Thread: fuel consumption desert P38 V8

I can't help with consumption figures but can tell you that long range tanks were made for the P38A by a company in Australia - Brown Davis. I had a 150 litre tank in mine. There are two variations, one for GEMS and one for the later Bosch Motronic cars.

This is the one I had in my GEMS.

Thanks!

That does look the business but is it just me or does the fuel tank hang quite low? If so that would pose a serious clearing problem, potentially.

I am currently thinking about converting my spare wheel well to a fuel tank. Of course I would insert a tank inside it, not convert the wheel well itself I reckon I could easily fit 90 litres in there. Most LPG conversion store a 90L donut shaped tank there I heard so if I make a square tank to fill the entire well I should have plenty of extra fuel. I'd close it of on top for safety and have baffle plates inside the tank etc. but I think that would be my best bet. I had hoped to use that space for water but that'll have to go someplace else then.

Now just to get some fuel consumption figures and I'm golden

desert driving is usualy +20% of what your blacktop consumption

thanks

I currently do ~ 14.8L/100KM unless I get caught in a (long) traffic jam or do city driving only so that would mean that'd go up to 17.8 roughly.

Taking the 1000km between fueling as a baseline, I would end up with 178 litres. I guess that spare wheel well I idea might work out!

Just finished Fraser Island trip with full load and trailer. Averaged 20L/100km in mostly firm sand.

I would think that you should plan on about 20-25L per 100Kms.

It depends of course on your driving style ,how dry it is so how soft the sand, how chopped up the dunes are, and what detours you would have to take if it's wet.

This is why diesels are popular for this type of thing, as they use comparatively less fuel in low accelerator position work as well as less fuel overall.

During a weekend Navrun in our Little Desert here I was averaging around the 23-25L/100 with stock size tyres and fairly 'spirited' driving.

Would desperately love a long range tank. One day.

It's been a couple of years, I know Anyway, since the build plans on the range rover are beginning to shape up for next years trip I revisited the whole "extra fuel" chapter and I came across this in my notes. I see the long range tanks are still available on the site of brown davis so it should be possible to obtain one. What I am currently looking into is the weight of several options, that being the most important factor of course. When I look up close it strikes that the tank is made of composite? Or is it made out of steel? Would you happen to remember what it weighed?

Thanks!
