===Supercharger losses or turbocharger lag===
The benefits of using positive-displacement superchargers come with a cost due to [[Losses in electrical systems#Parasitic_loss|parasitic load]]. About 15 to 20% of the power generated by a supercharged engine is usually required to do the work of driving the supercharger, which compresses the intake charge (also known as boost). On the other hand while turbochargers aren't as high in terms of being a parasitic load, the spooling up of the turbine from the exhaust gases would result in the engine being stuck in the [[Atkinson cycle]] at lower RPM. This inconsistency could in principle be addressed with techniques like the [[Antilag_system#MGU-H|MGU-H]] that was used in [[Formula 1]] but this has never been implemented on commercial engines and much less specifically on Atkinson cycle engines.
