997.1's are slower in rolls but should get you off the line with a decent driver--- in 6 speed manual they are slower because driver error is involved with loss of boost at each shift. Those higher 11's times are coming from great drivers.
I had a 997.1TT and it was faster because it was a tip but it still wasnt close to my 997.2TT with PDK. The transmission makes a great difference in so many cars. I say this alot here- the DCT is so efficient it really allows car with more weight to cover the difference. Plus the F10 is much easier to drive than a 997TT stick.
I miss my 997.1- unique look
