Someone please correct me if I am wrong, but I thought that the method of
operation behind a turbo was as follows:

	There is a dual bladed fan with some kind of a shaft between the
	two blades. One side of the fan is inside of the exhaust manifold
	and is rotated by the exhaust of the engine. The other side is
	connected to the air intake of the carb. Therefore, when you
	accelerate, the exhaust spins the fan faster producing a higher
	flow of air into the carb which eventually makes it into the
	cylinder chamber. If you let off on the throttle, less exhaust is
	produced and therefore less boost presure.
