Air filter shootout

Guess im good then with my dual cut out filter housing.

I wonder how it would compare to different hood setups though? For instance on my demon the hood scoops direct fresh air right near the opening in the housing, wouldnt that allow more airflow than a hood without fresh air ports even if you were running a standard open side filter?
Ram air doesn't make a huge difference. A couple hp at the most. And simulating that on a dyno is a challenge unless that dyno happens to be in a wind tunnel. The biggest effect is gonna be from the cooler, slightly denser air charge I would think.
