TTE550 hybrid turbocharger based on the original BMW N55 charger
For the production of the TTE550 upgrade turbocharger, TTE uses a special, milled 7 + 7 compressor wheel of the latest generation made of high-strength aluminum and very thin blades. Not only is it larger than the standard part, it is also equipped with the extended tip technology. It therefore promotes significantly more air mass and still responds very early. The standard compressor housing is machined with a CNC milling machine so that it can accommodate the new wheel.
The 9-blade turbine wheel undergoes the tried and tested abrasion by TTE, the so-called clipping. 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 cell of the wastegate is adapted to the new environmental conditions by equipping it 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 Sorting 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 with.

The price for the conversion of your series charger is only valid if an operational, undamaged original charger is sent. If the part sent is not suitable for conversion, you will receive a cost estimate after it has been dismantled.
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.
