Also...SVO doesnt make a blower kit. So far JacksonRacing is the only to offer a supercharger for the Focus. Unfortunately the blower has some issues in that it produces very little low end contrary to what a roots blower should be doing. Adding a smaller pulley results in huge differences in boost along the rpms. One big stumbling block for forced induction on the Zetec is a returnless fuel system and no upgrades to increase fuel besides DFI systems by companies such as Haltech which cost thousands of dollars.

There are a couple of turbo Foci out in California that run about 12psi of boost and are predicted to run well into the 13s and possibly the 12s. By some miracle of god the stock motor is still hanging on under all this abuse.
