Those CAI systems are great for NA applications, but do more harm than good on a supercharged setup. The taper to the larger diameter drops the air velocity, raising the pressure the throttle body "sees." High pressure and low velocity are what the throttle body thrives on. Because the blower does heat the incoming air, the engine no longer sees the benefits of the CAI system. Simply put, velocity helps NA engines fill the cylinders, and the losses that come from the additional suction required to pull air through a long tube is overcome by this. Once the air is moving, it has momentum and this helps "push" it into the cylinders. On a blown engine, velocity does NOT help fill the cylinders. There are rotors there. All velocity does is make the air less dense, and this means less efficient air compression.

Could I cut my CAI to a short ram? Where exactly should the filter end up after I do? ANYBODY PUTTING THEIR MONEY ON AN SAFC?
