    Cargraphic powerkit

    Hi guys,

    I know a few of you have installed the Cargraphic/RS-Tuning exhaust system on your 997 Turbos, but I was wondering if anyone had gone further and added a powerkit with it?

    Powerkit 1 looks pretty good to me:

    http://www.cargraphic.com/index.php?/s,6,7,18,2987,2988,3103/



    Nice jump in torque!



    I am making some enquiries to the UK importer (Parr) as this is a route I may take next year if Porsche hasn't brought out its own Powerkit by then.

    The jump in torque is nice and predictable but the jump in HP is kind of mediocre (+62hp) after all 3 components upgrades.
    I have the loud CG exhaust and recently added the sport filter above (BMC). My ecu was tuned more aggressively here in the US and my total cost was a lot less than 8000 euros including 2 of the 3 components.
    I am very happy with the exhaust and the filter in combination with my tune, the car runs like a champ.

    Re: Cargraphic powerkit

    The hp curve is rather flat between 5000/min and 7000/min

    This should result in quite attractive acceleration times...

    BTW: The hp/torque chart describes the engine/exhaust kit and not just the exhaust kit

    Just got this email back from Parr:

    Quote:

    As it would happen we have just completed a 997 Turbo this morning, please find attached pics. The car was fitted with the power kit 1, Racing Headers and progressive rate lowering springs. I can say hand on heart that the transformation is eye opening and makes the car so much more involving. I drove the car before and after and while the car in standard trim is effortlessly rapid the upgrades just make the car so much more responsive with phenomenal torque/power increases and good exhaust/Turbocharger/Induction noise. We fitted the TETR silencer on this particular Turbo, which is the middle option of 3 sound levels and provides a sporty exhaust note while not suffering from resonance at cruising engine speeds. It's a very impressive upgrade as the performance figures indicate and I can assure you it will not disappoint.



    Hmmm, tempting...

    What is the price of the ECU mod? I already have the exhaust.

    The +62hp may not look much but it is RS Tuning engine dyno power. It is the maximum Porsche type hp which the VVTs can produce when fully hot/loaded.

    OK, I'm interested! Group buy anyone? I'd be interested to see how they compare to my current shortlist - Ray West and DMS.

    Only thing that worries me slightly (apart from the warranty issue!) is their website is claiming a whole series of conversions, culminating in a 687bhp version! Isn't it early days to have done that sort of tried and tested development?

    More news most welcome! On the Audi forum I use, a gang is collecting a list to go to DMS for their RS4s. They seem to get nothing but praise, although quite a bit more dough. Think it's 5k for the 997tt, not sure what the exaust system is.

    Don't be condescending. It is the maximum that the engine will put out reliably under every type of load. That means Autobahn driving, something which you don't have in the land of 55 mph speed limits .

    The 687 bhp version is basically the Alzen race car engine with SECAM intercoolers and all the works. The finest you can buy for the car, but no VTGs. The 618 bhp version on the other hand uses VTGs.

    DMS buys in"maps" from the grey market and more recently has taken to tweaking them via a chassis dyno. This is not the same as the race proven stuff which RS develop and Cargraphic market.
    The 687hp "kit" can be done on the 996tt and 997tt and is a fully reworked tt engine -to the tune of 110K Euros

    Basically, the equivalent to Ruf's Rt12 engine...

    P.S.: Are you aware of the warranty conditions available for this 687hp car?

    1.) Not responsible for injury or death in an explosion.
    2.) Not responsible for injury or death by fire.
    3.) Not responsible for rear of the car melting from all the heat.
    4.) Not responsible for any engine damage, which occurs while vehicle is moving.

    Is this it?

    But seriously, what are the conditions?

    Re: Cargraphic powerkit

    Standard RS Tuning warranty is:
    No guarantee for racing, For road use 6 months guarantee with a maximum of 10000km.....
    So pretty useless compared to a Ruf warranty....
    I am biased but would say that this is not an "equivalent" of the RT12 engine.
    An RS Tuning 569hp/770NM 996 turbo weighing 1600kg was timed 100-300kph at 20.9s. and 219mph
    The 650hp/870NM 1500kg RT12 which was tested at Nardo did the same sprint in 21.9s

    The 687hp RS engine has the Secan intercoolers(which is exclusive RS technolgy AFAIK) in addition to all the "special" parts which RS develop during their race program through affiliations with KKK race and the like -it will be scary fast but at a scary price and you won't get looked after for more than 6 months

    What about the "lesser" packages then? 598 or 618 bhp with VTGs. What are the prices and warranty?

    The Rt12 with a max-speed of 330kph (shorter gearing) does 0-300 in about 23s. Would you expect the 687hp version of RS to be quicker? If so, by how much? And... why?

    Personally, I would not expect any quality differences between RS and Ruf. Thus, why should the cars perform differently with simlar hp output?

    Re: Cargraphic powerkit

    Well the 569 RS car was as quick as the RT12 in the sprint between 100 to 300kph (despite being heavier) so one could assume that the RS 687 engine with another 100hp would be even quicker -my guess would be 100-300kph in ~16.5s for a ~1600kg tt.

    Ruf makes great "complete" road cars, RS makes the worlds best Porsche race engines. You don't see many "Powered by Ruf" stickers on race Porsches do you ?

    The problem with this logic could be: who knows whether the "569" RS car really had 569hp? It is quite easy to tweak the turbo engines and have more than 569hp...

    BTW: <20s 0-300 for a 690hp Porsche? Remember the Veyron does 0-300 in about 18s - with 1001hp...

    The 598 kit is listed by CG at 17K Euro
    My guess would be same warranty 6month/10k max !
    If you were to ask RS about the (how do I put it politely) "Limited" warranty you would be told of the hundreds of engines they have running for many thousands km with no issues - this is true and they have this as a reputation. Try booking your car in with them and prepare for a wait....
    The key to long life on these engines is in heat management which at over the 500hp level becomes critical with oval bores and melted heads a "knock" away -All RS engines are mapped in the same way as the race engines they do.

    This is where I would have to disagree - easy to tweak for a chassis dyno reading, hard to make the power hang around during a 300kph run.....What is interesting with the 569hp 996tt is its 0-200 was about 12s so not particularly fast (heavy car) but it made the time up between 200-300kph (bad tuning heat soak territory)
    You could be right about my estimate 0-300, possibly closer to 20-22s ? A lot depends on weight/gearing/aero

    12s for 0-200? Do you know which gearing they used for the test car? 569hp and a max-speed of just 310kph or so could help explain the 100-300 figure you mentioned above...

    It achieved 350kph - I've no idea on the gearing but presume 350kph suggests at least a longer 6th ?
    I know FlatSix mag also tested this car and got a 7.9s 100-200kph time which validates the 0-200kph in ~12s

    Well the SportAuto test on the GT2 with the 542 package was also pretty fast, 100-300kph 24.8s and 200-300kph in 17.8s with a top speed 330kph.......
    RS did not give me these numbers, they were from a test done by Hans-Jurgen Tucherer

    Re: Cargraphic powerkit

    Torque is the crucial element regarding transmission and powertrain - as good as it looks I wouldn't opt for too much torque if you want an reliable and daily useable car.
    Apart from that the dyno graph seems to be tweaked, that is definately not the original readout since torque and hp graphs don't correspond perfectly.

    Just my very personal two cents.

    12s for 0-200? Do you know which gearing they used for the test car? 569hp and a max-speed of just 310kph or so could help explain the 100-300 figure you mentioned above...


    It achieved 350kph - I've no idea on the gearing but presume 350kph suggests at least a longer 6th ?
    I know FlatSix mag also tested this car and got a 7.9s 100-200kph time which validates the 0-200kph in ~12s



    Why was RC's car so much slower then (with just 20hp less)? Honestly, these numbers of RS cannot be achieved by a 569hp car

    Another hint: sportauto once tested a RS GT2 (!) version with 540hp or so. The car did 0-300 in ca. 30s with less weight an RWD...

    There we are... The shorter gearing (you mention a max speed of 330kph) reduces 0-300 by about 2s, RWD vs. AWD reduces 0-300 by another 2s (both numbers based on Ruf information).

    Thus, a TT with the sportauto engine but AWD and a max speed of 350kph would do 0-300 in well above 30s, maybe 33s or so.

    This confirms my point: the numbers they told you must be wrong. Probably invented by RS' markeing department

    Re: Cargraphic powerkit

    It is certainly difficult to accurately determine this stuff - as I said, the aero/weight/gearing can completely skew things.
    How much power do you think the tt in the graph below has, it is running 2WD at 1470kg with 993GT2 bodywork sans rear bi plane.....
    In case you can't make it out 100-250kph in 12.44s.
    For reference the RT12 did it in 12s dead running weight unknown....
