Lol. You are so stupid. First of all, a Turbo S can do 9.6 with Pzeros. I don't care about your Dunlop maxx what ever. Motortrend have shown Pzeros are actually more consistently fast off the line than trofeo Rs.
And secondly that everyone knows when Porsche says a car can do 0-200 in 10.9, the car CAN do it, and even faster. The car doesn't "start with 10.9 and end up 9.9" with a rocket booster in the back. The car will probably do low 10.2 to begin with. Porsche give realistic performance figures that in ideal circumstances, can be bettered. /facepalm A less powerful, heavier, less grippy GT3 can do 10.9, a more powerful, wider track lighter GT3 RS will better that.
Just cuz an engine has max power at say 605hp, doesn't mean it always has 605hp. Most of the time it has between 400-600. A Porsche TS has a very flat power curve and from 5k revs to redline, it maintains at least 90% power the whole time, averaging about 95% power when accelearting. So climbing through the gears, the Speciale avgs 500-520hp only, while the TS actually avgs about 550hp.
A Porsche TS does NOT have more power than a speciale. It keeps up because 1) it's AWD, 2) at lower speeds up to 100mph, power isn't as big a factor, 3) at higher speeds, the Porsche is much more aerodynamic.
Ferrari lose in those drag races because a lack of torque. But in turn it is quicker in trickier conditions compared to mclaren.
