A centrifugal supercharger looks like the compressor part of a turbocharger,blanked off at the rear with a belt attached to a pulley.2. A roots supercharger is a far larger device,often seen nestling between the banks of V8's around the world.It is comprised of two lobed shafts and as the shaft spins,the lobes capture air,draw it into the centre of the supercharger housing and compress it between them..The only real drawback of superchargers is that they have a parasitic effect on the engine.The main benefit of the supercharger being physically attached to the engine is that there is no lag - the time between you putting your foot down and the charger spooling up to its optimum operating speed and delivering peek boost - just instant,ferocious response.The big difference comes with how much work and research goes on behind the pipework to make sure it all works properly...Finally,an intercooler is important,as it helps to lower intake temperatures..meaning you will make more power..Though its rare for a kit  not to include this.. :wink:</blockquote>
