Is a Jackson Racing Supercharger race ver. any good? b/c I would like to bolt that on my A2 and what is a great engine internals for a SC A2. Is it the same as a turbo setup. Why I don't choose a turbo setup b/c I don't want to be like everybody else, that has an intercooler showing threw the bumper and I don't wan't to go the na setup. When you look at a supercharged car you can't see any evidence that its supercharged and it would be faster than a na setup.
