I (failed to) race today against a 911 Turbo (997).
A new 997 generation Turbo got behind me in the metro area of the city and was following behind me for several miles on the highway out of the city on my way home from work, when I got off the highway at my exit he followed me off. I then made my last turn onto a two lane road towards my hometown, he turns too and I see him swing out in the other lane suddenly moving up fast. So I floored it too, at which point the trans failed to find any of its four gears and just clunked around until I let off. Not that I expected anything less than to be dusted anyways.
The car was impressive though to say the least. I knew it was a 911 but didn't realize it was a turbo until it went flying by and I saw the badge on the back. He just kept on the thing too. He was doing at least 100 mph for the next mile or so, although I'd guess he was actually going even faster than 100. He was a spec when I saw him get back on the highway. It was impressive to say the least. Makes me want to just once be able to drive a Ferrari or Turbo or Z06/ZR1 or something.
