In case you missed it. Best times as set by Walter Rohrl and reported in Automobile, 07/09: GT3(08)-7:45. GT3('10)-7:40. 911 Turbo-7:50. '09 Carrera S-7:56. '09 Carrera- 8:05. 911 GT2-7:32. Transmissions unspecified.

 

A 33 second spread between the GT2 and the base Carrera over the 12.9 mile 'Ring works out to 2.56 seconds per mile. This illustrates how competently Porsche builds their models from top to bottom, and the relatively large cost of incremental gains in performance.

I'd still love to have a GT3, Turbo, or GT2 if I could afford one

 

6 secs btwn TT and 09 CarreraS! Can't blame the driver

 

Did it say what kind of tires?

 

Nah. Not much info. You might assume w Rohrl driving these were production cars w stock tires. The Carrera S had a "sport suspension". The real ques to me is whether or not any pdk was in there. With all the flap on whether TT is faster than GT3 this post has been very quiet. Hmmm....

 

Another website reported that a 997.2s with PDK, sports suspension and sports tires did it in 7:50.

http://www.edmunds.com/insideline/do...ticleId=127326

 

Would have expected a larger difference, but the best times I've seen are 7:59 for the pre-facelift 997 S and 7:50 for the 997.2 S with PDK.

 

Remember I believe he also did a 7:59 in a 997.1 S..

Dave

 

Dave, I believe that a .1 with some mild intake @ exhaust mods will run w a manual .2 enginewise. The PDK is a new dimension but it does not make me want one. Have we learned nothing from "transformers"?

 

The 7:59 for the 997.1 was not with PSC's from what I believe.

Dave

 

I wouldn't no what to do with my left foot.

 

Where did you find all this info?

 

Here's a pretty good list...note it has the 997.1 S manual within .1 sec of a manual 997.2 S
