Official 991 POWER UPGRADE KIT
#16
Enjoy:
"With a stab of the throttle, the kinetic energy in the spinning flywheel is automatically exchanged for electricity – the charged ions power two strong electric motors on the front axle. Instantaneously bestowed with 200 torque-laden horsepower, the sticky Michelin slicks claw at the pavement with a vengeance. I clench the wheel as the carbon-fiber bodied race car lunges forward with more accelerative force than an F-16 fighter jet at takeoff power.

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...
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...

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).

I'm German (living in South Africa). I like Porsche. I want to believe this is not the case. I'm having a hard time though, I admit...

i like it too. and i love u guys.

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...

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
#27
I completly agree with You.

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.

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.
