Hybrid_From_Hell Posted November 12, 2016 Share Posted November 12, 2016 Righty Ho. In the huge rebuild of the 90 following a electrical fire which did major damage I have had the 90 stripped to the bulkhead both sides, and in the process spotted the heater was 98% full of solids LOL So, having stripped that new core (as the mud clear meant it then was free to leak ) I looked the the issue that the wing vent when one goes playing "Submarines" allows water to enter "Rapidly"....and then pours through into the passenger can area ....lol Even worse are the after market "Forward Facing Ram scoop" types, will be like a supercharged funnel Anyone seen REAR facing (ie where the opening on the wing top vents are on the bulkhead side) vs front facing ? If so can you link / post up who makes them, otherwise its another job to fix on the list ! Nige Quote Link to comment Share on other sites More sharing options...
Snagger Posted November 12, 2016 Share Posted November 12, 2016 If you plan on more wading, then wing top snorkel would be a better option. Quote Link to comment Share on other sites More sharing options...

Arjan Posted November 12, 2016 Share Posted November 12, 2016 If you take the LHD version it will fit rear facing.. However - a snorkel could be a consideration.. Quote Link to comment Share on other sites More sharing options...
mmgemini Posted November 12, 2016 Share Posted November 12, 2016 I think the suggestion of a snorkel could be best. If you go rear facing, think of the Camm theory although I don't think you;ll be going fast enough for that to be taken into consideration.

mad_pete Posted November 12, 2016 Share Posted November 12, 2016 Can't you make some sort of cover/adopter for it and screw a jam jar lid on before swimming ? Quote Link to comment Share on other sites More sharing options...
Disco-Ron Posted November 12, 2016 Share Posted November 12, 2016 I had southdown snorkel on my 300. .. drivers side for engine and passenger side for heater.... I made a plate for the wing top and put a pipe from that backwards with a piece of flexi from that to the pope up the screen frame.....

muddy Posted November 13, 2016 Share Posted November 13, 2016 Why not buy a fancy boy racer ram air jobby and cut it off and spin round to try it? Quote Link to comment Share on other sites More sharing options...
GW8IZR Posted November 13, 2016 Share Posted November 13, 2016 warning geek alert! :-) in a previous life I had to do wind loading calculations for antennas, one thing that always took engineers by surprise were mesh dishes. In simplistic terms, above a certain air speed meshes behave like a solid sheet and in general the smaller the hole the lower the speed. The ones you see on the bay have quite small holes and even at LR road speeds they will not behave how you might expect. As it happens just this week I stuck a bilge blower in my heater and before I put the screws back in, the cheapo plastic ram cover that was on my heater was actually being sucked onto the vent - a serious restriction. ( I just put a few 25mm holes in it till my proper vent cover arrives ) HTH Quote Link to comment Share on other sites More sharing options...
