No I think they're taking a page from the 997 book and using dummy exhaust tips - you know, in keeping with the Porsche tradition of form over function...

Can any of these 991 Powerkit mods be made on a 2005 C2S?

DrJay

no. The 2005 C2S and the new 991 have completely different engines. I think there was a power kit for 2005 cars, or perhaps other sources for mods, but not the 991 power kit.

Has anybody seen curves of torque and power delivery on power kit engine? I have power kit 991 on order to be delivered in September (still waiting for the final confirmation but Porsche told my dealer that it is fine to add this option now). It would be nice to know more about what it does to engine apart from adding 30hp. Thanks.

Yes, it was floating around on the internet a few weeks ago, just after the club cab release. I can't find it any more despite Google's best attempts.
To my way of thinking it was pretty shocking - hope it was a fake. It had absolutely no change to power and torque all the way up to 6000 RPM or so - only after that did power rise (but not torque) relative to the standard engine where power drops slightly. 30HP increase relative to the standard was shown at 7800 RPM.
If this is true, the kit is pretty worthless.

Actually power kit is almost useless even if there is a bit more torque in a mid range. I don't think it makes any change to the real world speed of the car (what is 0.1 in 0-62 sprint? it is almost inperceptible). But 911 is in the end of the day is not the most sensible car anyway. Its main purpose is to make you feel good. And power kit, I guess, has to be judged in the same way. If +30hp make you happier (works for me) than it is worth having one.

That is a good summation of the mind set one should have when buying a Porsche. It applies double to any options added to a car.

Rainier_991

Yes, I suppose that sums it up pretty well.

I think you'll be surprised by the difference in feel. The 381hp in my '06 X51 is definitely perceptible over the 355hp in the "regular" 997 of that era.

Rainier_991

The powerkit for the previous models gave much more difference over all of the rev band. It was worth while.
It looks like the power of the standard engine has now improved to such a degree that the power kit does not make much of a difference anymore.

The 0.1 second faster sprint time quoted has nothing to do with the extra power. It is due to your wallet being much lighter...

One thing I've learned about P over the yrs. Even though everything seems really expensive, to a large degree you get what you pay for. I don't think that Porsche would offer a kit like this, calling it a performance upgrade, and have the difference not be significant. I'm looking forward to seeing the tests of this car.

I can imagine that if my last minute addition to specification comes through, I will be one of the first owners (late August delivery) of power kit 991 in the UK. I will tell you what I think and how much difference there is (hope I will manage to arrange back to back test drive). It should help people who want to order/not to order power kit on rational grounds.

As for me I have some healthy irony towards this power kit with "exclusive" badges and silly price so I don't expect much. But if it makes significant upgrade to driving experience I will be happy and a dash surprised.

Roman Dudinov

That's a good one.

wonder why Porsche hasn't released power and torque comparisons with Powerkit and standard?

Looks like I was wrong. $17800 as now shown on the Porsche website. It's basically $13000 for 30hp and some fancy engine trim once you subtract the included PSE and sports chrono. If you can wait, it likely will be standard on the gts model whenever that arrives at a better value.
