I have seen a few cars with the ram air hoods on them but I've never been inside one or looked close enough to figure out how the little doors in the scoops worked. I was sitting here the other day and got to wondering how that magic works? Is there a switch on the dash or a lever or something that actuates the vacuum and closes the little doors???? Thanks, Inquiring minds want to know, Armand _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.wps.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
