TTE475 hybrid turbocharger based on the IS38 for Golf 7 Gti & R, Leon Cupra, Audi S1/S3 and many other EA888 Gen3 models
For the production of the TTE475 upgrade turbocharger, TTE uses a special, milled 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 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 original Borg Warner turbine wheel is also replaced with a light, modern wheel with the latest geometry including a reinforced rotor, and it is also given the tried-and-tested finish by TTE, the so-called clipping. 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 series-installed muffler on the compressor housing is removed to improve flow and replaced with a CNC-milled part. This measure not only improves the flow behavior of the compressed air, it also changes the sound of your new turbocharger and extends the surge limit of the charger.
The 360° bearing used ensures a higher resilience. The standard pressure cell of the wastegate is 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.
