Christian,
While I agree with you most of the time I have little bit different view on 991 GT3 Supertest results and comments from HvS. Even I exchanged few emails with my P source and told him that car did not reach Porsche claims in few areas(BTW, not only Porsche but, also claims from few well respected members of car press like Chris Harris or Steve Suttcliff)... Where you will ask?
-for the first time in recent Porsche history Turbo(S) is faster on the track then GT3. Personally, I do not have any problem with that. I would be pretty pissed if my 200K € car is slower on the track then similar shape 150K € model(no matter how sporty it is).
-second thing is pretty tricky one and has to do more with subjective "feeling" how sportscar should feel in its limit. SA clearly claim(and I do belive them!) that 991 GT3 is pretty tricky to drive on the limit. Remember what CH and SS claimed? That car is maybe even "tamed" in comparison to 997.2 GT3 models and that "everybody" car drive it fast. So, either SA stuff is wrong(and they are not) or CH and SS simply drove 991 GT3 way too slow and it did not show that tricky behaviour tendeny on its limit.
-real "feel"... It is most subjective thing in sportscar perception and Porsche has made an decision to give pretty different overall "feel" to 991 Turbo S and 991 GT3. What is right and what is wrong. Both, I guess but, people will here argue most.

Just look at the power and torque chart of the GT3 vs Turbo S. If I am correct, the latter makes at low to mid-range more than twice more torque than the GT3 and almost twice the HP!
Depending on the track, no wonder the GT3 stands no chance vs the Turbo S.
Another comparison I find interesting is the chart of the GT3 vs that of the Carrera S engine. Below about 5,500 RPM the GT3 pulls not more HP than the Carrera S engine and never more torque, regardless of engine speed.
