Note, I said 991 RS, not standard GT3.

Cut-off is always at least as high as tach's redline. So, probably cut-off between 9k and 9k2

Pretty ignorant statement unless you have 4 brake pedals and 5 legs to master them all.

I'm afraid ideas like "beat" (and all lap times) will become meaningless with this next generation of stability electronics and PDK. It won't be enough in club competition to just have points adjustment for PDK, it will have to be a whole separate class with its own times.

I expect 0-60 acceleration will be shockingly quick with launch control, especially if the up-shifts are allowing some torque multiplication).

Porsche will no doubt keep this GT3 respectfully "below" the RS 4.0 in its times but that will be a contrived pecking order.

Is the GT3 still at 3.8? Presumably the 991 RS will be at 4.0 (or larger?) Here's praying for dramatic improvements to feel and feedback.
I think the GT3 has to be 3.8 if the Carrera S already is, regardless of whether it's truly a new engine (with higher specific output).

I think he's saying that you don't need PTV if you can trail brake. Not sure how that relates to how many legs you have.

I honestly don't see the benefit of it either unless you have AWD.

I guess suspension tuning is antiquated now as well.

It means you can now trail brake like a retard and not have to worry about rotation or being smooth on and off throttle since the retard sensors will fix it for you and keep the car from over rotating. Probably will also make the car feel like it understeers even more, mean while it eats up your brake pads and rotors.

His point was that to be as effective as PTV you would need to control breaking force on each wheel independently, for which you would need 5 legs. There should be no doubt that PTV done right should be faster than any human can be, simply because humans just do not have controls for doing what PTV does. I do not know how I feel about PTV on track yet though - hope it's not removing control from the driver.

Um, but I'm pretty sure PTV only does the rear wheels and not the front. PASM does the braking on the front wheels. The brake on the inside rear wheel to help rotate the car. Pretty much it's just an electronic LSD.

So I would only need 1 extra foot then?

PTV is bad news for rear rotors and brake pads. Just ask my buddy whose rear ceramic rotors are worn down to the indicators after ony a few track days.

Boy am I glad I really love my 6GT3 I could never master all these new acronyms PSM, PASM, TC, PTV, PDK, PMS etc. I have a hard enough time just driving and remembering how push 3 pedals.

Maybe the new GT3 will also get track specific PPD (Porsche Piloted Driving)???

You are right. I was just interpreting what the other poster meant.

Actually, if you think about it, PTV can be manually replicated with two feet (assuming RWD) - right foot applying throttle and left foot applying brakes to the inside wheel. No need for brakes on the outside wheel - you can just give less throttle.

Which prompts a thought - when I left-foot brake (started learning this year), I overlap brakes and throttle a little bit on turn entry. I can see how PTV could mess it up. Hope it does not.

According to reports that comes at the cost of increasing rear pad temps and wear as a trade off for the increased performance it generates, which depending on upbringing is either wonderful or immoral.
