With the 997.2 turbo due within 60 days, some have suggested that the PDK torque limit will be around 790nm.
does it mean that the PDK can handle power Reliably up to 790nm? or that 790nm is the absolute limit for the PDK, and anything higher would destory the gearbox?
hopefully it's the latter, and some tuning on the 997.2 turbo is still possible without messing around with the gear box....

I have an Mitsubishi Evo X with Dual clutch gearbox. Standard power&tq is 280HP&422Nm. Even in stock when I dyno, there is some slip detected in power&torque graph (drop in power&tq around 5000rpm), and I can feel a little slip during driving, also once overheat warning after 1 hour hard driving (lots of WOT) on the freeway.
Later I tuned it (racing cat, reflash, intercooler, K&N) to around 360HP&530Nm, during hard highway driving the overheat comes many times during a month, and the last time it goes to limp mode, CEL appears and shift is very jerky. I have to reset the ECU and change the TC-SST Oil (Twin Clutch - Super Sport Transmission). Then I install oil transmission cooler in front of stock one. I never get any overheat or limp mode since.
Then I tuned it again (fine tuning, changing cams and exhaust, but still standard turbo), around 450HP&620Nm. It goes to limp mode (CEL) again. I plan to install 1 more oil cooler and circulating pump. Before I installed it ,I never use it in highway again, afraid the limp mode comes again. I only use it in town (you can not do a lot WOT in town due to traffic).
I bought the Evo's because it is easily modified, the motor (with garret it can be 1000HP), I think I should bought a manual tranny instead.
Have a CLS55 AMG (800Nm) never has problem, I believe it use the same 5speed auto as Porsche Tip.
Until the turbo's PDK proved to handle heavy modified, I won't buy it.
Your not going to get 1000hp from the new 4B11 engine without MAJOR machine work, it was the old 4G63 motor that could make those numbers..
As for the DCT, I think it takes a couple of tries to get everything right, Gen 1 Nissan GTR would blow gearboxes after moderate abuse. Evo X are not blowing as often. Give them 2 more years and all the bugs will be worked out.
hangon guys... We are in porsche 997tt forum lol...
As PDK box is so new,I doubt that tuners can easliy do any upgrade like they done to tip box..So it might be a trouble at the first 1-2 years.You gonne give tuner times to improve their parts and skills for 997tt.2.Should buy used one at least 1 year after release if you want big power.

I agree, the PDK will not be easily or inexpensively upgraded.
The PDK will be better for stock, but after that, for big hp applications, it will likely be a headache like all the rest of the dual clutch trannies.

How many coupes did Porsche sell last month ? 15 ? Even the used 997tt's seem to sit on dealership lots .
So does PDK plus the 20 more hp with this Dfi engine impress ? Well it would have to sell more than 15 cars a month .
As for tuning potential . What tuner is going to spend time and money into reasearch and development of aftermaket enhancements when thse cars simply are not selling?
Add to this some of the problems being discussed on the 997 forum with oil consuption on Dfi engines it almost seems like PDK is the least to be concerned about .
Similar arguments have been had for each generation of 911, simply put, tuners will 'find a way'.
But to the OP, who says the PDK Turbo is a few months out? It shocked the $hit out of me they changed the nav in the turbo prior to a facelift nevermind a whole new engine and transmission 3 or 4 years in.

An official word would be helpful. The dealer I spoke with was very closed-lipped about the arrival of the 997.2 Turbo. No doubt because of the three 2009 997 Turbos he already had on the lot.
