Just received a Nov build date for the new V8.

Changed my order from the V6 to the V8 with only an extra month to wait

I take it we are talking about the diesel.

Why do LandRover always end up looking second best? Landrover bring out a 130 2.5 5 cylinder engine, and Nissan put a 150bhp 4 pot in their Navara.

Same as the TDV8, it is well undersquare with only 3.6 litres. Why the hell is it not 4.0, like all good V8s should be?

It might sound good, but it is still weedy in comparison to the Toureg V10, 5.0.

Why do LandRover always bring out inferior engines, 5 years after their rivals?

you have a point there with the exception of the 4.2 Supercharged they do lack a bit in the power department, also i thought the new V8 diesel was only for the big Rangie and the sport got the V6?

I saw the TDV8 at the motorshow and the facelift looks to be interior based with revisions to dash and centre console around gearlever with similar design to D3 and terrain response. Also some new seats and trim combo's, including new paint colours.

Do you mean the Range Rover Sport? - If so how much extra dod you have to pay for the V8 diesel engine rather than the V6?

It's the V8 Diesel in the RR Sport.

Cost over and above the V6 works out at around an extra £4,000 but I get my cars tax free with a discount so not sure about the normal UK price.

the engine may seem a weedy 3.6 litre but they produce fenominal amounts of torque (600+nm iirc) having looked thouroughly around the new tdv8 at the landrover technicial academy i dont fancy doing a nearside turbo in situe much

Indeed it does produce lots of torque, so much that it is limited to 640Nm at 1750-2500 rpm so it doesn't break the ZF 6HP26 auto-transmission. It also produces 530Nm at 1500rpm. Also the there is a little known benefit of having maximum torque and a slow rising power afterwards (ultimately at the expense of outright max power not that 200kW is weedy). Called 'torque-rise' it increases the ability of an engine to 'lug' longer in the same gear (riding up the torque curve as rpm drops) at a given hill ascent or tow before changing down. Truck and tractor drivers know about this, and this is probably quite useful on a 4x4. The other benefit is that you can spec a smaller turbo and therefore reduce the turbo spool-up time.

So if it can do all this with 3.6 litres, why does it need any more?

BTW Mr bluespanner don't even think about comparing this engine to that enormous rattling ing oil refinery underneath the toerag bonnet.

Are you saying that 308 bhp and 750nm of tourque is not better?

I take it you didn't understand my post about transmission torque capacity and the phenomenon of 'torque rise' for the benefit of towing and hill ascent on 4x4 vehicles. Perhaps you need an engineering degree to understand this?

In answer to your 'top trumps' question (I guess you are talking about the VW V10) then when the price is the installation of an enormous, hugely heavy, less fuel-efficient and noisier truck engine that compromises the rest of the vehicle to hell then yes I am.

But if it bothers you that much there is plenty of scope in the TDV8 cylinder block to increase capacity and more than enough strength to increase power and torque when required. I should know I designed it!

All the best

OK i get the idea.

Hats off to you mate if you designed it!

What do you reckon its tuneable to?

Can't say I designed it totally (that would be impossible!) several dozen people worked on it, but I played my part on the block and a few bits around it!

As for what it's tunable to I'm not in calibration so I don't know fully, however the turbo's will be matched for it's 4x4 application requiring fast spool-up and so they are relatively small. This means that there will be an airflow limitations at the topend revs reducing scope for large power hikes. Also I'm guessing that injector flow rate capability will also be matched for designed power range (for controlability) limiting the amount of fuel at the topend aswell. However it would not surprise me if Superchips (or suchlike) break 700Nm and get close to 300bhp, not that I would recommend that though.
