TTE850+ hybrid turbocharger based on the original parts of the Porsche 991 Turbo
For the production of the TTE850+ upgrade turbocharger, TTE uses special, milled compressor wheels of the latest generation made of high-strength aluminum and very thin blades. 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 wheels.
The turbine wheels are also subjected to the tried-and-tested abrasion 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 conversion from normal turbochargers to 850+ requires some parts of the turbochargers from the 991.2 Turbo-S. For this reason, the TTE hybrid chargers are slightly more expensive than if you take the Turbo-S charger as a basis.
The reinforced axial bearing ensures a higher load capacity.
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.
