Nice drawing, I wondered how it worked. If you look around you will see the
principal quite often on louver blades.
One issue, is it required ie, what volume of rain would need to be taken in
case problems and what would those problems be? Also doesn=92t the air
filter usually incorporate a drop-out for water.
(Finally =96 some motorcyclists with old classic bikes say they get more power
from engines in the damp, better compression?)
All theoretical for me, don=92t fancy getting my 2F petrol in deep enough to
need a snorkel (famous last words?).

Hi Brian,
Sorry for the shockingly slow reply I can't find the part number but it is
the common garden variety Donaldson truck ram but some people don't realise
how it works in relation to shedding rain. I have added a pic to explain.
On a 4" ram the pipe slips up inside it about 4" the rain is much denser
than air so it will not turn a corner easily so it fly's straight to the
back wall of the ram and dribbles down the sides and runs out the slots
while the less dense air travels into the snorkel pipe. That is why the ram
top is intended to be vertical sometimes you see the ram on homemade
snorkels parallel to the A-pillar then they won't work properly as far as
sheeding rain.
Diesels love the pressure fed air but some petrol engines engine management
can get confused when pressure fed via big snorkel.
Cheers,
Craig.
