This is how it was once explained to me. Not being an engineer, It makes sense to me.
It will work, but it depends on the design and how much air your carbs will inhale.
on cars you have big ol carbs sometimes twin 1050/1150 dominators or the big demons that inhale alot of air.
The honda/Kaw/Suz ..ect ram air opening is pretty small, so there is little wasted air.
The Vmax air, although good looking and somewhat functional, will grab too much air, thus being a hinderance. As an example, take a piece of cardboard and cut a big ol hole in the center and drive down the road holding it out the window. You can feel the resistance, but it still is pretty easy to hold. This is the vehicle with the big ol carbs or monster throttle body. Now take another same size piece of cardboard and reduce the size of the hole and hold it out the window. This is similar to the smaller carb, you'll see the wind resistance is greater.
The bike can only inhale so much air, before the rest is being wasted and acting as resistance. Thats why the ram air on the sport bikes don't have a huge opening. It's about as big as some car ram air. bigger in some cases (Dodge's "Air-grabber") Next time your driving down the road, cup your hand and put it out the window, grabs alot of air.
I think if someone would build a ram air setup, that had a pressure relief valve to let the air buildup through at a certain PSI (kinda like a blow off valve, but it would be as simple as adding some exit holes) it would be more functional and not act as airbrakes at high speeds.
To me its one of those performance things your going to pay for but only see a little improvement. I think the Boxenstopp scooped faux tank, will provide a positive pressure inside the airbox, if you use the Morley kit or remove the "y" (may need air correctors though, due to the added air) and foam up the sides of the airbox/filter to seal the faux tank with the airbox.
I see your point Rebar. I've heard the comments about the fake scoops. I'm pretty sure everyone has. My favorite was as a cruise, when someone said "...Yeah, but the scoops are fake" His buddy shut him up with the quick replay "Maybe, but the bike is real and I wouldn't fuck with it."
