Is a 997s faster than a 997?
Car & Driver's Road Test Digest April 2006 lists the 2005 C2 & 2006 C2S at 0-60 in 4.3 and 1/4 mile in 12.8. I know Porsche lists the "S" .2 sec quicker. The C2 also stopped 1 foot shorter than the S. Any ideas as to why the numbers are the same?

Interesting, but I guess that the 200cc and 30hp won't be just there for nothing? 
What about passing speed? Anyone knows any test data between the two models in different passing speeds?
With best regards,

Test conditions make a huge difference. Air temperature, humidity, track temperature, track surface, tire conditions, different or same driver, etc. You would be far better off accepting Porsche's own data than anyone else's for these reasons. Most magazines are not that strict about testing and certainly fall well short of manufacturers' procedures.
The S is without any doubt significantly faster than the base model where it counts: in gear speed increments like 30 - 50 in 3rd, 50 - 70 in 4th, 70 - 90 in 5th etc. which is what you need when overtaking on the road.

There is always a significant amount of variation between testers, test conditions, testing equipment etc etc. For example, the 2S 0-60 mph times range from 3.9-4.6 secs (that's a huge percentage difference, but it is to be expected when car X is being tested in England at 55F zero sea level and car Y is being tested in AZ at 90F on a concrete runway....I'm just making this up of course, but you get the point!).
That being said, the difference in acceleration times between a 325hp and a 355hp Carrera is NOT going to be Earth-shattering. Does an S out accelerate a non-S, and does an S have a higher top speed than a non-S? Of course. Same gears with greater hp/weight ratio for the S.

Great numbers Karl...
After looking at all the numbers it seems clear the the 3.8L S is faster, but not by much. 1/4 mile average for 996 3.4L 13.3, 997 3.6L 12.9, 997 3.8L 12.7.
997's are about 300lbs heavier than a 996. It seems to me that if Porsche continues to increase the weight of the cars on every new model it becomes harder to significantly increase performance given the minimal HP increases they tipically give them.
