Are there any kits for the focus (zetec) that use a centifugal supercharger instead of the traditional top mount with a modified intake? If there was enough room in the bay it would seem like a better option in that it is easier to install and after or intercool.
I know that the honda gang has been using a design that uses a shafted model in order to put the charger on the least crowded end of the engine bay for many years now.
