The VMax does not have ram air. It does not produce any significant pressure in the airbox, the airbox is dust proof but not sealed for pressure. In addition ram air is only effective at very high speeds like 90+ MPH even on purpose designed systems. You could I guess call the scoops feeding the airbox a "Cold Air System" as it does draw ambient temperature air into the the intake. I think this is beneficial because a lot of heat gets trapped under the faux tank.........the top of the engine is of course right under there and coolant pipes run right next to the air box (I made my best attempt to insulate those).Please let me know how cutting two holes in the cover of the airbox is an advantage. As I see it it takes away the whole ram air effect because instead of pressure being built up and forced into the air filter it will pass right through the two holes.
Yes.I think the trumpets in the OEM airbox are the key to the midrange torque. The MBA kit pod filters allows the most air of course but the air is not streamlined or maybe better to say it doesnt develop the velocity as quickly as the trumpets, so you dont develop as much midrange torque, but do get more HP in the very high RPM ranges. Thats why MBA is best for drag racing but the modded airbox is better for everday riding where you spend 90% of your time in the 2500-4500 rpm range. Having sad that Ive never ridden a max with a OEM airbox or modded one so I cant confirm.
BUT I did replace the stock airbox on my KTM 1290R (and did all the exhaust and ECU stuff we talk about here) and the Rotty airbox had different height trumpets, which depending how short or tall they were, moved your powerband and HP/Torque numbers around a bit.
