I read that the S40 2.4i engine is "naturally aspirated." What exactly does that mean? Also, I have a 2.4i and when I rev up to around 4krpm, I think I hear a slight "swoosh" kind of like a turbo. Is that the "naturally aspirated" part kicking in?

Re: (richarded)

naturally aspirated is a very nice way of saying no turbo/super charger. think about it all the T5 turbo people have NON-Naturally Aspirated engines. gee who would stoop this low and get one of those, perhaps people from the wrong side of town?
