Going deeper than 500mm

Just reading a recent post that explained in great "depth" (ha ha) that in a 2.4 puma, you cant go deeper than 500mm which suprised me. I have a RAI which is sealed on the bodywork. But, the question is what else do i need to do. I see all these you tube pics showing water coming over the bonnet, what mods have they done. BTW i have wading blanket over the grill.

I think the 500mm depth is a sort of 'max definitely safe' limit...

Above that if you're stationary you could run into problems with electric fan, electric throttle etc but if you push a now wave if say you're safe up to the wing air intake at least, I wouldn't take mine any deeper

Certainly you see pumas with footwells full of water keep going, but I wouldn't want to put the throttle underwater for sure!

As a general rule for myself , I try and keep the sills out of the water but I've seen much deeper. Also you'll throw water around the engine bay at depths where the sump is underwater Cheers, David

See here for some fairly deep wading by a 110 and some other vehicles- puma opens doors to let water out but had no problems...

I could not readily find the video of the Royal Marine standing up to drive a Defender through deep sea water from a landing craft.

However there is this one

Personally I try to avoid sea water as much as possible!

Bigger wheels and a lift kit would increase the safe wading depth. http://defender90xs.blogspot.co.uk/

looking at that, although he may have a RAI, it can't be good having a dash full of water with a puma! his heater intake etc were all underwater and seeing the water pouring out from behind the dash makes my skin crawl! Cheers, David

...or might be worse if they allow vehicle to float or even just reduces weight/traction on underwater surface?

If you go to 38/15.5/15 wheels then it may be an issue, but you could increase wading depth by a couple of inches by going to something like a 265/65R18. Using larger rims means you get a bigger diameter without displacing too much extra air.
A lift will have the opposite effect, reducing buoyancy at any given depth since less of the body will be submerged.
It won't turn the vehicle in to a submarine, but it could give you the ability to go 6 inches deeper before your feet get wet. On the down side, it will restrict the number of car parks you can use. http://defender90xs.blogspot.co.uk/

think about extending the breathers for mech components and tank too, plus ECU locations,

engine - bulkhead
ABS - under drivers seat
DPF - under drivers seat

td5 - ECU under seat

pre tdi - less electrical bits to worry about Cheers
