Right about the suspension, wrong about the blowers. Superchargers depend on what type you pick. A positive displacement blower will bring on the power early but won't pull as hard up top as a centrifugal or a turbo will. A centrifugal supercharger is basically a belt driven turbo and will come on in the higher RPMs and keep on pulling. Superchargers take power to make power though, you have to deal with belt slip but they are simple. A properly selected
turbo setup, on the other hand, will come into boost pretty early, not run out of steam up top and uses very little power to make its power seeing as it is just wasted exhaust gas. Also no belt slip. They are a more complicated install though but with so many kits out nowadays its not nearly as bad as it once was.
IMHO, PD blower for a manual street car, centrifugal blower for a stick shift weekend warrior or 1/4 car and a turbo setup for any automatic. Autos are turbos are like peas and carrots.
