Now we are talking...what about differences between 997,1 tip and manual?

 

PDK , launch control. extra Hp -- all make a huge difference but I also think the Dfi engine ability doesn't get as much journalistic attention and it's ferocious.

One of the first things i noticed in the normally aspirated car was how immediate the response is. This video at about 10 seconds shows that a car with less Hp than a competing 996tt (stock) can get such a jump that it took a long time to catch up.
It's one more advantage the 997.2tt has .

Agreed. PDK is the way to go with performance advantage.
It's shift ability is astounding and mated with the Turbo that amounts to boost retention into each shift. That's huge!!!

 

There are very few test of the tiptronic car for some reason. I for one would like to see a comparison of tiptronic vs pdk...

 

That TT started in the wrong gear. That was aweful. Listen to how long it takes to hear the revs climb. Of course the shifts in a Tip are going to be slow, plus it loses hp to a manual, not to mention a pdk so it's going to get whooped. But that was pathetic. He started at the bottom of third (second?). Must have been using the manual buttons on the wheel too because I would expect the Tip to automatically downshift in that situation.

 

Not to mention we're talking about a difference in HP of ~35 on a Tiptronic. This is a example of a turbo's boost threshold and lag, not the superiority of PDK.

 

I expected somone to point to a driver flaw in the race with the 996tt and perhaps it exaggerates the point but that same 997.2 NA car is in other races with other cars too .
It beat the M3 wheras the 997.1 did not . One may point to driver flaw in each race or notice that the combination of PDK and DFI not only picks the right gear (over tiptronic, Dct, and many manual inexperienced drivers ) but also leaps the car forward as soon as one touches the pedal.

 

Automobil mag in Sweden just tested the new PDK 997TT, in 2006 they also tested the tiptronic

2006 Tiptronic/ 2010 PDK w/LC
0-100km/h 3.6 3.6
0-160 8.0 7.5
0-200 12.0 11.4
their test track 53.3s 53.2s

I would say the tiptronic performed well on the same track!

 

That's probably the slowest time I've ever seen anyone launch the the 2010 PDK in Launch Control mode!

Mine on pump gas with me at the wheel did 3.44 seconds 0-100 and 7.38 to 160 with the engine still not fully broken in and in very very high ambient temperatures.

Other magazines have achieved 3.1 seconds 0-100.

Strange results!

 

And the fact it hits 60mph in 3rd gear. Probably the most aggressively geared performance car on the road.

 

Having put a few hundred miles on the 997.2TT the car feels significantly faster than the old one, even after mods (headers, cats, exhaust and tune).

The car just feels ready to go all the time. Lag is gone. The gearbox is so good that you can see why in a race it would be nearly impossible to do better in a manual. The old tip car could be faster in a drag race if you could launch it right but that was hit or mis, at least for me. On the old car if you were at a stop light and without trying to break torque the car you just mash the gas nothing significant happened until you got rolling and the revs came up.. The new car jumps off the line. They really have done a great job with the new transmission and engine combination.

As to the car just being faster due to the PDK well I doubt it. My butt dyno tells me the engine is stronger down low... I suspect that the larger displacement and higher compression ratio gives it a stronger feel and a better torque curve. The peek power numbers may be similar but the car feels like it pulls harder down low.

I also noticed that the sport button seems to make the exhaust louder, independent of RPM or gear. Almost like there is a baffle in the exhaust that opens up.

 

man, after reading this thread. I feel that I better get good at driving stick. I am glad I bought tt stick since the tt PDK cost double and most important I cannot afford. I guess I didn't made the wrong decision. I dislike the tiptronic very much so. I guess I better learn to drive better and keep in the boost!! haha oh well. I just dun wanna get smoke by tip tts.

 

The 997.2 is faster then 997.1 even without the need of the PDK
The 3.8litre with direct injection gives plenty of torque low down
The engine and the car is also slightly lighter
Evo mag tested the Turbo S recently. the midrange of that car is ludicrous!

Why some car mags got better figures for the Gen 1 turbo
Many factors
1. Atmospheric temp---make a huge difference in turbo engine
2. Differences in optional equipment--a fully loaded car weigh more than a car with no option
3. Driver----bodyweight or any passenger on board Some 6 foot plus German test driver weigh more than 100kg (I am only 68kg)
4. Road surface

Talking about PDK vs manual -If you look at Porsche own figures the PDK C2S is quicker to 100mph from standstll but it is slower 50-75mph in 5th. They didn't bother to list the later for turbo models!

 

3.8lt engine is DFI while 3,6 mezger engine is not...DFI by definition allows for much more CR before detonation or preignition occurs...By having a look at CR of 3,6 and 3,8 engines we see that one is 9 while the other is 9,8 (if i recall correct...)This is the main reason for the new engine to have less lag and better throttle response in low RPM...compression ratio...

 

+1. I also believe that there are so many 'good' things about the .2 cars - that are visibile, or manageable by the driver - that the DFI upgrade doesn't get much attention. But it is logically a huge jump in capabilities. The accuracy of the fuel management, the response to throttle input and the ability to program the fuel dispersion pattern (I was surprised to find that in some modes, the computer may release multiple fuel pulses per stroke to maximize swirl and burn). So there are now too many variables between the cars (.1 and .2) to assign what makes the differences, but I would love to have DFI in my car even w/o PDK, etc.
