yea, with a short ram could you hydro lock at a stop light in a downpour?
no. in order to hydrolock the entire filter element must become completle submerged in water. just getting the filter element wet wont hurt
ditto. think about it, you have to drive your car in reverse in drenching rain at an extremely high speed in order to soak your shortram from the reverse hoodscoop.
normal driving in rain only puts water through the normally positioned hoodscoop (which everything in your engine bay IS waterproof except your shortram). very little water is actually put into your engine bay through the reverse hoodscoop while driving in rain (foward driving = water in normal positioned hoodscoop = no water on shortram)
the really only case water can spray into your reverse hoodscoop is if you were at a standstill (parked, etc.) and in that case it will just run off the hoodscoop and harmlessly into your engine bay
in any case--hydrolock is VERY uncommon in CAI
's. and i've NEVER heard of hydrolock on a shortram under ANY conditions.
