TTE780 upgrade turbocharger for Audi 2.7l bi-turbo (S4 / RS4 B5)

The TTE780 hybrid turbochargers are the third expansion stage for the already powerful 6-cylinder from Audi.

For the production of the TTE780 upgrade turbocharger, TTE uses light, milled 7 + 7 compressor wheels. They are significantly larger than the standard parts and 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. For this purpose, a CNC turned part is used which has a larger suction than the standard part (58mm on the housing with Oring seal).

The larger turbine wheels in K16 Max contour are also clipped so that they can cope with the increased exhaust volume without generating too high 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 360 ​​° bearing used ensures a higher load capacity. The standard pressure cells of the wastegates are adapted to the new environmental conditions by equipping them with a stronger spring. Thanks to the TTE brackets, the spring rate can even be further adjusted by the owner, if this is desired or necessary.

Balancing

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 which you can trace at any time with which values ​​your turbocharger left the factory.

The price for the conversion of your series charger is only valid if a pair of working, undamaged original chargers and an original RS6 C5 turbocharger are sent. If only RS4 or only RS6 turbochargers are sent, additional costs arise. 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 approx. 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 you send us executable RS4 B5 plus RS6 C5 turbos
