Should i swap it over?

YES!
If you think it's bad on the V8 then wait till the TDi sees the tyres!! :shock:
I've got a large intercooler, uprated injector pump, EGR & cat have gone, K&N airfilter & Safari Snorkel fitted and 33" tyres, with the 1.22 T-box it still turned it's nose up when it saw a hill from 2 miles away.
The 1.410 T-box brought it back to normal and I could pull away in second, accelorate up hill and do 30 in 4th & 40 in 5th. Sure, the revs are up a bit and the consumption is a bit heavier than before but it's so much better to drive. :wink:
Jake:
Cheers Budgie.
Looks like i'm swapping the transfer box then!
:roll:
landyman Ash:
Okay so this is new to me, I was always under the impression the boxes had the same ratio but then again Ive run V8's forever!!
Now Ive got a Tdi I do have the option to change as I've LOADS of V8 transfer boxes kicking around.
Im running a 300tdi auto so are the transfer boxes on that different? Will the V8 transfer box off the auto make it better?
I have to say towing the hybrid is SLOW!!!! :x :x
Budgie:
The normal Disco & Rangie transfer box is a 1.22:1 ratio box. The one I fitted was from a TD5 Defender which is a 1.41:1 ratio and the earlier 90/110s used 1.6:1 transfer boxes.
The 1.22 t-box was okay with the 31" tyres but then I fitted the 33" tyres and Boy did I notice the difference!
The other option to changing the T-box is to change the Ring & Pinion in both diffs to the 4.11 from the standard 3.54 ratio. See Ashcrofts site for details.
