Dyno and tweaks

[C43]

No offence taken...I believe in accepting criticism as much as I give it. Nevertheless, if air filters were 100% effective in the manner intended to perform, racing teams around the world would not be using high flow filters..just cheap ones. The point here you see is the one of economic viability and when manufactured to a cost for a mass market purchase then costs are kept down to entice customers with a certain level of set affordability. Thats the economics...which goes on to explain why machines like Ducati's come with KingDragon filters..a K&N alternative, because they are higher priced and allow for the good gear. And maybe your friend has got more experience with Suzuki's and not to take away his know how nor his expertise but an internal combustion motor is an internal combustion motor and they ALL work the same! Fact is fact...around the world..performance filters are used over stock OEM ones (which is not to say that the OEM filter on the Busa is no good..just not great). And you know what, if the Boss has had 6 months experience with The Hayabusa and he has managed to figure out the ins and outs, kudos to him for he has succeeded where others have not and it shows that its not just time but resourcefulness and ingenuity that allows engineering to develop and advance our lifestyles. A better filter gives better performance, its as simple as that (and its not always HP....). Flow rate is an involving subject which is supported by thermodynamics (which incidentally I majored in University for my Grad dip). there are facts that I will certainly concede to me not knowing but this is not one of them....
