TTE5xx upgrade turbocharger for Audi 3.0l Bi-Turbo V6 TFSi (S4)
The TTE5xx hybrid turbochargers are the first expansion stage for the already powerful 6-cylinder from Audi.

For the production of the TTE5xx upgrade turbochargers, TTE uses light, milled compressor wheels. Not only are they larger than the standard parts, they are also equipped with the extended tip technology. They therefore convey significantly more air mass and still respond very early. The standard compressor housing is machined with a CNC milling machine so that it can accommodate the new wheel.

The turbine wheels are also clipped so that they can cope with the increased exhaust gas volume without generating excessive exhaust back pressure. The ends of the turbine blades are rounded to a certain contour, which increases the throughput, reduces the load on the turbine and thus reduces the exhaust gas back pressure.


The extremely precise balance of every TTE turbocharger is a key element for longevity, sound and function, which is why TTE attaches great importance to this process. Each individual component is initially balanced at up to 2800 rpm in several levels. The trunk group is then assembled and dynamically balanced again in several levels at up to 250,000 rpm. At TTE, this process takes place on a VSR (Vibration Sortin Rig) balancing machine; each turbocharger is supplied with a balancing protocol that you can clearly assign to your TTE charger using the serial number, and that you can always see the values ​​with which your turbocharger left the factory.

The price for the conversion of your series charger is only valid if an operable, undamaged original charger is sent. If the parts sent are not suitable for conversion, you will receive a cost estimate after dismantling.

The name of the turbocharger also indicates the maximum performance! As an example, a TTE350 creates around 350 hp and a TTE350 + a little more. Often, however, further modifications to the environment, i.e. engine, intake, AGA, etc. are necessary in order to achieve this performance target. Please contact us if you have any questions, we will be happy to help.

The conversion is only possible if an executable S4 B9 Turbo is sent in
