    Thank you Avalanche04. After I read your reply I dug a little deeper on the subject. As you mentioned, resonance chambers provide a way to tune the sound waves back towards the intake valve at a specific rpm where you want the engine to make it's greates amount of torque. Since sound waves travel at the speed of sound, the velocity of the intake charge gets accelerated along with the sound wave. Thus, pushing more air into the cylinder than would normally be drawn into the cyliner by action of the piston stroke alone. However, this action is limited to a rather narrow rpm range. Since engine manufactures mostly use resonance chambers to set at what rpm they want the engine to make it's maximum torque, I wonder what trade offs aftermarket air intake systems have on the powerband vs. stock and stock w/resonators removed and or altered.
