Last year I baught a 2011 Crown Vic from government auction and I believe it came with a supercharger, is this normal? When I am in high rpm (3000+) my engine gives off an extremely high pitch whistle and it picks up very quickly, all the while draining my fuel equally fast. Does this sound like a S/C?
My car has 86000 miles.
My car has an automatic transmission.
That does not appear to be an OEM option on that vehicle and so if equipped with a supercharger, it would have to have been added. To answer your question, the application is not that common. You can determine if there is a supercharger visually (see photos on Internet for typical configurations). Regarding the noise, if there is no supercharger, you could have a vacuum leak or other malfunction in a rotating component. To have the origin of such a noise pinpointed, the recommended service is a vehicle noise diagnostic.
