Hi Patrick.
Google cylinder wall air drag (intake tubes to airbox vs. carb venture cylinder drag). Interesting in that intake area is not all there is to air passage into an airbox.
Google intake airbox design (size and shape effect a<span style=”font-family: Calibri;”><span style=”color: #000000;”>coustic </span></span><span style=”color: #000000; font-family: Times New Roman;”>pre</span>ssure timing affects).
Karting air filters have incredibly large filtering surface area. No other asphalt-based motorsport that I’m aware of has such large filters. If maintained, are they necessary? I’d like to see real comparable data on this. I’ve tested with large and small filters on George Banke’s dynamometer (back to back in 2001 on modified CR 125) and found no difference.
Great info out there. Focus on reading technical information, not opinion, hearsay and grapevine views.
As is often the case YMMV.
