TT-RS gets some cool new power in the hot desert!
The Audi TT-RS is an out of the box rocket, but out here in AZ, as I'm sure in many places west of the Mississippi, the fuel is just not what the hotrod TT wants to drink. We have found that many of these cars are pulling timing due to detionation straight off the show room floor! So what we did was added a full custom meth injection system to cool the hot intake charge down and boost octane. Since we had the cooling and the octane needed to make good power; we also gave the inline five a new tune (93oct) to bump up the ponies even more. The results where grand; take a look at the dyno sheet. This was in over 102F ambent temp!!!
Huge gains in horsepower and torque, as well as a smooth power curve that pulls all the way to redline! Of course this took a bit of tuning of the HFS-4 Meth controller, allowing us to dial in the meth as needed! The HFS-4 Aquamist system is specifically designed to work with direct injected power plants, utilizing the signal from the ECU to the injectors to calculate load as well as cross referencing the pressure sensor to give the ultimate in precision meth control. Of course we didn't want to just stick another plastic bottle in the rear hatch, taking up more space, as well as putting the the meth just feet from the driver. So we engineered and fabricated a perfect fit, all inclusive, tank that bolts securely to the core support under the hood. This tank also acts as the home of the pump, flow sensor, and control valve. Taking into acount that this car is brand new, we also wanted to make a system that is easy to remove for the dealer if nessasary. Three screws and one quick line disconnect and the entire unit can be set aside. It doesn't get much easier than that!
It doesn't stop there! We needed a way to give the pilot a way to moniter the system so we custom mounted the Aquamist guage in the center pod of the AC vent leaving a gap around the unit to allow for cold air flow to unrestricted into the cabin. Those who live in hotter climates know how important that is! We even retained the ability to open or close the vent with the guage mounted! This also gives an optimal vew to the driver. The results are a 415hp, 463tq monster that pulls like a freight train!
