A supercharger sits on top of the intake and is run by a belt.

Turbo sits wherever you want, and is run by the exhaust.

That's the only difference really. Both of them just compress air.

In some cases you can put a SC or Turbo on an engine without hurting it, but it most, you need to modify the engine so it can withstand the extra abuse it's going to recieve from it (ie, stronger rods and a stronger crank)

What do you mean multiples? As in a supercharger AND a turbo? or twin SC's/twin Turbos?

I've never heard of anyone putting both a supercharger and a turbo on an engine.

I've never heard of twin superchargers mainly because it's run by a belt, there's no need for two.

Twin Turbos are available, generally one turbo is samller than the other and is used to fire up the second bigger turbo. Any time you see "TT" on the back of a vehicle, generally it means "Twin Turbo". Audi's use a lot of them, and so does Nissan on their 350's.

The benefeits are a much higher power/weight ratio. Instead of dropping a 700lbs V8 in your vehicle, now you can drop a 300lbs I4 in and slap a turbo on and get the same power as that V8, but lose a lot of weight. But it punishes the engine more, so it won't last as long generally as an N/A engine.

So these aren't superchargers because they're not "on top of the intake"? Have I got that right or is someone else confused? That's okay, we already know the answer.

Not a problem as long as you drive conservatively and keep the engine tuned, cooled and oiled.

For US$3k you could turbo 4 cars if you look hard enough for the parts and DIY.

the purpose of the intercoller is to cool the charge of hair going into the engine to make it denser, not really to cool the engine. a turbo would take a bit longer to spool up and u probly wont get as much off the bottom end from a standstill. since a supercharger is belt driven, id have better response, but take a little power off the engine since it is directly connected.

Another question.. I suppose that when I get turbo or super don't I have to think about changing transmision to better ,and all little parts in the engine because turbo will give too much power for regular components that were there already?

If you are talking about putting a turbo on an import the tranny willl at least need some work and a back up one is a good idea. Fast and Furious did not show all the kiddies that little thing, however it is reality and very expensive. On the other hand a supercharger will require a lower end beef up and a tranny upgrade. A supercharger will give you more immediate power on low end and a turbo kicks in at higher RPMs and actually better fuel economy because it is not always engaged.

Too much torque can break a tranny? How?

Lots of import trannys are made with some aluminum internals which if not aircraft grade are not all that strong and don't hold up to torque or to pounding too well, in addition to having thinner clutch bands and in general smaller parts to save on overall weight and spinning mass.
