I was yesterday at the track with a friend and his 997s chrono. We have similar driving level. I made 1mn58s with my plain Turbo ( the best time of this track day ) he made 2mn0s with his car. We put slicks in his car and a "pro" ( the European Truck Champion of this year) drove the 997 chrono: he made.....1mn47s. Very, Very close ( in this track) to the GT3 times..... It made me think a lot.....

 

Oh, I forgot... There was a Ferrari Maranello that made 2mn.05 s...... ( Big smile...)

 

The 997S is a nice and fast car indeed. The 996TT just feels much faster during hard accelerations though.

 

You should have put the "Pro" in your tt and he would have beat the 997 time for sure.

 

You have to realize that the 997 w/chrono is Porsche's *best* N/A 911 - their latest technology, the most power, and the best handling. A stock Turbo is not Porsche's *best* Turbo...the best would be an X50 Turbo with X73. So at a minimum, a Turbo with X73 should be the platform to compare the 997S chrono against - and my bet goes on the X73 Turbo being significantly faster. Porsche made the Turbo in stock form too "GT". It's too soft in the handling department. Porsche *should* have made the X73 option standard...it's a huge difference.

 

The best would be to compare N/A with N/A and Turbo with Turbo.
The X73 Turbo will be significantly faster than the 997S indeed.
