As someone who has a bit of experience with turbos & superchargers, that's a no brainer. The pump, be it turbo or supercharger) is going to pump regardless of the intake provided it's been properly engineered to allow enough air past the filter at ambient temps and normal altitudes. (Many of the WW2 fighter engines overcame low flight ceilings by adding superchargers because they don't falter as do normally aspirated engines at high alts)
We did a bunch of experiments with CAI's on the SLK 15 years ago and found the only ones that worked, plumbed them from outside the engine compartment with very large bore tubing to overcome the friction losses. In the end, it just wasn't practical for those of us that wanted to remain "stock appearing". Worth at max, 2-3HP on a supercharged SLK compared to a stock airbox with a K&N installed...FWIW compared to our trucks.
If you really want increased power, the simplest, least expensive bang-for-the-buck method is by raising the boost pressures....but why?
