Mad Max Car

All sorts of cars use things like that as Ferrari has something similar but it's used for keeping the fans, or the a/c etc from coming on above 6,000 rpm.

It's cool as heck you can still order the Mad Max cars and get them here in any trim level you want. Last year at the track a guy had one with supercharger, the whole 9 yards and was even right hand drive. It was a kick to see it run.
