2015 HPerformance Audi TT-RS
The Audi TT RS already had a reasonably high power output of 335 hp from its 2.5 liter inline-5, or 134 hp per liter. HPerformance opted to be completely unreasonable and go for an insane 740 hp from the same engine, or 296 hp per liter.
The centerpiece of this change is a modified GTX-35 turbocharger mated with an HPerformance exhaust manifold exiting through a 90 mm Clubsport exhaust system. An intercooler with a 90 mm intake increases the turbocharger's effectiveness. Other needed changes include a modified fuel feed and high pressure fuel pump, optimized injectors, and new engine software to tie it all together.
An Audi R8 ceramics brake system was installed for best stopping performance on the track.
The total cost of all improvements is €50,000.

(from HPeformance Press Release) WORLDWIDE STRONGEST TTRS WITH 750 PS by HPERFORMANCE
HPerformance at Osterburken, Germany – a company's name that more than ever stands for pioneering spirit and development – once more crosses the known up to now 5 cylinders TFSI tuning limits by finishing of its actual project. In the past already, the team around Tobias HAEFNER caught attention by tuning of similar strong “conspecifics”, taking into account that the here presented Audi TTRS specimen with its 750 HP (= 551 kW) and 880 Nm of torque puts in the shade all ever having existed in this respect.
“Development needs time” – and so this tuned by HPerformance TTRS was not “born” over night. The progressing experience in the practice of planning and testing brought along always new findings, that – at the end – contributed to the success of the project.
Core piece of the operation was a tuned GTX-35 turbocharger, applied to an Hperformance exhaust manifold. The chilling is achieved by a company own charge air cooler, the air feed of which is guaranteed by a 90 mm air intake. Likewise known from preceding projects is the 90 mm Clubsport exhaust system. This way, the Black Hawk, as the vehicle was christened in a species-appropriate manner, develops a sound background, that does not only make goosebumps, but makes remember, furthermore, the rally ancestors in the past. The fuel feed was also modified. Besides a tuned high-pressure fuel pump, optimized injectors were installed, too, in order to warrant for the engine fuel supply. The power transmission is materialized via a spring-borne sintered metal clutch. In order to cut off the generated out of all these power components movement at any time, an Audi R8 ceramics brake system was installed. And in order to warrant for a smooth interaction of all these components, the software development partner MTR-Performance made car balancing in real time.
The total tuning costs are about 50,000 Euro. By the way, HPerformance offers this kind of car tuning, as well as the inferior tuning stage, in shape of a tuning kit. The first steps can be made by a 600 HP 9,999 Euro turbokit.
Last but not least should be mentioned that the Osterburken team has already announced to be intended to trespass this (power) range too. For more information concerning this Black Hawk TTRS please contact directly
