    • AWE-Tuning Audi TT-RS build including GIAC performance software flash, cat delete, exhaust, intercooler, and HRE wheels

      Here is an awesome TT-RS build from AWE-Tuning. This build is displayed well with photos of all the parts involved as well as before and after dyno's. AWE Tuning chose GIAC software boosting the power from 323 at the wheels to 351. Keep in mind the baseline is with AWE Tuning cat delete pipes, exhaust, and their front mount intercooler (FMIC). Dyno graphs, photos, and details are all below.

      The SwitchPath™ Exhaust
      We measured and re-measured to ensure that everything would have an OEM quality and fitment. Once that was done, ‘twas prototype time.




      The TT RS was determined to be a great platform for the AWE Tuning SwitchPath system. The SwitchPath system until this point had been used only on the Audi R8, but we felt that due to complaints about the tone of the TT RS in sport mode at highway speeds, a SwitchPath system with options would make a lot of sense for the TT RS.


      The difference on the TT RS system versus the R8 would be that the R8 valves on the AWE Tuning SwitchPath are triggered by throttle level, whereas the TT RS valves open based upon boost levels. Translation: This was a new SwitchPath model all together.




      The result: A new-for-the-TT RS SwitchPath system, which made the engine sing a little louder, and sound a little sweeter (and along the way, a system that lost some weight – to the tune of 9.5lbs less than the stock unit).










      The SwitchPath Activator




      While AWE Tuning’s master fabricators were prototyping the Exhaust and Cat Deletes (Cat Deletes to be covered later in this thread), AWE Tuning engineers were hard at work on the in-cabin AWE Tuning SwitchPath Activator. A new SwitchPath Activator was designed with the TT RS in mind that would enable the SwitchPath system to work independently of the Sport button.




      We envisioned a sleek control module that was not only simple to operate, but integrated elegantly within the cabin so that to the untrained eye it felt right at home.



      By placing the AWE Tuning SwitchPath Activator in the ashtray, we were able to achieve our goal of seamless cabin integration. Smoker? The AWE Tuning SwitchPath system is your reason to quit.


      So here’s the bottom line: This system is ready for business when you want it to be, and ready for a business meeting when you don’t. It’s truly the best of both worlds. And man, is that SwitchPath Activator button addictive.

      Bad news for cat lovers.
      The TT RS sounded good, but there’s a contingent that felt that another option was required. Enter the AWE Tuning Cat-Delete pipes. The best part about them, (aside from the sound and power), is that with OEM-quality fitment, the AWE Tuning Cat-Deletes can be used with the stock TT RS system.




      With the new Cat-Deletes in place, the car was strapped onto AWE Tuning’s in-house AWD mustang dyno. Max gains were seen to the tune of 11hp and 15tq, with peak gains of 7hp and 8tq.

      And some video, which is worth a million words:







      AWE Tuning Front Mount Intercooler


      While doing street and dyno logging, we noticed some nice opportunity ahead due to higher intake air temperatures than we like to see. The TT RS needed a larger Front Mounted Intercooler before it could safely and efficiently make more power.




      As you see here, the crash bar on the TT RS hangs out in a very “inopportune” location. The style of intercooler we’ve engineered for the A4, A5 and Q5 would not work on the TT RS. AWE Tuning operates at the intersection of practicality and performance – so hacking was not an option.


      The AWE Tuning engineering team was going in.
      We decided to make our Intercooler rectangular much like the stock one, but significantly thicker to improve cooling. Our final dimensions are 6 x 5.785 x 22” without including the end tanks. Translation: 80% more cooling area.


      End tanks




      Intercooler end tanks were CNC’d out of a solid block of aluminum to ensure the maximum amount of strength, smooth airflow and to guarantee no leaks.






      With the new intercooler in place, we strapped the TT RS back onto the in-house dyno for a few more pulls. Not only did we see max gains of 17hp/17tq at the crank, but we also lowered Intake Air Temperatures (IATs) by 22 °F, on stock software. This is a big push in the right direction, and will set the stage for big gains from G.I.A.C. software. When released, the AWE TT RS Front Mount Intercooler will retail for $1499.




      Wheels




      Meanwhile, HRE P40 wheels were added to the mix. Not only are they lighter than the stock wheels, but they add some distinction. We approve.


      The Flash




      With the AWE Tuning SwitchPath™ exhaust, Cat-Delete pipes, and Front Mount Intercooler now on the car, it was time for G.I.A.C. to do its thing with the TT RS. After the software was loaded, we put the TT RS back on the dyno and ran the car again. Peak gains were 33hp/45tq on 93 Octane, running G.I.A.C.’s Stage 2 programming, which is optimized for the larger intercooler.
      Recall back, the car is 360hp/367tq at the crank, stock.
      Today, we’re looking at a 415hp/419tq TT RS.


      Not only do we see respectable gains, but the G.I.A.C. software for the TT RS also allows for program switching between their 91, 93 and 100 octane files as well as Valet and Stock files through the G.I.A.C. Flashloader. The G.I.A.C. Stage 2 software is $1100.










      The Gauge


      With great power comes great responsibility. We fitted our TT RS Boost Gauge so the owner could keep track of his newly elevated boost levels. The TT RS Boost Gauge, like our other gauges, matches the interior lighting and integrates elegantly into either the driver’s side vent or any of the three center vents. All necessary hardware is included in the $199 kit.









      When the dust had settled, the TT RS had gained 55hp/52tq using strictly the parts which will be available to you…
