O.S.T. Stage 2
Maximum performance at same external dimensions
longer lifetime
at an affordable fixed price
available for almost any turbocharger
up to 40 % more efficiency
If a Maximum of performance should be sheetingable also Plug and Play
A Stage 2 optimization differs to a Stage 1 optimization only in the size of the compressor wheel. That sounds simple enough, but it is quite expensive in reality. In the first step, our experts can find out which wheel dimensions on the one hand fit into the compressor housing, perfectly complementing the other to the housing and turbocharger. Some turbo upgrades are a selection of a possible part, but without much concern for the resulting performance. Since we are able to mill compressor wheels according to our specifications, we can offer the combinations that do the maximum.
The large compressorIn the Stage 2 Optimizing a compressor is selected or customized, that is larger than the standard built wheel. Which size difference arises depends on the feasibility of each turbocharger and can be inquired with us for already developed Stage 2 optimizations. The large compressor wheel is shipped of course state of the art. That is, optimized flow, with a slim hub, optimal number of buckets and Extended Tip Technology. The compressor housingTo provide the large compressor wheel enough space, the compressor housing is machined consuming process by 5 axis CNC. Contours and gap dimensions are optimized in this context, so that the new, larger air flow rate is also used optimally. The bearingAs in the case of Stage 1, the turbocharger is replaced during the optimization of the O.S.T. Stage 2 optimizing a special friction bearing, which has a special coating with the highest dry-running properties and bridge the lack of lubrication in eg cold start of the engine. Sometimes there are moments when the turbocharger not yet received the full oil pressure and the bearing is not lubricated sufficiently. This usually caused the gradual damage to the turbocharger over the term . Thanks to the O.S.T. Bearing the normal wear is significantly reduced and extends the life of your turbocharger.

The delivery time
For many turbocharger we can realize a Stage 2 optimization already within 2-4 business days. The special thing about us is that we provide not only for the optimization of best-selling turbos, but can optimize almost any turbocharger on the market. For models for which we still have no components in the offer, the development time is only 3-4 weeks.
What should be considered in the Stage 2 optimization
A Stage 2 optimization developes significant power in contrast to the standard turbocharger. Individual tuning is required in every case. Likewise, further modifications have to be made depending on the vehicle model and engine type.
The advantages of O.S.T. Stage 2
The focus of O.S.T. Stage 2 optimization is clearly on performance. In addition, of course, the lifetime is improved. Whether O.S.T. makes sense for you, you have to decide. If one or more of the following statements apply to you , O.S.T. is right for you.
I want to achieve the highest performance with my turbocharger which is sheetingable plug-n-play.
The Stage 2 optimization uses the largest possible compressor wheel while retaining the original exhaust housing and compressor housing. Thus, Plug and Play installation is feasible. In this size is the power output at the upper limit.
Chip Tuning isn't enough for me, I want to set my vehicle individually.
The air mass, which is funded at a Stage 2 optimization is much higher than that of the serial turbocharger. A custom engine tuning is required in every case. If you are planning to do so , anyway the Stage 2 is the right choice.
I want to have a durable turbocharger with more life
The O.S.T. Special bearing has a special coating on a special carrier material. Through this combination, the bearing is able to bridge short moments of a lack of lubrication. This lack of lubrication occurs inevitably at every cold start and other situations during the period of engine use. The O.S.T. bearing increases the life of your turbocharger.
