compare to turbocharger, supercharger don't have lag, as i'm told, like the turbocharger will. this is because supercharger is running on belt, which mean the power is constant. Unlike the turbo, supercharger would start to pump air as soon as the engine is started, or normally at 1500rpm. Becasue you don't feel turbo lag like engine with the siput have, driving a supercharged car will fill like driving a car with a bigger engine.


turbocharge however, you won't feel the power if you only run your car most of the time under 2500rpm (like my dad, shift at 2000-2500rpm). Depend on the size of the turbine, some of them the boost will come quite early at 2000+rpm but some might need you to rev until 4000rpm. When the boost kick in, you will feel a sudden increase in g-force and the car feel damn more powerfull. i never drive one but i sit in some before.


another thing i know by reading some article online, and from some sifoo here in ZTH, is that there isn't too much thing you can do about the respondsiveness of a supercharged engine. changing to lightened flywheel won't do much good because the supercharger will still slow down the engine. ceremic coated gze piston is also a plus! since ceremic don't absorb heat well (i think), more power would be transfer to the turbocharger (if you dump the supercharger for the snail).


more than that about supercharger vs turbocharger is general information on automotive. can be easily find on the web. and thats pretty much all i know, more of that you have to page all the sifoo master in the forum already.
