ok so i have a slight opinoin on going supercharger for your car......my idea of it is a supercharger takes engine hp to make boost and since our cars dont exactly put that much hp down i mean mabey not a awsome idea but it is your car.......turbo takes no power to make boost lol.......just my little input
the focussport supercharger kit is a good kit but you will see an increase of about 60-70 hp to the wheels, it doesnt put out much psi and is basically a tuner kit. if you want a supercharger for your zetec look into the jrsc w/ bbk upgrade and big boost kit. that is about the same price and is used a lot more around here than the focussport one. Superchargers are great, they require little to no maintenance and will give you instant power with very little lag if any. so my advice is look for the JRSC kit.
