Official 991 POWER UPGRADE KIT
 
Hi Guys,

my dealer told me today, that there will be very soon, a Tequipment upgrade. It will be called "Carrera S Power Kit", and it will give at least +30 Hp (Like the Club Edition). I don't know the price yet, but i'll keep u informed.

Enjoy. :D

tromero 06-04-2012 10:07 AM

I wonder if they will make something for the 3.4 as well

Elias74 06-04-2012 10:35 AM

Really don't know, but i think no...

DaveKrek 06-04-2012 11:13 AM

More or less than $17K ???

Personally the 991S has all the power I need, but I'll still be curious if the kit is a bolt-on or requires engine modifications. Does anyone know in the 997, if adding the X51 meant swapping out or modding the engine?

It's also interesting in light of the cover story in Excellence this month, which described how TechArt decided to focus on exterior mods for the 991S since the OEM performance was already so efficient that to squeeze any performance gains out of it would be prohibitively expensive.

Someone with more technical expertise can help here but a true X51 997S involved a lot more than the headers, PSE and intake. The throttle body was completely different as were the heads, wiring, software, etc.

@ Tromero - powerkits were not offered on the standard Carrera with the 997 series car and I doubt they'll be offered on the 991 as the likely price increase is pretty close to the increase from non-S to S.

Rainier 06-04-2012 01:36 PM

Lifted from Google's search result for the just released 991 upgrade:

"The Carrera S Powerkit contains modified cylinder heads and camshafts, a newly developed variable resonance-type intake system with switchable flaps, center radiator, a sports exhaust system with two dual tailpipes in a unique design with a concise sound, the Sport Chrono Package with dynamic engine mounts, an optimized engine management plus a new engine bay styling with a
titanium-colored cover and inserts in carbon fiber."

Cost should be around $17000, its about 14000 UKP.

So, let's see - 30 HP extra, but only at the very top end of the rev band. Really the very top where angles dare not go. No change anywhere else.
No increase in torque anywhere.

Well, I'm no racing driver. My wife calls me a slow driver. I don't quite get this one - what is the point ?

There you go: you can now build your very own a 991 Club Coupe: minus the specific Brewster Green exterior paint and painted wheels, "911 Club Coupe" decals on the doors and Club Coupe laser engraving in the trim strip.

Or another way of looking at it: X51 for the 991. Factory warranted power package. It might be expensive, but for those that want that extra power (and track from time to time), it probably makes a lot of sense.

jordanpryce 06-04-2012 05:53 PM

I'll just wait for the GTS and get all that power at 1/2 the price. ;)

You are so right. Earth to Porsche - low end torque please. This beast has plenty of HP. I am not saying everything over 130 mph is a waste, but what I need all day, every day, is more pop between 0 and 80 mph - you know, speeds you can actually do!

Elias74 06-05-2012 12:29 AM

Well, Torque will be welcome.

I'll give You more info as soon as i get some.

Rainier 06-05-2012 12:57 AM

The powerkit is available on the Australian builder application.

I found a nice power/torque comparison graph yesterday comparing the standard with the X51 kit for the 991.
I can't find it anymore, should have made a note of the link - but Google found it so I'll try again.
The ONLY difference is power right at the very top. Absolutely no difference anywhere else.
Porsche claims 4.0 secs to 100 with PDK and sport+. That is a 0.1 second improvement. That is practically nothing, certainly not worth the money.
No I am not saying that this is not of ANY value - I'm not qualified to make that call - but I would like to pose the question to those that do take these things on the track - it this of any use ?

Interesting thread.
It would be worth comparing this to the previous generations power kit and hearing the observations from those owners.

Well, looks like the previous X51 provided a bit of an improvement, but looking at historical power kits the improvement is getting less with every iteration. This gives validity to the statement posted earlier that the stock engines are now pretty close to peak and any improvment is not likely to count for much.

Judging by some of the test reports for fairly recent iterations floating around on the net the consensus is pretty much to leave this box unticked when specifying a build. Utterly pointless for road use (even if the devil is in you) and marginal at best on the track.

I'll will definitely not be selecting this on my build which should be close to closing now anyway. If I could get another 50Nm of torque at 3000, it would be worthwhile and noticable. Don't care about the power - it's torque that makes a sports car. Low down torque please.

What's the bet we're going to see two electric wheel motors in the front in the not too distant future ? Instant, linear additional torque (for a limited time) and makes traditional 4 wheel drive history. Now that's a hybrid that makes sense to me.

Rainier 06-06-2012 09:20 AM

Yes, but that is just an impractical development step on the way.
The crux is the energy storage. The motors are fine right now.
The development is focusing on two things: Firstly, the conversion of wheel energy into electrically stored energy. The amount of energy to be strored in a short time (during breaking) is huge - too much to handle practically just yet - but it is going to happen.
Secondly the storage itself. Let's call it a battery for arguments sake. We need a solid state replacement for the flywheel. At least 95% efficiency to avoid too much heat during the conversion process.
A super battery, almost like a giant, oversized capacitor would be.
It's not here yet - but it will be. Couple of years ? We'll see.
There is lots of space in the 991 in the front. Who knows - perhaps the X52 power kit will be more of an option. Trouble is, I'll be really old by then.
Thanks for the link. I was only aware of the 918 development. It is obvious this is getting closer... :eek:

On another note - I would imagine the forums will go up in flames if this comes out considering how much chatter the harmless electric steering caused... hilarious

got X51 in my club coupe, had 997C2S before it.

30hp is not noticable with street driving. On the track long straight, X51 will pull slightly away from non-X51 from 50 to 100mph. Probably one car length ahead at 130mph.

Definitely not worth $17K. I will pay up to $5000 for it due to sport exhaust and carbon fiber airbox (not sure if available in 991).

Rainier 06-07-2012 02:30 AM

BTW, there are some interesting similarities between what you see in my avatar and the 991 I am patiently waiting for:

1) They are both white (just kidding).
2) They both have a boxer engine. 4 cylinders in the Sling, 6 in the 991.
3) They both have dry sump lubrication (external oil tank in the Sling).
4) The Sling does 0-60mph in roughly 4-5 seconds, similar to the 991.
5) The Sling has 100hp, the 991 has 400hp but power to weight is nearly identical.
6) Both can give you an immense thrill and kill you one second later - but both make you feel "alive".
7) Both have two seats.
8) Neither comes with a spare tire.

Some differences too:
1) The 991 is faster: Top speed ~310km/h, the aircraft tops out at ~230km/h straight and level.
2) The pilot does not worry about speed cops, the driver does...
3) The aircraft needs a runway at the destination, the car goes anywhere where there are roads...

So next time you get into your 911, do some pre-flight checks and report to the tower, "ready for takeoff".

Fwiw: The Powerkit for 997.1 was some 12k$. Reviewers stated it offered a smidgen more top end noticeable in upper gears. The main selling point was the exclusivity and the pretty carbon fiber airbox (big bucks). Given the lack of access to the 991 motor how they will match this remains to be seen. Carbon fiber engine shroud perhaps? Keep in mind it is an option which will have little residual value at resale time but may make it an easier sale. Or not. More top end is a joke here in my opinion. The torque of those rumored electric motors will make the kit moot. Have fun guys :)

Yes and No. a 991S with the Powerkit is still a fast 2WD car with a NA engine, which is totally different from a turbo. your reasoning is right for people who are just interested in more hp and more hp/$.
I personally love the NA engine and will work on it to squeeze out a bit more power in the future, but at this point, no interest in a 991TT. Maybe a 991 GT3...

Agreed. Completely.
Even better - this obsoletes traditional 4 wheel drive.
It's very interesting from a technical point of view and by being able to apply as much (or as little) torque on either wheel as needed in an instant regardless of RPM - it may just open up a leap in performance. Since it's still got a real engine in the back - it's still a real car with real car noises.

I'm going to be happy with my 400hp. More than I can handle or need anyway. Perhaps one day I can revisit this...

amg offers a performance package that includes engine, brakes, limited slip, and some interior bits for under $10000. porsche is a little out of control with this one. maybe they just like to make the gt3 seem like a great deal

I'm not super familiar with Techart or the other German Tuners but Techart has definitely done performance kits in the past (e.g., 997.1 Turbo: sport air filter, new manifolds, Techart Turbo chargers, high performance intercoolers ECU upgrade etc.). I think there's a major market demand for tuners adding bolt-on 20-40 hp to 911's (or at least pretending to). Hence the huge performance mods market on the 997. So, I think it is meaningful that Techart didn't even give it a shot with the 991... at least yet.

Excellence -- I've seen them give both positive and negative reviews to tuners (such as RUF) and overall I find it to be a pretty objective magazine. Big fans for sure, but able to criticize Porsche or the aftermarket when they feel appropriate.

I read about this on another website and wasn't that thrilled. Very little real world power increase. 30hp seems substantial but if I remember correctly the 0-60 time increase was only minimal.
That won't stop guys from buying it though. Many guys never grow out of bragging about catching the biggest fish or having the more powerful car.
I don't know why Porsche is taking so long to put out the turbo anyway.

RoninW 06-29-2012 08:10 AM

what they need to do is offer a reflash that is reasonably priced.

If it's anything like the 997 x51 kit $17k for 30hp is just insane, and that doesnt include the sport exhaust that you "must have" to install the x51. Heads (no cams), engine harness, carbon airbox cover, intake manifold, reflash, and some other misc items...cool if $$ is not an option but 30hp can be achieved much easier and cheaper.

It seems the amount of X51 kits left on the shelf gave birth to the 997 GTS model and i'm sure this will the case with the 991
