I've actually answered my own question on this - I traded my modded 2010 turbo for a turbo S and I haven't done any mods yet I can say without question that my old car was faster and pulled harder. So now I'm in the situation of modding the turbo S to make me happy. I would suggest to anyone on the fence to just buy the standard turbo - I certainly don't see where the extra cost went. To the OP - you can install a full upgrade kit from techart or FVD which will switch the turbos to larger ones and these kits are producing around 700 hp. They're not cheap - $25000 - but understanding your goal you would be better buying a turbo and dumping the extra $25,000 into those kits then dumping it into a turbo S which really doesn't give you anything more for the money

 

One way of possibly finding out is getting your PTTS turbo impeller Porsche part# from your dealer. Then get a VIN# from PTT and get that turbo impeller part# too to see if they match.


Great info thanks! That is definitely an option depending on how bad that lag is.

 

My Panamera has the Fabspeed downpipes and Evoms tune. All I can say is if the difference is barely perceptible stock PTT to stock PTTS, then the tune and downpipe mod is a big difference as it is VERY noticeable. My car stock had a tiny bit of lag and the tune made the power much more linear, not to mention beastly, when the foot is to the floor. I wouldn't just do a tune as the downpipes probably helped quite a bit as well.

 

We've done some custom options for cars with plenums and secondary cat removals. There aren't a great deal of hardware options for these vehicles.

 

Austin - how do you guys handle programming the ecu - my previous PTT had the FVD ecu installed and I was pleased with it but im not excited about being without the car for a week while I ship the ecu to germany. Also with my current PTTS if i were to install fabspeed downpipes, an x pipe with the factory sports exhaust and the ipd plenum what type of tune could you install and what type of gains could I expect

 

You do not need to send ECU anywhere but ANY GIAC supplier near you, it's almost instant as long as you pay for overnight. They will get it out the same they receive it, even FVD is like that now. With the Fab DP's you should look at another 25-30HP's on top of the circa 90 from the tune. The IPD does not add more than 10 even after a tune, but hey 10 are 10. Nonetheless pretty impressive considering it will be less than $7K.

 

FVD does turn it around in a day but they don't program in the states so it has to ship to germany and that takes 2 days there and 2 days back even with expedited shipping. Regarding the IPD plenum - I was under the impression that it delivered around 25hp - at least that what they claim on their site (any one have any proof/experience with this?) I also know I won't get 90hp out of a tune since my car starts with 50hp more so just trying to get a real idea as to what I can expect. I'm guessing once I dump the money into it, it will drive very similar to what my modded PTT did and that's why I suggested to the original poster not to waste the extra cash on a turbo S when the reality is you get very little substance for a big chunk of coin.

 

There is so much to say about the plenum, but think about it don't go by what they claim as I can claim many things as well...

If you are NOT increasing your intake volume, and all you are doing is smoothing the air coming in so there is less turbulence, do you think you are getting a lot of power from air velocity?

I have read and read and read about tests, and there all inconclusive. It's only $900 and the cheapest mod you can make, at least it's a mindf&$@ at worst.

 

Because the Turbo S models are power kit cars, you get a similar gain from our software compared to what we make on the Turbo. If others are making only 25hp, there are likely torque limiters that they're unable to find. Having driven both, the modded Turbo S models are definitely more potent.

 

As stated previously, the DMEs must come to GIAC, however, we can turn them around very quickly. If the DME comes early delivery, it can be shipped back out the same day in many cases. The only thing that might delay that is if there is a new file revision in the DME that we need to read out and make a new calibration from.

 

+1, I have it and concur. I even added the BMC filters. The GIAC programming with the FS downpipe w/sport cats make the primary gains.

 

Austin - so the DME has to go to califonia or can one of your local dealers install the software? There is one about 15 minutes from me and if I could drive there, get it programmed and drive off that would be pretty tempting.

 

Unfortunately, it would need to be sent here for the time being.

 

NelsonF is right - Porsche replaced the titanium alloy turbine wheels with the standard turbine wheels from the CTT/PTT turbos. It is expressly written in a letter PNA sent to the US NHTSA.

 

This is what I suspected after owning one of each I see/feel no difference between the two from a performance standpoint. Guess I fell into the Porsche Hype and stepped up to the Turbo S for no significant reason. This is why my advice to the OP was to save the money and buy a turbo then dump it into go fast goodies instead!
