    Thanks Brian

    The numbers have been added into my spreadsheet, so won't lose them again!

    The ratios are very close to the original Series box, so you could be right about going with the 1.003:1 transfer ratio (and in fact no lower than the 1.222:1).

    Cheers

    Yes, that was my S2B, in ripper condition. It had only done 50,000 miles from new, and drove like it. It wasn't RAAF,

    The main aim of the F/C camper project is for doing long trips for S1 events. The SA, Blinman event and the LROCV Horsham Gathering etc. Having done these sort of trips a number of times, it is awful getting really tired after work on Friday night and trying to have a decent nap at the side of the road in the front seat of the Range Rover. With a camper body, you can pull over, make a cuppa and a snooze in a bed.

    The vehicle needs to be able to pull itself and an 80" LR on a trailer, hence the V8 rather than a 4 cyl diesel option. (Couldn't face myself if I went to a LR event in a Toy@#% powered S2B ).

    Also being able to do the Canning would be nice - plans so far are for a D150 and a D100 APA LPG tanks which would give me 263 Lt/LPG but I would still be about 130 lt short of being able to do the canning on LPG - this is the reason for dual fuel using the standard rear petrol tank or possibly a special long range petrol tank. If I could have a rear tank of say 120 ltrs I could possibly get away with a couple of gerry cans or even the fuel drop off at Well 23.

    Ken West gave me the impression that your S2B (in the pics) was from the RAF - UK, or is that someone else's vehicle?

    Can't wait till Westy finishes his 6 X 6 FC project!

    35" muddies and 4.11:1 diffs.

    Just so that I can sort this out - when people fit 35" muddies and 4.11:1 diffs.

    What transfer box ratio do they use?

    This will help my planning.

    Quite right too. It is like a heart transplant from an unsuitable donor - the Land Rover would reject the toyota engine.

    Have you considered a 300tdi or TD5 with diesel gas? This would halve the total amount of fuel you needed to carry c/w the V8, and need only 20% of that to be gas. Power could be getting close to that of the V8 with gas and a bit more tuning.

    Campers are great - as you say, cups of tea and naps/good sleeps are laid on.

    Cheers,

    Paul

    Hey Diana

    I have fuel injected Jag V12 with strong auto that might fit lying around my back yard - do you think it would fit?

    Standard Tx ratios are used, as the diff ratio's correct the overall gearing to near enough to stock, I can't say "which" ratio as it will depend on factory fitment

    Just remember my 101 has a history of different gear ratios.
    4.7 diffs and 900x 16 tyres didnt work.
    It may work on a normal randie or Landy.....but not a FC as the aero dynamic drag is too much at speed and the small v8 are not enough.
    I am using my overdrive a lot now with the early rangie 4 speed running gear and my overdrive is running at roughly ratios etc you are chasing.
    Go to a 4.6 V8 or lower ratios.
    The Tdi 300 has not had a good record over seas in a 101 for the constant torque required gives the motor a hard time.
    Bigger displacement motors either petrol or diesel will do what you want.
    Take note a early ragie transfer case can be fitted with a pto below the normal Pto plate at the back of the transfer case....I dont know the details.
    Reread the my 101 details ,members vehicles.
    Catch up with me at Nowra and drive my 101 and you will see where I coming from.

    The frontal surface area (wind resistance) and the 9.00 tyres are what have concerned me for a while. This is why the Defender 1.41:1 high transfer ratio was somewhat attractive as it is the closest to the original 1.53:1 of the F/C gearbox. The overdrive 5th will be very similar to the fairy overdrive ratio, so the comparison with your 101 would be good.

    Can you confirm something for me - I have the LT95 in the 101 listed as a 1.174:1 for the high transfer ratio is that correct?

    If the 1.174 is correct and using the 5.57 diffs your final drive is 6.539:1 while an LT230 with the defender 1.41 ratio over 4.7 diffs would be 6.627:1 and the similarly the Disco ratio 1.222 would end up at 5.743:1, both quite acceptable comparisons although the 1.41 the closest.

    My plan is for the 3.9 engine to start and then possibly change to a 4.6 if/when the engine needs reconditioning. I think that the engineering approval will be easier with the 3.9 to start.

    Whether I close the 1.222 or the 1.41 will depend on availability, and if I select wrong I believe that the change over is a simple swap over of the gear sets.
