Supercharger vs turbocharger

[Duke]

can someone explain to me what the diffrence is between the two!
it sounds like they both add the same about of hp! its just that turbo delivers it earlier then a supercharger!


so can someone explain whats the diffrence!





(p.s: plz dont flame we all have to learn sometime)

OK i read about a 6 page presentation and it explained it all to me ! so i know what the diffrence is, more or less

[Duke]

and this is what the speech i guess was
http://www-unix.oit.umass.edu/~vramos/report.htm

really explains it nicely. Even tho the guy stole like everything from How stuff work web page. Compares the two so its not bad!

A turbocharger derives the energy to spin the screws providing boost from the escaping exhaust gases... the supercharger is belt driven. That is why the supercharger provides more linear boost, without the "lag" attributed to some turbos. The turbo has to have a certain amount of escaping exhaust gases, ie the engine must be revving, to spool up and provide good boost. However, since it uses energy that was otherwise being wasted (exhaust gases) the turbocharger is more efficient and provides slightly more power in most configurations. A supercharger induces some parasitic drag, but still produces a good amount of power.

Also, turbochargers generally heat up more and you want an intercooler or aftercooler to keep it at a safe operating temperature and keep the air flow cool enough to gain the most power. Superchargers generally produce less heat.

Yes but if you get lighter parts for your engine you can reduce the amount of "lag" produces.


Anyways, why is it so hard to put a turbo into an E46 M3?
