Now that we have compared the various factors, we can take a final look and decide. The major benefit of a supercharger is the instantaneous start-up without any lag. These are also good for any novice to install since they are low maintenance and easily attachable to the engine. These are great for smaller engines and increase the performance of high-end luxury cars. The major advantages of a turbo include the lack of mechanical load due to its drawing power from the exhaust chamber. It also reuses the waste energy and propels it back into the combustion chamber to be used. It also adds little heat to the air that gets fed into the engine. Along the lines of fuel efficiency, it is the turbocharger that proves better. Not only does it power the most heavy-duty vehicles, but it is also inexpensive to add to your small vehicle. And when you double up with a twin model, it's icing on the cake!
