What is a hybrid turbocharger? [management]

A term often used in engine modifications has nothing to do with hybrid vehicles. However, there is a significant relationship in tuning and power increase by changing the boost, but without major mechanical modifications. 

A hybrid turbocharger is nothing more than a modified factory turbocharger - in such a way that it fits the original exhaust manifold mount, but provides different (known to be better) performance. Thus, tuning by installing a hybrid turbocharger is quite limited in terms of mechanical improvements, because only the turbocharger and some elements of the intake system are subject to them.

Why a hybrid?

A factory turbocharger is always designed with two opposing goals in mind: performance and economy or driving comfort. So it's always the result of a compromise. The hybrid turbocharger is designed to enhance vehicle dynamics even at the expense of ride comfort and economy.

How does a hybrid turbocharger work?

Most often, it is formed through a combination of parts of two turbochargers of different sizes. The part responsible for the compression (compressor) comes from a larger turbocharger, and the part responsible for driving the compression wheel (turbine) is factory made to fit under the factory support. However, this part can also be modified to improve performance. It is assumed that then larger turbine rotor, no external changes to the case. Inside, the casing is cut to a larger diameter to accommodate the larger turbine rotor. Without this modification, the turbocharger - only with a larger compressor rotor - would be more efficient, but the rotor would create more inertia, which would mean an increase in the so-called efficiency. turbo circles.

The term "hybrid turbocharger" is also used in relation to Changes in turbocharger controlwhich did not need modification. Then, instead of electronic, vacuum control is most often used.

Why a hybrid?

While building a hybrid turbocharger seems like a complex process, the actual setup of the turbocharger setup and engine tuning is simpler than installing a different, larger turbocharger. A well-built hybrid fits not only the original exhaust manifold, but also the lubrication system. The fewer modifications in this respect, the less the risk of “missing” the modifications. So it can be said that a hybrid turbocharger is something of a cheap tuning or half measure, which does not mean that it produces bad results.

Who manufactures hybrid turbochargers?

The construction of "hybrids" is most often carried out by companies involved in the regeneration of turbochargers. To order such a turbocharger, you need to find a factory that has experience with a particular type of not only a turbocharger, but also an engine. Once it's installed in the car, the rest is up to the tuner, who has to tune the engine to the new turbocharger. The best effect is obtained after preparing a completely new map.
