Could be that in the end it actually helps flow though. It's just sort of impossible to know unless you can replicate real conditions (XX mph airflow onto the whole face of the car) and actually measure the difference in airflow (MAF sensor maybe?).

Thats true. The whole time I was working on this I was thinking about how both inlets would have the same pressure being inside the nose. There could, however, be a difference in pressures at each inlet as you said. I know very little about fluid dynamics so I'm not sure how the sideways flow could affect the flow in the airbox at speed. I need a wind tunnel with a dyno inside
Like I said, I'm pretty skeptical when it comes to using the ole butt dyno. I must say though, it really doesn't feel like I've lost power anywhere. If anything, it seems a little stronger on the highway when trying to pass.
