Just drop the pulley belt when you don't want it. Turbos can hurt fuel economy on some vehicles so also take that into effect. Also superchargers tend to be easier on the engine and do less wear to the engine.
A few questions:
1. If you drop the pulley, how does the air get in.
2. What are the factors that maek turbos hurt fuel economy?
3. What ways are superchargers easier on engines?
2. The turbo works by cramming more air into the engine. Without a corresponding increase in fuel injected, the air/fuel ratio goes too lean and you have detonation, which will harm engine components.
3. The supercharger is easier on the engine because they typically don't create the power a turbocharger does. That extra power tends to really tax engine components: cylinder walls, cylinder heads, crankshaft, rods, etc. It seems that OEM engine parts are built to a degree of redundancy that is acceptable for the relatively smaller power gain of superchargers, but the not the larger gain of turbochargers.
