This is How Porsche's Dynamic Boost Anti-Lag System Works Without Fuel
"The air-cooled flat engine has a special place in the hearts of its fans. But emotions only tell half the story. As well as revving its way into the affections of many, the flat engine has many interesting features that give it the edge from a design point of view," reads the car maker' site.
One of those features is Porsche's Dynamic Boost, a system developed to minimize the turbo lag while increasing the throttle response of the luxury car maker's turbocharged engines. The elaborate function achieves this by keeping the throttle valve fully open when drivers release their feet from the accelerator pedal.
"As a result, there's an increased amount of airflow through the engine, minimizing the amount of boost pressure that is lost," says YouTuber Engineering Explained's video description on the impressive engine.
Jason Fenske, the popular mechanical engineer turned YouTuber host of this series, then proceeds to explain in detail how the car's dynamic boost works resulting in an anti-lag system that does not use fuel.
