One of the oldest and most common ways to make a little engine do big things is to use boost from a turbocharger or supercharger. Why bother? Why not use a big V8 instead? Well....V8's need a lot of room to fit. You'll never get a V8 under the hood of a WRX or a small Volkswagen. No, that's like trying to park a Hummer in a grocery cart return- both fun ideas but unlikely to work. To fit a V8, the car itself needs to be larger- and we all know that little cars with big power are huge fun.
