Wow.. when I started this thread I never thought it would lead to some much controversy. Maybe the boys in Stuttgart will read this thread and think twice about power levels and engines in the 911 in the future.

I have really enjoyed reading and respecting everyone's comments and opinions.

But to me it's clear. Porsche should have never put the 3.4 in a 911. PDK or manual, it just doesn't matter.

They will argue that they need to improve fuel economy etc. Honestly... how many of us really care about gas mileage in a 911. If you are worried about that maybe you purchased the wrong car.

Maybe I have purchased my last Porsche!

Anybody complaining about low-end torque bought the wrong car to begin with. The same discussion pops up once a week over at the M3 forums... both engines need to be revved hard. And both engines excel on the track where you wanna be in the high-rev band. This is where the 911 shines... base and 'S' version.

You can spend a lot less money and have a stop light racer that will kill any super car. Buy a C63 and put a blower on it, or save even more money and buy an EVO with an AMS package... you'll be eating 458's all day long.

The 911 has a different philosophy and needs to be driven accordingly. My 650 hp e92 M3 was a monster on the drag strip, it had so much power that traction was my biggest issue, wheel spin in all gears but 6th. My 991S won't push me into the seat, but the super linear power curve makes it so easy to control and regulate.

Also, I actually make a conscious effort not to drive fast around town, people already think we are ******-bags.

Completely agree, if you want a high torque at low RPM car, buy a C6 (or C7) Corvette; it's a lot less expensive.

Maybe a few mods like this will have the same effect on your 991.
This may make a big difference in your driving experience. That and a reFlash of the ECU, if your car doesn't have Sport Mode.

I currently have a 2009 C2 PDK. I test drove both 2013 C2S and C2.
My 2009 C2 did feel faster than the 2013 C2, it felt heavier for some reason.

The 2013 C2S is an amazing car and it put a big smile on my face after smashing the pedal to the floor. I will be upgrading to the C2S version in the near future.

This morning I decided to try something new and you are all correct. I manually shifted the base PDK, shifted at 3500 rpm and the car came alive. I put it in sport mode also.

Snappy acceleration crappy mileage. Then again I can always drive my prius if I want to sip gas.

Yup you are correct it's the PDK programming to save gas. Sport mode is a partial cure. Manual shifting is key.

Did you try the quick accel to make the RPMs jump to 3500 trick? If you do that, it seems to put itself in sport.

When the head of BMW M since the beginning found out EPA would force M cars to go turbocharged in favor of mpg's and torque efficiency he stepped down and retired. If exotics all had torquey, low revving, none responsive FI motors there really wouldn't be much to differentiate their engines characteristcs from a stock Dodge Neon SRT other than numbers.

I could've turbo'd my stock motor and made 200 more hp and 350 more ft/lb of torque than swapping in an E46 M3 motor for thousands less but I am track junkie who demands precision. Also I find cracking shifts at 8400rpm far more enjoyable than driving a torquey V8, even if I do have to rev it out more in a daily commute.

A base model 991 manual will run mid high 12s at 111 + mph. It also spins 7800rpm stock. That speed is 993 turbo territory without the drawbacks of a turbocharged motor. Porsche would loose a lot of customers to cheaper competitors if they made all their engines characteristics similar to what you get in turbo PT cruiser. Exotics and track special cars use high revving, race car like motors for a reason, their customers demand it...

You don't really need to put it down all the way, just quick. Unlike a normal take-off, the engine will rev up to 3500 and then up from there.
When I first tried it, I thought the tires were spinning, but there was no squeal. If you have PSE, I wouldn't turn it on with people around because it's bound to make some noise.

I do care about gas mileage. I pay between 9 and 10 dollars per gallon.
And no I did not purchase the wrong car. But it sure sound like YOU DID !

What makes you such an authority?
How many Porsche's have you owned?
What is your present car?
