19. The LSA engine uses a supercharger to compress the air charge into the engine, but this can increase the temperature of the charge, so a water-to-air charge air cooler is used after the supercharger to cool the air, making it denser for more power. The charge air cooler system uses coolant (separate from the engine cooling system) that flows through a reservoir (background) and a small Edelbrock heat exchanger. The heat exchanger mounts in front of the radiator and is cooled by airflow into the engine bay.
