My Cargraphic powerkit conversion
Thought I'd put all these posts together...
Had the CG Kit2 fitted a week or so ago now.
RS-Tuning Powerkit 2
400KW / 544PS / 6200 1/min
798Nm / 3770 1/min
= BMC air-filter + 200 cell exhaust (medium loudness) + ECU
SportsAuto performance results
Cargraphic 997 Turbo RSC 3.6
544 PS at 6,200 rpm
798 Nm at 3,770 rpm
151.1 PS/litre
1550 kg
357 bhp/ton
MSRP: 176,757 EUR (with options as tested)
0-100 km/h: 3.3 secs.
0-160 km/h: 6.8 secs.
0-200 km/h: 10.4 secs.
Vmax: 316 km/h
Hockenheim short track: 1:10.3
Comparison with Ruf 550 kit
Plotted out the engine dyno comparison of the Ruf 550 (10650 EUR) vs the CG 544 (8495 EUR) kits:
If you add up all the PS and Nm across the whole RPM range you get:
So I guess the CG kit would be faster.
First Impressions
I also got a revised Parr geometry setup which I think makes the steering feel more precise and responsive and certainly handles the power a lot better. So big thumbs up there.
Further impressions
I had a weekend away last weekend, 300 miles round-trip. I still just can't get over how smooth the Turbos and acceleration are now!!
There is also hardly any lag - other than when cruising in 6th at 2000 rpm and you then floor the throttle. Then there is still a few seconds wait. Other than that much more like a normally aspirated engine. Great when accelerating gently through a corner. No more turbo on/off switch.
The car just feels 'tuned'. Not like it's had all that power forced upon it, it just feels more free!!
The exhaust sound is great too. Not brilliant 2500-3000rpm on the motorway as there is a bit of a drone. Nothing too intrusive, but if you hit 3000 and onwards you just get cruising silence. Sure, if you want to hear the good noises then they are readily available with some right foot action!
Fuel economy is about the same - I averaged 27mpg averaging 60mph on my 300 mile round trip.
So overall I LOVE the powerkit. Frankly I think the engine is healthier now than it was before so I am definitely less stressed about the warranty issue. Plus RS-Tuning (via Cargraphic) is probably THE best tuner for Porsches along with Ruf (although Ruf doesn't actually race Porsches) so they really know what they are doing. Also the ECU is tuned for the exhaust + filter combination, so I know I have a tried and tested formula. Yes, certainly worth the extra money compared to the other packages out there (albeit a bad Euro exchange rate right now pushing up the price).
As for the Parr 'fast-road' geometry alignment; definitely sharper more responsive steering. Definitely more stability and grip putting down all that power. The car somehow feels lighter!
I am desperate to get myself a 'Performance Box' and do some videos and sound-bites. What with snow forecast for this weekend, it may be a little while though.

If you add up all the PS and Nm across the whole RPM range you get:
- Ruf 550: 4200 PS and 7270 Nm
- CG 544: 4291 PS and 7370 Nm
So I guess the CG kit would be faster.
First Impressions
- Exhaust sound is great!! (not PSE hacked-open on a Carrera great, but still a vast improvement) Wouldn't want it any louder (I got the middle loudness version) and to me at least it sounds a lot like the Tubi from in the cockpit.
- Turbo lag is almost gone; the car now feels like it has a NA engine given how responsive it is
- Turbo kicks in a lot smoother as a result of the kit - you are soon doing frightening speeds in the blink of an eye. It even sounds smoother. When I put my foot down at low revs in the original car you would have a pause then it would feel like the engine was balling up all the power to then unleash. Now when I hit the throttle you just get an instant smooth surge of power. I much prefer this.
- I have only pushed my right foot to the floor 3 times thus far and only very briefly - and the results are startling! The upper revs of the gears just sounds SO 'angry' and it accelerates like the cars life depends on getting away. It honestly feels like I now have unlimited power at my disposal. The concept of needing sport mode with over-boost is now frankly ridiculous.
I also got a revised Parr geometry setup which I think makes the steering feel more precise and responsive and certainly handles the power a lot better. So big thumbs up there.

I'm looking forward to reading your reports as the weeks go by
