Aqua dynamics

Just been for a drive into Cirencester and came across a wee bit of
water.
The dual carriageway underpass by the house has around 4ft of water in
it and after driving through it on the way out saw my neighbour tow a
Passat out on my return (I still made it OK ;-)
Anyway, has anyone worked out why it is with an LC, particularly the
lifted ones, that when you go through any water more than a couple of
inches deep at speed it ends up over the windscreen?
I don't know what causes it but it does slow down a good puddle bashing
session ;-)

Hi Julian
I know what you mean living here we get our fair share of the wet stuff.
I think its because the water can actually spray up because of the extra gap
at the front of the cruiser and then you hit the spray because you are
moving.
It could get scary at times if you cant see.
I also find it does'nt take much of a puddle to pull the steering if one
wheel usually the inner one goes into it.

I am sure you are careful about where you "bow wave" goes, but if you mean
the spray that occurs at even quite low speeds I think a lot of it is thrown
up by the fatter tyres used on the newer 4x4's, skinny tires like the 205 of
the old Land Rovers and 7.50R16 that old Toyota's used seem to throw less
up.
The effect of being lifted - perhaps your higher and so hitting the water
sprayed up instead of it passing over the roof?

Hi Benoit,
If I go through long lengths of deep water I get the usual bow wave and that is
fine.
Going through water 6+ iinches deep the water sprays out foorwards and sideways
from the front tyres, which is fine.
But, going through water 2-6inches deep I seem to get a wall of spray thrown up
into the air that usually ends up on the windscreen so I can't see where I am
going unless the wipers are on full speed.
We have one or two puddles here in Gloucestershire at the moment and so I am
seeing this effect on a daily basis ;-)
Fortunately I live on a hill at the momment!

Something to do the approach angle and the wheel arch.
I can see a couple of cars from here and about 60% of the wheel
circumference is covered by the wheek arch and mud flap. The
bonnett/undercarriage is also jutting out a fair bit. I rekon this is
why cars don't have the water splash problem.
Cruisers (and other 4x4's) have to have a high approach angle - so less
wheel arch protection forward and the bonnett/undercarriage seems
shorter than on cars.
There might be a formula out there to calculate this.....
Cheers
Niall

Hi al,
While doing a splash, it's a good idea to close the air vents or else
you may get a good deal of water inside the cabin coming through the
ventilation ducts when the bow wave goes over the bonnet. Been there,
done that ...

Ok Julien now I "get it" from your reponse. I know this guy who sells Rain-X
product in France, he is millionare now! Try it on your windscreen to keep
water up into little balls so you can still see around them with easily.

Hi Benoit,
I'm a great fan of Rain-X, particularly on the side windows by the wing
mirrors, however the problem with using it on the windscreen is that it
soon degrades as the wipers still have to be used to remove some muck
and bugs.
The problem puddle bashing is the sheer volume of water that gets
thrown up onto the windscreen when you first enter the water - once in
the water it isn's such a problem because the water just sprays out the
sides.
