Tuned Gen 2 Turbo now on sale

[bobfair]

Speedart have launched a tuned Gen 2 Turbo with an extra 80 BHP and 120 NM of Torque driving through a PDK box

http://www.gtpurelyporsche.com/newsitem.asp?newsID=140

So is the DFI unit with a PDK box going to take all this power and torque. Over to you Alex!!

Crikey, they didn't waste any time! Alex's will still be faster..........[]

Interesting, let's take a look:

So 40hp more than mine, 10Nm less torque though. I would assume PDK box is right on the edge of torque limit with 790Nm.

3.2s to 60mph is what quite a few stock PDK 997.2 Turbo cars have achieved already. It's the manual figure that is the most telling, 3.5s to 60mph, mine is tested at 3.3s by SportAuto mag []

Nothing on 0-200 or to 300kph though, but with 580bhp I would expect good things! Also 10k euros compared to mine which was 6000 euros (which is already x3 what other tuners charge for StageII), so perhaps they have had to strengthen quite a few internal components which is why it costs so much. The big question is how drastically will it shorten the lifespan of the gearbox and the engine?!

So it doesn't sound like they have strengthened anything.

I wonder what affect the light weight bodykit has on the performance results though?!

guys
dont shoot me here, im a total porsche man, tuning , kits every thing but we just cant beat this gtr, we have got 1cc more, 15 bhp more at approx 6000rpm,46 lbs ft more torque thru a larger rpm band, 34 bhp per tonne more , 150 kg lighter and this thing still eats the pants of our gen 2 turbo. How do they do it are they telling porkie pies. We need answers.

Personally Hugh I couldn't really care less what the GTR can or cannot do! It could lap the ring in 6 mins but I still wouldn't want to look at it parked in my drive. [] I do think, from what I've read elsewhere, that there are a number of "hidden" running costs. You wouldn't want to pop the pedestrian protection system, for example!

When the GTR has been dynoed some owners are getting a genuine in situ figure of well north of 500bhp as well as significantly more torque. If you dynoed a 997 as its not on the he move and the airflow into he engine is restricted you'd expect it to be between 5 -15% less (assuming DIN correction which is conservative).

So basically the GTR has very similar Power to Weight ratio, then lots of trick electronics to make it faster round corners.

Autocar this week did a three way test GTR, R8 V10 and Gen 2 TT. V box acceleration figures gave the Gen 2 tt at 3.2s to 60mph, and 7.1s to 100mph. The GTR was 4.0s to 60mph and 9.0s to 100. So in a straight line its about 0.1s quicker than mine to 60 and to 100, so a Gen 1 tt is faster and the Gen 2 leaves it for dust. The GTR had the best track time by 0.3s over the TT. So that tells you everything.

I love fast Nissan's - I had two 200SX's over the years but they are not the same as the Porsche. The TT is a fast road car not a Fast track car. Also be wary of Ring times - Porsche set much tighter restrictions on the tyres, suspension components and set up that they use than other manufacturers ie Porsche's are much closer to a production cars (they are supposed to use tyres and a set up configuration that will be provided on some of their road cars).

One of the car Mags took a GTR and GT3 both in standard road trim and set up and gave them to a well know ring racer who went noticeably faster in the GT3. Nissan were none to happy and I believe got the lawyers out to ensure the magazine was careful what it then inferred about the cars relative performance.

The GTR is a great car however the rumour persists that a very large amount of money is lost on each car sold, as is often done for Halo models. Porsche require the combined GT/Turbo programmer to make money and be profitable so a different pricing model is used.

So the long and short of it is for most people - what do you prefer. The GTR is incredibly fast especially round corners with all its very clever electronics but it is play-station, you are removed by 1 degree from whats going on, the Porsche involves you more so might not be as quick.

You pays your money and takes your choice but personally I see the GTR s more a rival for the Audi RS4/6 type sports saloon and would happily have either on my drive for regular long commutes but give me the Porsche for that country road blast every time.

As I see from the "advert" above presumably not, as they are going to bring out a 650bhp version which, again presumably, will have more than 790 torques. Think I would let someone else experiment first though![]

Only if you are Stevie Wonder or wear (very) dark glasses when outside the car[]

Very interesting post from Toby over on the Rennlist board:

Latest from the engine dyno.......

Following on from Porsche engineers telling them "this engine is not for you" RS Tuning got a willing customer with a new DFi turbo.

The engine broke a conrod at the 550hp level, I don't know the protocol for the engine dyno testing but it is quite rigorous with 3 days testing....

So the weak points are the conrods, pistons and head gasket.

RS is re-engineering this dead engine for the customer who has a nice shiny new 997tt.2 sitting high with no motor

They are making it 4 litre, special boring process, having different head gaskets made and Carrillo rods - They are not over cofident that the re-engineered lump will last very long..... It seems the new engine will need quite a lot of development to become reliable when tuned..

So anyone thinking of remapping their Gen2 Turbo should perhaps think again.

 

[okellyt]

Interesting post Alex, so should a Turbo S buyer be worried......?

As with any new engine it'll take a couple of years to identify and iron out any foibles, then a bit more time for the tuners to work out what they need to do to tune the engine reliably.

If I was buying a Gen 2 TT or TTS now, I defiantly wouldn't tune one. And I probably wouldn't buy one until they have been in production for over a year at least.

You stand your ground Tom!!
It's quick enough for this mere mortal as it stands and I'll have two years to try and break it so not worried (yet!)...........[]

 

[okellyt]

It took a pointless poster to spot the deliberate mistake........

it would take me a year or two to learn how to drive a TT or TTS well enough to appreciate the power it currently has. Mind you there is no such thing as too much torque.............
