3.6L TDV8

[Graeme]

Is the 3.6L TDV8 fitted to 2007+ RRS the same specification 3.6L engine as fitted to the Vogue of the same era - ie twin variable geometry turbos, same HP & torque?
TIA

[CSBrisie]

Yes, identical.

Wanted one until I saw the TDV6 was 180Kw and 600NM (versus 200Kw and 640nm).

Now I want a 4.4TDV8 - damn LR for the constant improvements!!!! :D

[BigJon]

Ask Sniegy if you really want a 4.4 TDV8. I am very happy so far with the 3.6. Perhaps a little thirsty around town, but that grunt, that noise, who cares? :D:burnrubber:

[CSBrisie]

hmmmm.....cryptic....issues with the 4.4?? I just want the combo of 8 speed and 700plus NM ;)

[BigJon]

Apparently.

640nm is pretty good. 6 speeds appear to be adequate.

[discojools]

3.6 TDV8 is the same in the Sport and the Vogue...What a lovely engine!! I miss my Sport..
Mmm maybe get a new Sport available next June with 4.4! Can dream.

Should be a real goer with 400kg less weight and I think more power than current 4.4 TDV8

[Graeme]

A brother likes the 3.6 Vogue but their cost for their age is a little high for him. Therefore he's considering a later 3.6 TDV8 RRS if it has the same engine configuration or a 3.0 D4 to tow his medium-sized van. His '86 RRC with a big Chev donk struggles too much for his liking and also he doesn't want to risk it breaking down away from home, being a mix of parts both from other vehicles and home-made.

its such a shame that the tdv8 wasnt available in the discovery

its like a silly brand protection thing. lots of manufacturers do it. BMW are the worst at it. abit off topic but imagine the car the m3 would have been with that v10, and simarly the new one with the TTv8. Its like they detune the less expensive model it to be 1 1/10 slower over the 0-100 sprint,
Nevermind rant over.

It is seriously bad form to have the cheap vehicles out sprinting the expensive ones.
But you can always build one yourself if you want it that much.

[d3viate]

Bit off topic maybe but interested if anybody has ever heard of the V8 Diesel fitting in the D3 engine bay ?
Like mentioned here, would love to hear that engine note, its a beautiful thing and would create a rip roaring off roader and muuuuch better overtaking.
I assumed the chassis is the same but maybe somebody can put me out of my misery why it cannot happen. Thanks.

[CSBrisie]

Would be interesting to hear ( a comparison) from anyone who had a TDV8 RRS and now owns a new 3.0LTDV6 RRS....??

[Graeme]

IIRC the 3.0 out-performs the 3.6 TDV8.

[CaverD3]

You can get the 3.0L remapped to 697Nm. :D:BigThumb:

LR have put it in their poverty spec FFRR but not sure what figures they are quoting for it.

[BigJon]

I think I have read that the 3.6 can be remapped to over 800Nm...

[CaverD3]

831Nm to be exact.

http://www.mybluefin.com.au/search'make=17&fueltype=2&model=75&variant=1714

I have heard that at this much likelihood of failure increases.

[harlie]

I can confirm that it is really nice:D.

Back to Back compare with a stock 5.0 V10Tdi Toureg, the remapped 3.6 L322 feels sharper, possibly because it is opperating at higher rpm. The V10 trans shift mapping keeps it's running at 1050-1100rpm.

[camel_landy]

I drive all of them... All of the time. :D

The 3.0 SDV6 is nice but there is just something about the sound & power delivery of the TDV8 that the SDV6 just lacks. ;)

I find the change-over from 1 to 2 turbos provides non-linear power delivery that's probably a lot smoother with the TDV8's 2 turbos operating all the time combined with the larger capacity engine.

I haven't driven the rover TDV8, but I wouldn't expect their turbos to run the whole time. Single stage VNT's can only work over a certain rpm range. But the larger displacement will help with torque before you're into full boost.

[discojools]

The 3.6 TDV8 has twin turbos but not sequential. The 4.4 TDV8 in the FFR has twin sequential turbos... There was always a little pause with the power delivery of my TDV8Sport, something you got used to eventually a bit like the 2.7 TDV6.
Just a side note, something I just read: The new Supercharged Sport is now the fastest SUV round Nurembourg and also the fastest SUV up Pikes Peak! Something for Porsche to think about...

I guess the battle to save our language from the American SUV terminology has been well and truly lost. :(

[Graeme]

I wouldn't expect their turbos to run the whole time.Please explain! The 3.0 produces 500nm within half a second of take-off using its single VVT primary turbo (TDV8 with 2 VVT) so I'd expect the 3.6 to be in the same league.

[gghaggis]

The TDV8 3.6 has greater lag from takeoff (hence why the 3.0 is only around 0.1sec slower to 100kph, and is faster to 60kph) - but greater mid-range acceleration.

Cheers,

Gordon

I have commented in the past that in a drag race between my 3.9 Classic and my 3.6 Vogue the Classic would win for the first second or two, then the Vogue would just walk away.

The 3.0 has two sequential turbos.
A very small one to start spinning up very early and a larger one to take over.

The 3.6 has two equal turbos. It is essentially 2x 1.8L turbocharged 4 cyl's sharing a crank. One turbo has to cover the range of engine rpm and boost, so compromises exist. This compromise is in low down boost.

I would have thought your statement to be correct and logical however Wikipedia says

The 3.0-litre design, known as the Gen III, superseded the 2.7-litre, and uses parallel sequential turbochargers and an uprated commonrail injection system incorporating fuel injectors with piezo crystals fitted nearer to the tip to reduce engine noise and a metering mode to reduce oversupplying fuel, decreasing fuel consumption and unused fuel temperature over the 2.7-litre model. The parallel sequential turbocharger system utilises the larger of the two turbos when the engine is running at low revolutions; once the engine has reached 2,800 rpm, the smaller turbocharger is used to push boosted air to the larger turbo’s intake port, prior to the small turbocharger’s boosted air is redirected to the intercooler 300 milliseconds later.

The issue with Wikipedia is that anyone can put information so the information may not be reliable.

That bit ^^.
Whoever edited the wiki page has it wrong and has written a terribly confusing piece that's full of errors any makes no sense in many parts.
"unused fuel temperature"?

[Graeme]

The 3.0's primary VVT turbo is indeed the larger one doing most of the work with the fixed geometry secondary turbo only used to top-up the smaller one.

[Graeme]

One turbo has to cover the range of engine rpm and boost, so compromises exist. This compromise is in low down boost.I believe its at the top-end that the compomise is made, if any, remembering that they are VVT providing fast spool-up when needed. But regardless, the turbos are always in use excepting perhaps not as much as might be preferred just above idle so stating that the turbos would not be running all the time is way off the mark.

Yep lost...I sometimes wonder whether allot of us Aussies just wanna be yanks the way we copy their language and mannerisms.

Also don't believe anything you read on Wikipedia...I know from personal experience.

Nope.

Back to diesels

A mate has a TD 4.2 Quatro,it left the 3.0l RRS(now superseded) for dead.

As for the latest diesel RRS and RR,i think it may still pip them?

Maybe not?

But then again it is not really in the same off road league,no T/C,etc.....
