i'd guess 80% is from #3 and maybe 15% from #2 with the rest coming from #1

no engineers who could figure this out?
There are a lot of variables. Mainly speed. But it could be figured out in certain scenarios. Ive actually had water come up from #1 when i drive after rain or something. it almost seems like its more of an exit to keep air flowing but im sure it does suck in when that engine wants air. I have yet to take it all apart to see
