both are expensive........

and different types cost idfferent amounts.....

from gambits link, i get the impression superchargers are a lot more expensive

depends what you want, as said above a supercharger will work off the engine, whereas a turbo uses exhaust gases to turn a turbine.

Turbos therefore have a lag time before the turbine spools up and forces the air, superchargers give instant forced induction

Oh Cdcool, different engines are more suited to each....

how does the cost of fitting compare?

turbo vs supercharger

That's debatable gambit :lol:

all u need to know is that it operates the same as a turbo i.e. forced induction, except whereas a turbo is driven by exhaust gases the supercharger is belt driven

and the whine of a supercharger is far nicer than the noise from a turbo

do you see similar, better or worse performance increases from superchargers or turbos?

In leymans terms it's a fan on the inlet manifold pumping dense cold air into the engine along with fuel, fuel explodes more and quicker and it in turn makes the engine stroke quicker and your car faster, only main down side is that it is 'run' by the engine so it uses more fuel to power it iirc

There's different types, read an article on them sumwhere a few weeks back...

There's a screw one, and 2 others :lol:

Some have more components than others and some work higher up the rev range than others, thats all I remebered, how worth while was it me reading that :lol:

A supercharger is a positive displacement pump. Its purpose is to increase air pressure and density in the intake manifold. It does this by pumping more air than the engine would use without a supercharger. The supercharger is matched to the engine by its displacement and belt ratio, and can provide excess airflow at any engine speed. This concentrated charge of air provided by the supercharger results in a more powerful combustion stroke in the engine's cylinders, resulting in improved performance over non-supercharged vehicles.

A supercharger is connected directly to the crankshaft by a belt unlike a turbocharger which is driven by exhaust gases. An Eaton supercharger provides improved horsepower and torque, at lower engine rpm's, by pumping extra air into the engine in direct relationship to crankshaft speed. The positive connection yields instant response, in contrast to turbochargers, which must overcome inertia and spin up to speed as the flow of exhaust gas increases. The supercharger is a way to get around "turbo lag". The
lubrication system also differs, in that, the supercharger is self-contained whereas the turbocharger requires engine oil. The end result is a highly reliable system with instantaneous throttle response.

basically, what is it? how does it work? or does anyone know any web sites that explain them?
