TTE800 turbo 4.0 tfsi
TTE800 + hybrid turbochargers, such as those installed in the S6, RS6, S7, or Bentley Continental GT

The TTE800 + hybrid turbochargers are the first expansion stage for the already powerful 8-cylinder from Audi.

For the production of the TTE800 + 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 IHI turbine wheels 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.


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 loader is only valid if a pair of running, undamaged original loaders 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 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 executable C7 chargers or their derivatives are sent in!
