I would say that the turbocharger is the best way to go, becuase it uses exhaust gases to power it , as opposed to a supercharger which uses pullies and will result in a parasitic power drain... Turbos can be modified to result in less lag and still impressive power gains...superchargers, IMO, should stay on cars that dont see high revs because thats where they shine...low end power... but if you own an import that revs higher than id say 8k rpms go with a a turbo because you will get awesome power from around 4k rpms (depending on the type of turbo you get) till redline. Keep in mind...maximum power output isnt always the most important aspect when buying a turbo. Spool time, your redline, turbo lag and other things come into play here, and most manfacturers will work with you to come up with the best turbo for your car. lemmie know if i am wrong about something...im sick and prescription drugs make me woozy
