I was surfing around and noticed this thread. Is it correct that the GT3, up to 6000 rpm, has less torque than the 991 Carrera S (with or without the Powerkit option) ? If true, does the gearing of the GT3 make up for this at lower rpm? For those that have driven both, does the GT3 feel weaker than the 991s up to 6000 rpm? Thx

I have yet to take delivery of my 991 GT3 and I have not had the opportunity to drive one. On the next page of the thread you linked I gave the following response....

Here's a comparison at 3500 rpm where I could get a good measurement on the graphs, 991S X51 making 380 Nm, GT3 making 330 Nm. Pretty close to the widest separation in the torque curves. Torque to the ground is higher in the GT3 across 2nd through 7th gear.

991S X51
Final Drive 3.44_____x_________wheel torque
1_________3.91____13.45_____5111
2_________2.29____7.877_____2993
3_________1.65____5.676_____2156
4_________1.30____4.472_____1699
5_________1.08____3.715_____1411
6_________0.88____3.027_____1150
7_________0.62____2.132_____810

991 GT3
Final Drive 3.97_____x__________wheel torque
1_________3.75____14.887_____4912
2_________2.38____9.4486_____3118

7_________0.84____3.3348_____1100

Torque at the ground in 1st easily overwhelms the tires in either case.

No, it doesn't feel weaker. It also doesn't feel decidedly different until about 6k RPM. From that point forward, very different.

Really? I couldn't disagree more. The 991s loaner I had must have been a dog. No comparison in throttle response and acceleration. Not even close.

Hoopumpers

Ok, I give up. I hereby rescind any and all comments which could be perceived as remotely negative towards the 991 GT3. All heresy

I pray the RS becomes a possession, so I may be welcomed back into the family.

All I did was disagree. I drove the 991S daily for 2600 miles, then immediately picked up the GT3. The difference on the throttle was night and day. You are not unwelcome for a differing opinion. My apologies if my comment came off harsh.

LAGinz

Didn't Porsche do some type of software update along with the new engines that was supposed to have some effect on lower end response? Can't recall exactly what it was though.

doubleurx...you did nothing wrong, I think everyone is on edge because of the "road test drive" thread?

I agree with doubleurx.

You can not look at torque and make direct comparisons. It is a whole different package and that what baffles one when you understand it

There are plenty of sport cars with more torque(on paper) that do not even feel as fast and powerful.

Figure this- I think my 997.2 Turbo had in excess of 450 for torque(I have to look it up) and this car is faster and feels equal to more powerful. - whole different experience

There was some speculative chatter about that on the various forums, but I don't think there was any actual evidence of an upgrade. Admittedly, it was 4 months between driving the car with the old and new engines, but I couldn't tell the difference.

JUST STEP ON IT,
do not drop below 7000, we will not b having this conversation
I never felt sny gt3 lacking in tq. u guy are lugging the motor
stay bn 6-9000 rpm

ipse dixit

That was my experience, during my limited test drive of a GT3.

Initially, I just chalked it up to being "polite" during the test drive, but then did a bit of research and confirmed what my butt dyno told me.

^ mooty is right. This car is made to be driven high in the rpm range. It is not for every one.

This car reminds me of the days in the mid-80s when I used to race dirt bikes Yamaha YZ ext). We all use to love to hit the 'power band' in the gears. When you hit 6000 rpm this engine shoots you like a "power band". I do not know how else to describe it but may be the above works.

Can't remember who posted a similar comment recently (would like to give credit) but it's so funny that different people can observe the same phenomenon and reach completely opposite conclusions. Gotta love it....

FWIW, the GT3 feels much more responsive than my 997.2 S (I know, not a 991) and in general I agree with mooty; keep the revs up and you won't have any issues with a motor that feels weak....

Anyone bringing a GT3 to Thunderhill this weekend? I'll have my 991S. We can figure it out :-)
