Increase figures are already known at 55bhp and 110 nM for both the TDV6 and the TDV8, the TDV8 is capable of more but performs best at that rating.

Thanks for all the help guys, sorry i did not reply sooner ! been away for acouple of days

The only comment would be the transfer box is probably the weakest point at the min, and by adding 110NM to the Torque figure, its then got to take 750NM when the upgrade is done.

I would just get it done though because like Rob says they are awsome when done.

Good luck with it
Let us know the outcome

No Sorry not guilty

Well I work on the Elcetronics side in the aftermarket sector. Next door we have on projects for compamies like Ford, GM, Vauxhall, Vansco, Daimler Chrysler, etc on ECU re-manufacture, dashboard panels, excavator electronics CD players, most on board vehicle electronics etc.
But sometimes I have to get involved in both mechanical and electronics because if there is a design fault we need to iron out, I have to help determine where it is. and how to get around it.
I derive from master technician status originally so I look at all aspects.
All the drive train stuff and electronics are tested in house on our own test equipment that is built and designed here. If we hit a problem that is real strange I borrow a car. If we can't borrow one and it is a large contract we buy one.
I can't say too much on here because obviously we have to sign confidentiallity agreements with most clients.

What I would say is looking at the drawings and technical spec of the transfer box at 750nM of torque, after the upgrade, it is very close to the limit. If it goes bang and the dealer find its up-graded who will foot the bill and lose the warranty.
Some dealers are OK with the up-grade. My advice would be tread very carefully with the dealers that do not recommend the upgrade.  You don't stop playing because you get old, You get old because you stop playing.

Thanks very much for the above clarification Nigel.

So it would appear NOT to be over the limit at 750 Nm (but close).

Therefore, in theory, if it went bang during the warranty period, the dealer could not attribute the cause to the chip upgrade.

So it would appear to be pretty important for the supplier of the chip upgrade to have published torque figures available for the relevant engine chip upgrade - and which have been carried out on a calibrated dyno.  Gone - 2008 TDV8, Stornoway Grey, ebony, zabrano trim, TV, Tasmods, mudflaps.

Yes but I am sure that in a court of law the warranty would only refer to a standard vehicle, NOT an up-graded one.
You must remember that it is YOUR choice to take the up-grade.

Hi Rob
Yes we get all sorts of final data from all manufaturers, such as ZF, Aisin Warner, and many vehicle manufacturers etc but as I said earlier due to strict confidential rules we can't re-produce it or pass it on in any way. Sorry
I have no problem with your product, I beleive it is an excallent software programme.
We did a lot of up-grades in the early days, that were produced here on our rolling road, when we had time, but we have now sold our rolling road and gone away from that market because of other commitments.
I am merely pointing out an opinion as a technical engineer.
It was not meant to offend. You don't stop playing because you get old, You get old because you stop playing.

So it would appear that Superchips published dyno figure of 798Nm of torque for the TDV8 might be pushing things a little too far. It might also mean a lot of black smoke and soot from the exhaust as well!

Regarding warranties, it seems generally accepted that LR would not refuse a claim unless they could attribute the defect to have been caused by the change from standard. Superchips (I have no connection with any of the chip tuning companies - just interested as an engineer and potential future customer) appear to offer a separate inclusive warranty against this - don't know if anyone has ever tested it?

I like these technical discussions.  Gone - 2008 TDV8, Stornoway Grey, ebony, zabrano trim, TV, Tasmods, mudflaps.

I've no idea what the torque capacity of the transfer box is but surely it must be able to cope with the engine torque multiplied by the ratio in low range 1st??? Consequently there is probbaly lots of torque capacity spare whilst in high range? Earlier electronic LR's remap the throttle response in low range, partially to give better controllability but maybe also to reduce the max torque available - on an auto very easy to have different max engine torque depending on which gear is engaged....

Certainly I can see the transfer box having the highest absolute torque figure applied as it is after the gearbox (where it multiplies up) and before the axles (where it has been divided down), but that does stop torque capacities being exceed firther down the drivetrain, that is after all what happens when halfshafts snap.

In the same way aircraft designers can design lighter airframes for combat (which hence give better performance) and rely upon electronics to ensure the airframe is never overloaded to failure point, I can see car designers increasingly relying upon torque sensors and electronics to protect the drivetrain by de-torquing the engine output at critical points (my D2 auto does this every gear shift!). Cheers
