ok, lt me try to expain it. The motor draws in air when one of the pistons in your motor starts its intake stroke the piston moves dowm in the bore and creates space in the cylinder that is filled with air. The force that makes the air fill the cylinder is atmospheric pressure. at the end of the intake stroke the intake valve shuts and traps the air in the cylinder. then the piston starts back up the cylinder on the compression stroke. at the end of the compression stroke all of the air i the cylinder has been compressed to around 9 times the atmospheric pressure(in a 9:1 compression motor). when the spark ignites the air/fuel mixture that is compressed in the top of the cylinder the piston is forced down by the explosion, which is what drives the motor. Now, if the compression stroke of the motor compresses all the air thats in the cylinder to a pressure 9 times what it was before, what if the air in the cylinder is already at a pressure many times greater than the atmospheric pressure when the compression stroke starts. Ill tell you what, you get a bigger boom on the power stroke. thats what a turbo/supercharger does, it makes the air pressure in the cylinder many times greater than it would normally be at the beginning of the compression stroke. you cant just make it easier for the motor to draw in air, you actually have to compress air into the cylinder before you will get any results. you simply cant put enoug air into a tank to do that.
