I agree with the comments that there may not be much different power curves between the gts and S cars.

I feel the power difference is there at the low end. Minimal but there. However the sound is something completely different and that can't be replicated in an S model.

Yes. They are all fine for sure.

Imagine yourself from a moving position and one car is standing still while the other one has a 15 hp engine. 15 hp is incredibly much better than 0.


Does anybody have the specific torque curves for the GTS and the 997.2? Don't think I've seen them.

Archimedes

I'm guessing you weren't a math major. There is a big difference between comparing 15 and 0 HP, and 340 and 325hp... 15hp on 325hp isn't even noticeable; plus the GTS is 55lbs heavier. There is a 2.5% difference in HP/LB in these cars, which is immaterial.

Go look up the quarter mile times of both cars at the various magazines. They're near identical, varying form 12.6-12.8 seconds at 108-113mph, each car higher at some and lower at others.

Both cars with PSE should sound identical provided you are not talking about the new 911s coming out with turbos. The GTS and S have the same engine, you can get the S with the power kit which now it is identicle to the GTS so not sure here the sound is different..

Examining the torque curve between both cars, it's clear the 'S' has a little more low end torque and the GTS has more high end power.

Goto 7:13 and check the acceleration difference between the 385hp GT4 & the 430hp GTS.

Apart from the initial launch with traction advantage goes to the rear engine GTS, there is nothing between them.

Archimedes

The GTS is also 200lbs heavier.

Mass is irrelevant at those speeds. It's aeorodynamics that's in play. The more power the better a car can rip through air. The 911 has a drag (as in air resistance) problem when compared to the GT4.

I just test drove a manual GTS and can say for sure the sounds are actually different. I have a T4S with PSE. the gts sounds meaner - more raw. Not sure if I prefer it over the 4S with PSE how ever which has a more base laden note.

I understand the logic in your thought process, but my GTS sounds better than the 991S with PSE . That was the way with my 997 GTS also. It definitely sounded better than my 997S I had with PSE.

stratocaster69

Is it more throaty sounding or more of a higher rev sounding note? Thanks

Archimedes

Nonsense. That's a drag race. Weight is absolutely relevant to the comparison. Aerodynamics doesn't matter much until the cars are up to speed, but power to weight ratio certainly matters in how fast each car gets to that speed.

And you're wrong on your second point as well, as the 911 actually has a better drag coefficient than the GT4 (.30 vs. .32).

The other thing that people need to factor in is that, while Porsche only claims 385 BHP for the GT4, initial dyno runs indicate it actually makes just over 400HP at the crank, dead on the C2S. So the idea that it's detuned from the motor in the 991S is more marketing/product line differentiation than reality.
