by that time maybe they will finally have a different architecture - been the basic same system since the 996...

 

Looks like everybody is jumping on the DSG/PDK bandwagon, where the @#$@$ is Porsche ??

Porsche invented PDK way back, but by the time they come with it they will be the last Brand to implement it.

I remember what happened with the 2002 BMW M3 and SMG. It was hot (about 50% of folks went for it) but it did have issues and today people still like the 6sp. The system will be different in the Porsche and time will tell if it takes off like the F1 Paddle shifter did in the Ferrari or not? I am sure it will be awesome on the track! By the way nice find! I don't think I am trading in my 07 anytime soon but those are positive changes THAT SHOULD OF COME OUT WITH THE INTRODUCTION OF THE TURBO IN THE FIRST PLACE! (MINUS THE REAR cayman looking LIGHTS).

 

DSG type boxes are known for not being able to handle much torque (with the exception of the veyron). time will tell but it probably means you wont be able to mod much.

 

But I think that is exactly why Porsche has been last tot the party. They are not going to release the PDK until it can take racing abuse and then be driven to and from work every day. Also if the rumor mills are correct, PDK will be in the panamerica, which will probably be more powerful than a 997TT.

Anyway all heresay for now.

I do not agree with you on that, what about the HPA VW R32 they have an upgraded clutch and they run 575HP, up from 250 stock

I do not believe the clutch will be the problem, what I heard was that heat was an issue with the 997TT

Also as you mention the Veyron, now that was a specific (low volume) box, which is expensive, but if they would produce sufficient quantities it would be less expensive, and more then capable

Looking at other brands everybody is coming with a DSG type box in the very near future, including high TQ/HP cars

Again I think the heat is the real problem due to placement issues in the 997TT




Mike

 

the hpa r32 is a 6 speed manual, not dsg. im talking about the one that ran 202mph in germany awhile back, are you talking about another car?

 

Same car, they can make it with the DSG (with upgraded clutch) as well

See this link 2008 HPA FT575 Volkswagen R32 - Performance Road Test - Motor Trend

If they can make it work for a 575hp car (DSG) that was made for a stock 250hp I do not think we would have a problem for the 997TT

Again I read somewhere that Porsche had problems due to heat, hope they figured it out and come with it in MY09

Hello Mike,

It would be much easier to implement PDK in the lower torque, non-turbo engine, and AFAIK there is not even rumor/sighting/picture of Porsche AG testing PDK with the normally aspirated 911, right?

If that's the case, I doubt very much you will see PDK in the turbo before 2009 (MY 2010). Assuming it does come out in either 2009/2010, a couple of other issues:

1. I think it's probably not a good idea to be first generation "tester" for Porsche's first experience with this technology, especially on a monster engine like the Turbo.

2. A couple of years from now, 998 will be around the corner. Not sure if I'd like to buy a 997 Turbo with PDK when there is thought of 998 floating around.

Just speculating of course and I could be wrong, but IMO, waiting for PDK in the Turbo might be a frustrating experience.

 

You do realize Porsche first developed PDK in the 80's, right?

With this mentality, one would never buy a new car, for fear of it being replaced with a newer, better model.

 

Maybe it's because of tradition?

I liked the SMG of the M3 when it first came out - but it was **** poor to drive it cruising along the streets. Does the DSG have similar issues?

 

Hello Can

I agree waiting for the PDK could be frustrating.

As for the other points I do not agree, DSG has been succesfully implemented in the VW GTI, and is also running great on the R32 tuned by HPA (with an upgraded clutch), which is a TT with high TQ/HP

It was said that Porsche wanted to come out with PDK/DSG on the 997TT when it was introduced, the rumor was that they were experiencing heat problems.

Also PDK or DSG is just a manual gearbox, but with dual clutches that are managed by electronics, so a clutch upgrade would solve any problems, like it does with a regular manaul trans IMO, if the TQ/HP gets too high due to modding

I think it is impossible to say if Porsche has not been testing with PDK, because we have only seen exterior pics of the upcoming refreshed 997TT
It could very well have PDK, but unless we get some interior pics it will be impossible to say.

I hope they will come with it in MY09, and I would adopt it without fear, as was stated before Porsche developed PDK way back in the 80's, so it is not really "new" in that sense.

Mike

 

I have little mechanical knowledge regarding clutches, but the issue I heard was related to hollow shafts used in the gearbox. As best as I could understand there are some shafts that are hollow to allow other gear shafts within. This created a situation with respect to durability.

 

I found a couple of articles that explain the DSG in more detail

Pretty Damn Kwick: Porsche Set To Launch Dual-Clutch Gearbox, Call it PDK
<!-- google_ad_section_start -->
Straight off the editor's desk from the News That Surprises No One Department comes more info on Porsche's coming double-clutch manumatic gearbox. (That means one clutch handles the odd gears while a separate clutch toggles the evens.) According to the UK's What Car, they're calling the tranny, "Porsche Doppel Kupplungen," or PDK for short (making it as easy on the options sheet as VW's DSG). But when will it arrive, and in what models? A report from last year indicated the heirs of Ferdinand will offer the new box across all model lines. So keep your ears pointed northeast, because the noise Farago makes when the PDK shows up in a Boxster is going to make Howard Dean seem like a mute. And by shaving off a heap of milliseconds between shifts, it could mean the Tiptronic 911 Turbo's 3.4 seconds to 60 mph could be quite a laugh one day. – Jonny Lieberman
