A New Type Of Turbocharger!
Variable Geometry Turbochargers and Twin Scroll Turbochargers each have their own unique advantages, but what if you could combine the technology together? Borgwarner has developed a turbocharger concept where a twin scroll turbocharger has a valve which can redirect exhaust airflow into just a single scroll, or vary the amount the valve opens and allow for the gases to completely split between the two scrolls.

I love your videos!
I’d like to know something: Are you a mechanical engineer?
This seems a lot like what is in the turbo bmw models. How wrong am i?
Holy cow that sounds amazing! Is this already used in some cars? Or not yet?
Wow!!! road&track magazine featured your explanation on their home page too…

Good going Jason!!!!
I have a question about back pressure on these variable twin scroll turbos. One of the main benefits of the twin scroll turbo is avoiding back pressure on overlapping exhaust valves. Won’t this be negated by effectively switching all cylinders into one exhaust housing?
