In automobile engineering there are many kind of engines which have been manufactured by different companies but there are several problems that arise in engines like less power output,low efficiency, high altitude, mileage pick up, more fuel consumption, less torque, more exhaust etc. To overcome these problems we will try to implement supercharger in bike for getting better performance from the same engine.The main motive behind this is to enhance the performance of I.C. Engine. This project aims to modify existing supercharged engine to get a better output from it.Basically supercharger is used for increasing the density and pressure of the atmospheric air.This will lead us to get a better performance from the same engine. As we know air is non-conventional source of energy the suggested method of improving engine efficiency is economical and environment friendly. A centrifugal type of supercharger will be used because benefits of this supercharger are more compared to other types of supercharger. Benefits of centrifugal type supercharger in two wheeler is to get more power output with less emission and higher efficiency which will further result into less pickup timing.
