C&D did state that the way they launched it was a redline clutch slip and did not recommend it. I honestly don't doubt their time. The weight of the car and the stock dyno numbers I've seen all add up to a possible 13.5 run fairly easily. With AWD, that sounds like a mid-high 4 second 0-60, especially with the 5 speed.
There's also a video on YouTube of professional drivers testing the 08 vs the 09 WRX, and the 08 got 14.3, where the 09 got 13.3. Here's the link:

Regardless, it doesn't matter. :P My butt dyno says this thing is as fast or faster than my friend's 07 STI. lol
