The PDK gearbox is complete. We finally just received the car back here from GIAC literally yesterday. What we upgrade is the clutch-pack. Unfortunately the PDK is not a serviceable gearbox, so there is no way to upgrade other parts without making an entirely new gearbox. It was during the PDK software tuning that we realized there would soon be an issue with fueling, and that a larger pump was definitely required. The upper limits of its power capacity have not yet been tested, but will definitely be as soon as this new pump testing is complete. As far as when it's going to be available, I hope soon, but I honestly can't say for sure because there is still a little bit of testing to be done with the new fuel pump. From a drivability standpoint, I can tell you that our new box drives absolutely perfect!! GIAC did an amazing job with the software. Shifts are smooth, comfortable, and FAST! An important thing to mention is that our PDK upgrade will require both GIAC/Champion ECU & TCU software.

There will be a lot more updates about the PDK box coming out very soon. I just don't want to speak too soon. I'd rather wait til it's 100% before saying too much.



To date, we have complete 3 in-house builds using our 68mm VTG's on 997.1 cars. However, keep in mind that the 68mm VTG is standard upgrade on the 997.2. PDK owners can certainly upgrade to these turbos now, but without the PDK upgrade, you won't be able to go beyond about 560 wheel horsepower (without the upgraded pump). At that power level, programming gets a little dangerous because the pump starts running out of fuel. The power from the 68's on the 997.2 comes on very early with minimal lag. In fact, the area under the curve is very much like stock. See the graph below.



Right now, we're at 558 wheel horsepower and 471 lb/ft of tq on a Mustang AWD dyno. This is what we consider to be the safe level with the existing fuel pump. During the initial PDK testing a few months ago, we did achieve some higher numbers with a slightly more aggressive tune but for public release, this is what we feel would be a safe level. Below is a dyno sheet from yesterday of the upgraded PDK car. Unlike some of our other projects, this car belongs to us, so we have a little more freedom to test and experiment with it. Right now, we don't anticipate there will be a need to replace the injectors because there is plenty of room within their duty cycle. However, once the new pump is in place, we'll know for sure if they're capable of handling big power. I promise, as new developments happen, I will keep you guys up to date.





Currently, we have all of the hardware in place for our 997.2 big turbo packages. Turbos, intercoolers, headers, y-pipe, plenum, airbox, software, exhaust.....it's all readily available. The only missing link to BIG power was the PDK upgrade and fuel pump, and there's now a light at the end of that tunnel.

Another part that we've recently added to our lineup is our carbon fiber turbo inlet pipes. We've thrown out a few teaser pictures here and there of the pipes, and have installed them on all 3 (soon to be 4) of our 997.1 tiptronic 68mm turbo upgrades. What I can tell you is that these inlet pipes are CLEARLY responsible for making power. They are VERY difficult and time consuming to produce as each one is hand made using a very complicated mold. Sure, silicon hoses can squeeze in there and it's OK if they touch a water line, or get squeezed in one area, but the carbon fiber has to fit perfect. Our designers did an amazing job with these. IMPORTANT NOTE: As of right now, the turbo inlet pipes are available for .1 cars ONLY. Once we have completed the PDK pump testing and we are able to explore the upper limits of power on the PDK .2 cars, THEN we will make the inlet pipes for the .2.

Here are some pictures of the carbon turbo inlet pipes on one of our 997.1 68mm upgrade cars.



So....I hope I did OK answering some of your questions. I'm not the best sometimes when it comes to technical questions or answers. Unfortunately I can't always ask Louis to come and spend time on 6Speed because he's much more valuable back in the shop working on these projects. But, if you do have questions that I didn't answer, please feel free to ask, and I'll do my best to get the answers from him.

Thanks again for all the reps guys!! Enjoy.

My understanding is past 650 whp is where the PDK gearbox and fuel system need to start being played with.

EDIT: Wow I didn't realize how old this thread was. So what happened with this? As I understand it BBI is right now the closest to cracking this puzzle.

We've got some tricks up our sleeves as well...but I've just decided not to post about it on the forums for now.

Also why not post on forum if you found a way around the fuel and PDK issues? It may sway people from one tuner to yours if yours is the only one who can make big HP.

I know I'd like 700 crank hp if it was possible with zero issues on stock fuel and PDK.

I don't really want to post it on the forum because I don't have any finished product that I can offer. The only thing posting on the forum would do is give all our competitors a look behind the curtain. Once we're ready with something to sell...I'll post up. But I'm not sure when that will be.

As for swaying people from one tuner to ours....I think our results with the 997.2 platform already speak for themselves. To date, there is nothing out there that can compete with our (GIAC) stage 2 tune. Multiple cars in the 9's, dominant at roll racing events, and perfect reliable daily drivability...how can you go wrong?

Plus I would say having a tune that gives a lot of hp isn't enough when you guys require we pull out our ECU to send to you for a tune (as I understand it), whereas cobb sends us something to install our tune.

There are no GIAC dealers near me or I'd probably go the GIAC route, especially with the warranty it offers. But I can't go like a week without my car.

I see. Are you referring to the dealer in Steven? Or something like that. I didn't look too carefully at the city for MD. So if I get a tune from them I get the warranty as long as my CPO? Also, what do you offer in your tune that other's like EVO and Cobb do not?

What is your comparative advantage/discriminator?

More specifically, it provides coverage to our Champion Motorsport performance packages, of which the GIAC tune is often a part. It also stipulates that installation and maintenance be done at one of our authorized installation/service centers.

As for the differences between our tune and EVOMS, Cobb, or others...that's not really a question I can fairly answer, as I don't have any intricate knowledge of how their tunes are written. It wouldn't be fair for me to make that kind of detailed comparison. I can only point to the results we've had...but I also don't want to keep doing that over and over again. Well, I do...but you know...

Again not trying to be a an a$$. I've been playing in my head between a GIAC tune and Cobb tune.
