Today for our iMoformation session we will be looking at Twin Scroll Turbochargers. It is probably one of the more complex forms of boosting the engines output due to the fact that the exhaust gases are split based on the cylinder configuration. It is one of the many configurations used to boost the performance and efficiency of cars. Twin Scroll Turbochargers allow the engine to utilize exhaust gas effectively at both low and high RPMs by combining the exhaust gases of cylinders that move in synchronization. The process of combining the exhaust gases and splitting the output to the turbos, create a higher pressure output that in turn boost the performance of the turbo. On a Twin Scroll Turbocharger, the A/R ratio can be affected by utilizing various Vanes which determine the amount of air flow into the turbo. For a clearer understanding of how the system works, see the very descriptive video below hosted by Jason Fenske of Engineering Explained.
