That would be fun. I love that track! Have fun!

That was indeed a terrible terrible tragedy.. Many of us have PTSD from that thread. May it rest in peace

^ LOL, to paraphrase Twain, rumors of it's death may be greatly exaggerated.

FWIW, when I drove it up to 5500 rpm, I found the torque to be adequate, no more, no less. Not exactly sporty, but I have no doubt that it's a different ball game from 5500 to 9000. Throttle response was good though, which is arguably just as important.

Also, the seat heating appears to have better response than the 911S, although that may have been due to the hole it burned in my wallet!

At the lowest level the seat heating is hot. I bet on the highest setting it would burn ones' ***.

Funny how perception is. When I got my 991S I soon sold my 07 turbo because I thought the 991 was more fun to drive.

The GMG dyno looks pretty flat across the entire power band with increasing torque up through 5,000 rpm. From 2,000 it's at 220 TQ up through 5,000 where it peaks to about 280 TQ. Looks like a pretty typical low number Mustang dyno with expected TQ and HP. And, it's not like there is big problems with any part of the band.

It's not like there is going to be any problem with torque for getting started and certainly no problem with acceleration at speed with the horsepower this car has. Who is seriously concerned about torque when the car can do sub 4 second launches?

According to Porsche's Specs, the Peak Torque of all 3 Engines (C2S, C2S w/Pwrkit, GT3) is the same at 325 Ft. Lbs but the gearing in the 2nd through 7th Gears of the GT3 is much lower than in the Carrera
(See Reidry Post on Pg. 1) therefore the Torque at the rear wheels through the gears (Higher Torque Multiplier) will be higher. Also, the higher GT3 Engine RPM makes it possible to carry that higher torque to a higher Engine speed to produce higher HP. The 325 Ft. Lbs Torque peak of the GT3 @ 6,250 (HP Peaks at 8,250 RPM) is higher than the C2S so at similar Engine speeds below 6,000 RPM the GT3 Torque will be slightly lower, but at similar Road Speeds, with the lower gears, will feel equal or greater. Displaying The Torque Envelope on the GT3's Panel Display illustrates how dramatically the GT3's Torque rises between 5K to 9K.

^^What FastLane said. With normally aspirated motors of similar design and compression, torque is very much proportional to displacement. So, all the 3.8L motors are going to have very similar torque. But the higher redline and the lower gearing made possible by that will give a thrust advantage to the GT3 at middle rpm's (and a big advantage at high rpm's, where HP dramatically diverges).

What Jimmy and Mooty said!!

You gotta drive these cars on the "pipe."

That's ole racer slang. On the pipe means ***** to the walls. Otherwise, just use the Camry as your daily driver if you are afraid of cops and old ladies.

The higher rev limit of the GT3 is the key point here. A regular 991S redlines at a lower rpm and has to shift to a higher gear well before the GT3 does. As soon as you upshift, you lose the torque multiplication of the lower gear, which means there is less torque driving the rear wheels in the higher gear. In other words, the GT3 can keep pulling hard for a while longer before it has to upshift and gains a significant advantage on the 991S by being able to do that.
