1.91 60'....I am sure I can get in the 1.8's and close to 12 flat but need better conditions...JUST FOR A COMPARISON.. a Ferrari F430 at the same track ran 12.2 @ 120...
I WILL BE MORE THAN WILLING TO RUN A STOCK 996TT..JUST NAME THE TIME AND PLACE. Don't read anything into my thread..I always race purely for the fun and enjoyment of it!!

eathvy, the best #'s I have seen for a gallardo was a 12.4...seems they are handicapped off the line (this was not an LP560 or superleggera) believe they were 2005 and 2006 cars.

Yeah, okay, I 100% agree with that. All the drivers in SUVs who think their "AWD" makes it okay to speed in the rain/snow are very dangerous. I was confused because this thread is talking about how fast cars can go, and of course 4WD makes a car much faster in bad conditions.

Using this data:

PDK Carrera S
0-30 mph 1.5 seconds
0-60 mph 4.1 seconds

Turbo
0-30 mph 1.4 seconds
0-60 mph 3.5 seconds

After the first 1.5 seconds (30mph) the PDK Carrera S starts falling behind. In 3.5 seconds (60 mph), there is a 20-40 foot difference.

So, the PDK Carrera S "keeps up" for maybe 1.5 to 2 seconds.

Besides the first 0-30 if trhe Turbo driver can't engage the power assist clutch properly he'll get left standing on the line and have to make up the time lost. It's a tricky clutch so driver skill comes into play and with PDK it can factor out human error.

BUT -- even the worst skilled shifter will still beat the 997S and he'll pull him before second gear ends . In fact once he hits thrird .. he's gone and if he makes it to 4th .. out of sight.

And that's why the track versions of the 911 (GT2, GT3, GT3RS, Carrera GT) are all RWD, right?
