[Fuel consumption] for mike

Guten Morgen Mike
Had yesterday off - I spent all weekend at a motor rally. This is my
first day back at work for a few days. So I haven't been able to get
back to you.
Re fuel consumption; at what speeds are you interested in the fuel
consumption? and on what terrain - hamada or sand?
Fuel consumption rises to quite high on soft sand - typically, in mpg
figures (about 9-15 mpgallon (that is, 3.5 miles per km) at about 40-42
mph). It all depends on the softness and what time of day it is - in the
night I can get more because the sand becomes a little more
consolidated. When the sand is really soft then it drops to the above
figures. On some occasions, quite rarely it drops to about 5 miles per
gallon. But this is only in extreme cases.
Hamadas are different (that is, gravel, and chert/flint lake bed
deposits). I get
about 23-26 mpgallon at about 45 mph. In the UK I usually get about 26
mpgallon at 55 mph. Hamadas are dangerous stuff and can't be taken very
fast because it can shred tyres as if its going out of fashion. In 2001
we had three vehicles and lost all 12 of out brand new Michelin all
terrain tyres within 24 hours that year on the sharp stuff.
I'm considering boosting up the fuel economy by fitting an intercooler
or something similar, as I want to get at least 35 to a gallon. Its not
really a problem with me as I have 400 ltrs of fuel to play with when I
fill up. But it would be nice to get a bit more.

Mike,
As a matter of fact I have no specific figures yet. All I can offer
at the moment is a rule of thumb - offroad with full load expect
figures 20 - 25% higher than city cycle. On soft ground and dunes,
even 100% higher..

Hi Renate,
Welcome back. Which rally did you go to see?
You will never get close to 35mpg from your 80, the best you could
expect is around the 28mpg mark with an intercooler, large bore exhaust,
serviced injectors, pump, etc. You are doing pretty well to get around
26mpg.
You could get up to around 35mpg like Dermot if you have a manual
24valve (1HD-FT) with an intercooler and large bore exhaust, but not
with a 12valve.
Having said that a propane injection system will help improve the
consumption further, but fill up points in the desert will be few and
far between!

I should think Natural Gas injection would help a bit.
One could ferment camel dung, collect the methane and add it to the air intake at low pressure. The plumbing might be a bit awkward, but maybe this explains why I saw so many camels in the back of (Toyota) pickup trucks during my time in the Middle East?
Supplementary question: how one earth does one get a camel to climb into a pickup truck in the first place?

Yes, gas propellent....nitro might do...wacky races and scrapheal
challenege all rolled into one...
Yes, actually, camel dung - good for fire, maybe fermenting them in
those great tunisian granaries might be good?

Of course, you are pulling my leg, arn't you, ol' man?!

You don't, you stick a couple of sand ladders, or failing this, some
planks of wood into the back of the pickup and the ground, and spend the
rest of the next 24 hours co-ercing complaining camels into the back,
and you yank them in by tying that blue nylon rope around head harness
and pulling and shoving them in until they all get there....you eff and
blind until you''re blue in the face, and sweat is pouring down you just
like a wadi in full flood, and if this fails you beat them until they
submit....
The usual way of dealing with things...
Hope this helps...

Hallo, liebe Renate
Thank u for the mail. I think i shall be doing at this planned journey
more sand and mud.(Lybia/Niger- cameroun/RSA). How did u get to 400 litres?
How many tanks have u got?
When I am back i would like to look at yours and romans car. that ought to
be middle/end june. up to than i ll be in sunny south africa. will try and
fit some diving into my trip but will sadly have to do some work as well.
Your fuel consumptions are very good. Gives me something to calculate on.
On my Magirus i had 1200 lit. diesel - that makes travelling so cheap and
gives me a range of almost 5000 km. But i wanted to downsize so i`ll be happy
260 l.
You not the only one with tyre problems and michelins: I had 18!!!! punctures
and 3 complete losses (michelin XS 14.5x20) I will never support that company
again in my life!!
Hope to get to meet the Africa people
when back
regards
mike

I will look forward to seeing you when you get back.
The Africa crowd I think, should meet on a regular basis.
I'm thinking of getting a web page up and running soon, I'll let you
all know in good time.
Whilst in South Africa you will automatically gain experience
off-roading. Take it easy, relax and enjoy the experience. You will
probably find you learn a lot of things easily as you are already doing
it on a day to day basis. If your work is a hectic schedule, at least
try and fit in a few hours off-roading on a regular basis if you are
able.
I was last in south Africa in 1996, I was working in the Museums
Service out there, the base was the Museum of Man as was, in Jo'burg. I
was based in Kimberley, North Cape Province. My first trip to Africa
was the year before and I learnt some very valuable lessons that year,
lessons that I have never forgotten, and not likely to. Ever since
Africa is the place for me to be. I miss it terribly when I'm not
there. Here in the UK I'm incredibly frustrated 'cos my bad salary
ensures that 'The Corporation' runs my life, every second, every day of
every week - they control whether I eat and what I eat, how much fuel
for l'beast, control how I get to work, control my socialising, and
worst of all, l'beast and travelling. I was talking to a work colleague
today and explained how I felt about everything, in my very peculiar way
of using metaphors and other such things. He said he hadn't thought of
it like this way before, and he certainly would now. My salary is
abysmal. Rent takes 2 thirds of this which leaves nothing much for
electric, gas, council tax, water rates, food, cat food, diesel. I've
come to the conclusion that it is time to get out of here and find a job
more conducive to my travels. A close friend of mine is having the same
problem so we've decided to pool our salaries together because by doing
this we can both pay for bikes and beast bits, eat, buy fuel, and
socialise, although not that much. Basicly its a survival strategy
Your trip is making me want to run out of this place right now! I will
think of you many times when you've gone, and so when you get back we
must meet.

Renate
