TTE1020 EA825 4.0TFSI Turbo

TTE1020 EA825 Hybrid such as in the RS6, RSQ8, Porsche Panamera, Lamborghini Urus

The TTE1020 hybrid turbochargers are the second expansion stage for the already powerful 8-cylinder from Audi.

For the production of the TTE1020 upgrade turbocharger, TTE uses light, milled compressor wheels. Not only are they larger than the series parts, they are also equipped with extended tip technology. They therefore promote significantly more air mass and still respond very early. The standard compressor housings are machined with a CNC milling machine so that they can accommodate the new wheel.

The large 9-blade turbine wheels are also clipped so that they can handle the increased exhaust volume without generating excessive exhaust back pressure. The ends of the turbine blades are rounded off to a specific contour, which increases throughput, reduces the load on the turbine and thus reduces exhaust back pressure.

The 360° bearing used ensures a higher resilience. The standard pressure cells of the wastegates are adapted to the new environmental conditions by being equipped with a stronger spring. With 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 each TTE turbocharger is a key element for the longevity, the sound and the function, which is why TTE attaches great importance to this process. Each individual component is initially balanced in several levels at up to 2800 rpm. The core group is then assembled and balanced dynamically, again on several levels at up to 250,000 rpm. At TTE, this process takes place on a VSR (Vibration Sorting Rig) balancing machine. Each turbocharger is accompanied by a balancing protocol, which you can use the serial number to clearly assign to your TTE charger, and which you can trace at any time with which values ​​your turbocharger left the factory.
