My (soon to be former) dance instructor is a big car fanatic. I have a car and it is comfortable for me to drive and I take care of it, but I view it as a tool to transport me from one location to another and I don't really spend a lot of time or money on it. In fact, I really know very little about cars and how they operate. I'm a pretty smart girl, but I just haven't had the desire to take the time to learn anything. But I found this website that explains about the audi turbocharger and the differences from a supercharger. It's really pretty interesting. Both force compressed air into the engine's cylinder, but the main difference is where it draws it's power. The supercharger has a belt connected to the engine that drives it and the turbocharger uses a little turbine in the exhaust system that spins to generate power. See, I learned something new! If I were to upgrade my car to get more power out of the engine, I'd want to add a turbo charger. Check out the turbo charger pros website to see if they can help pimp your ride.
