I doubt it could ever really be a true ram air setup as the air from the inlet merely enters the air box. It has to make a turn to get sucked into the stacks. More air is always good, but what's the problem you're trying to solve?

But there's no defined path for the air to reach the stacks; it's just open space within the airbox. Pic, airbox top off.
