High Range Gearing
Mace:
BTM I have the opposite problem with my Disco being overgeared now I've got 32" tyres on. I'd like to do as Budgie has said and do a straight swap, my Disco transfer box for a defender transfer box, this will sort me out and give me scope for upping the tyre size in the future. Not got round to it yet as I'd have to do the exchange with ashcrofts and pay for the privilege.
However, I've a friend with 8.25's on his 90. He find's it cruises very well at 70 mph and it will pull the caravan without much trouble. He's not got a full blown intercooler upgrade either so he's not got as much power as your td5 should have. He says it's certainly quieter and more relaxing (once you get going).
I've got a spreadsheet somewhere that tells me what Transfer Box ratios - tyre sizes give what speeds. If you've got a particular speed / rpm in mind then I can work out what ratio / tyre size combination is best.

I forgot that place existed, not been in there for over 18 months!!
So you're still torn between the overdrive & the transfer box then Richard? How do these compare with getting the TD5 re-chipped? That increase in engine power maybe all that's needed. :-k
I suppose it's what's going to give the best benefits for the money really!! :wink:

Not so interested in more power, higher-gearing (less revs for same speed) is the issue for me

Overdrive gives you the option for higher gears on motorways and flat roads, yet leaves you lower gearing when required for hilly climates or heavy loads.
