Thread: A couple Fender TD5 questions

You could also look at putting in some Disco transfer gears instead of the overdrive.

Do a search for Ashcrofts in the UK as I remember they had some info on doing this.

There are also a few previous postings on this topic, so you could try searching here too.

Ratio Upgrade £225 If your TD5 90/110 or Tdi revs excessively on the motorway we are able to raise your transfer case gearing by 15%, by replacing the gearing in the exising 1.410 ratio transfer box with new 1.222 gears, as used in the Disco. This will not only reduce your revs but also reduce noise. This change will not effect Low Range and will leave your Speedo reading true. .
Gear Set only £225 new outright



From here: Ashcroft Transmissions

GKN do an overdrive which is activated by a switch on the top of the gear lever. Can't find a good link to them, but it was reviewed in an edition of Overlander magazine some years back.

Ashcroft kit works a treat, although in hindsight, it would've been cheaper find a good 2nd hand LT230 from a S2 Disco, selling the Def Tcase and fitting that...

Increased the fuel economy about 0.5-1L/100 too

As for the gas td5, I think someone tried it a while back, only to have the engine destroy itself about 200kms later... Don't think anyone has been game to try it since...

why would you gas it? i thought it gave power not economy? as you cant run pure gas it has to be mixed? (im probably wrong tho arent i? ) some of the guys have been running 180kw + through the td5 with a few tweaks... intercooler... ecu reprogram.. etc etc etc oh and a gearbox every 20000k's

Thanks

Exactly why I'm still a tad nervous at the idea of re-chiping

if you get it done (mines at 140kw) mildly then there are no issues just better drive, better towing, and better economy, but running it at 180kw+ and monster torque figures then you expect something to give.. especially in a driveline that isnt designed for that much power! as has been stated on here many a time, the mild tune is how it should have been sold!

thanks

The System runs at approx 20% gas 80% diesel.
I would be doing the mod because the State and Federal Govs pay for most of the conversion costs, its like adding a long range tank and gas is cheaper so will lower the running costs a little.
I wasn't after a power increase though the Fender will be tested next week when I tow a loaded camper trailer ( approx 1900 kg) so I may want a power tweek in the future.
