I may not be a magic turbo but its the next best thing. http://en.wikipedia.org/wiki/Variable_geometry_turbocharger
I dont think I could ever cut my hood but something subtle like this http://carphotos.cardomain.com/ride_images/1/1422/741/3552870004_large.jpg wouldn't be too bad. As for functionality, someone needs to do some real tests with a tunnel. But who has access to that? Most exterior mods are just for looks with little to no benefits. No need for anybody to get all bent.
