WARNING: This post has educational information, skip to bottom if you don't care.
here;s what I know about Turbo's and superchargers and it's pretty correct to my knowledge.
Turbo's: will make more top end power and have a higher peak output than a supercharger because, since Turbo's are not in anyway linked to the engine revs they can spin faster than the engine actually is pushing more air into the engine and with proper tuning will create more TOP end power than a supercharger.
Superchargers: Being belt driven off of the crankshaft the supercharger has a rev limit equal to that of the engine. That being said, because of this belt drive they have more LOW end power than Turbo's produce because they do not need to wait to spool, but will not gain as much Top end power.
Both Turbo's and Supercharger's have there places and certain engines lean towards certain types of forced induction. Superchargers will produce more LOW end power can allow you to have quicker 0-60 times because of an increase in torque in the lower powerband, while turbo's will give you more TOP end power and a higher Top speed along with improved 0-60's
Now as technology progresses and Turbo's implement things like VVT (variable vain technology), lighter alloy's, ball bearings, etc, the spool time is getting less and less the larger the turbo gets, but as said before the engine and application of what you want to do can be the deciding factor in if you want to turbo or supercharge your car in the forced induction route.
then there is also the dying art of N/A engines.
And my perfect car would have to be about 5 different cars because you can't create one car that satisfies every need.
the list would look something like this
DD - B5 RS4 (modified)
race - Dahlback Quattro
OFF Road- Hummer H1 Alpha (moded by Banks)
Fun - Lamborghini Murcielago LP640 be Hamann
Fun (2) - 1970 Hemi 'Cuda
Fun (3) - Ferrari F40
Fun (4) - McLaren F1 LM
