Towing 1 Ton- V8 or TD5

[vogue]

Is there much difference between the two when towing a 1 ton camper trailer? Will they both hold good speed on the hills? I'm sick of going slow up hills (currently have a '97 2.7 Prado).

chipped the td5 will pull about 1.5 T up the toowomba range with ease so much ease that you will be cursing the cars in the right hand lane.

Chipped Td5 will outperform a V8, and use half the fuel doing it.

Forget the petrol engines, innefficient things of the past.....:p

as a usefull guide DAVE,,,
towed the camper up the range after the DO (last weekend)
2nd gear at 60 kph,,,

funnily enough DAVE,,, thats the current speed limit UP the range,,(you camo guys must have special licences:p)
so even if you had a D4 (my next car, yes Justin,, it will be a diesel) with 600 odd twists,, you are still limited as to how fast you can travel.

There's no need, search and you will find the answer to your question



a 200Tdi would just about be the perfect commuter,,

No special liscence, just my hatred of sphincter nibblers who, when you've just popped into the right lane to go past a semi decide to go racing up the left lane, cut you off and then go at a speed thats just under the limit and right on the change point between 2 gears.

then at the top they have the audacity to apologise and say "sorry, I had no idea that you 'd be able to do the speed limit up the hill"

and the last time I went up the limit was 70 most of the way except for where you crest out into the roundabout where its 60.

My D2 Manual 4.0 V8 tows my 21 foot vagabond (2 tonn) very nicely. I was in second to third up the Cunningham's gap range (with a VERY loaded vehicle and boat with camping gear) always backing off for my brother in law's Isuzu TD Holden Rodeo who was towing an old ski boat at a fair bit under my weight....ohh...I was running on LPG too.

When you are talking a tonn you wont notice if behind the V8. The TD5 chipped, who knows...some people reckon they are better than the bent 8 but has anyone taken them out and dragged them side by side with a load...perhaps the TD5's impressive clunks and pings under the bonnet and the symphony of 5 cylinder noise makes it all seem so fast:wasntme:

The V8 sounds like a large burbling sowing machine its so smooth when revving out....nice. Run it on LPG and forget about it.

Cheers

Do you have a white van/boat....:wasntme:

Picture what you have, and then add 60% more peak torque which is all in a rev range where you use it all and with better fuel consumption.

Thats a chipped/intercooled TD5. :cool:

[ozscott]

I was just having some fun. The chipped TD5 must be good because the original without mods was a bit light on, so many people are modding their TD5's and their figures are clearly good on the dyno. They seem to be lasting dont they? That was my concern with upping the HP so much, but Slunnie has addressed this before - it all seems impressive really.

Cheers

PS...now if I could just get past the knocking sound...

[Slunnie]

Yeah, you can up the power, but the tranny might not like it. :(

[ozscott]

Simon - you talking manual, auto or both?

Cheers

[ozscott]

save for the larger longer lasting clutch on the V8's I get the impression that the stock TD5/V8 is a truck that is all in balance...up the power too much and you risk injury to the drivetrain somewhere - diff, axles, tranny etc.

My understanding is that the Td5's were dumbed down to meet the Australian emission standards. So, all things being equal and as long as you don't go past the original european specs .... SHOULD all be OK.

My non-chipped manual Td5 happily tows my 1 tonne camper trailer. It does slow down on hills, but I'm not trying to win any races and let's face it .... it's a large 4WD and not designed to be driven fast .... especially with a tonne or two on the back.

...... and I love the sound of the diesel.

Oh, I was really talking about the autos, but I think the manuals are the same as they drop 5th gear.

dumbed down? What has been dumbed down?

The only difference that I knew of was that the Aus spec vehicles came with hot climate specs (ie bigger radiators etc). Thats at least what I thought.

[Traco]

For towing you want torque. The 4.0 V8 doesn't really produce enough of it in a heavy 4x4. Ideally the long stroke 4.6 with a high torque cam is what's needed - this will have 300+ ftlb of stump pulling power, enough to make your nose bleed.

A chipped TD5 may be able to hold its own with the 4.0 but a worked 4.6 will leave it standing. And then there's the noise it will make ..... and it won't be clatter, clatter.

For the money you save on buying a V8 over the TD you could probably put a 4.6 in it. Fuel consumption will be worse than the TD of course, but maybe a bit better than the 4.0. On the other hand the V8 will be relatively cheap and easy to service compared to the diesel, so you'll save money there.

You are probably right!
What I meant was the TD5 was designed to have a far greater output than it's current specs, but had to meet the Euro III emisions standard.
So it's capable of an upgrade without to many other mods to cope .... however after an ECU upgrade may not comply with Australia's current emmision laws ...... and now we're getting off topic. ;)

..I just love my supercharged 3.9, 4500 revs and 9psi boost towing 2tonnes of metal float and horse flesh just under the legal limt on the steepest of Tassie hills...

The exhaust note sounds wonderful only tempered by the intermittant roar of the viscous fan cutting in and out, in and out...until the next servo that is, when all is quiet again:o

PS, as a comparison a D3 owner I know completed 800 plus klms trip towing a double horse float with 2 large (15,17h) nags on board averaging 12L/100klm (normally 8-9L/100klms), with speeds of up to 110kph!! Far too fast - but twas not me driving. Downside, service and repair costs - brake probs from repeatedly stopping that weight (far too little trailer assist), and an air suspenison sensor failure to boot - the Stealer had a field day:twisted:

[vogue]

What are the torque figures of a V8, a standard TD5 and a chiped TD5?
And at what revs?
I'm not used to diesels, so approx how many revs would you do up medium hills?

[ozscott]

Now your talking - either supercharged low compression 3.9/4.0 or a 4.6 with some anger and its a whole different ballgame (and again for the naturally aspirated one on LPG very cost effective)...now if I could only kill my bloody V8s...285k on the 3.9 and 155k on the 4.0!!!!

From memory the D2 td5 has 310nm, the D2a Td5 has 340nm, the V8 from memory is up there as well. I have the D2a td5 stock standard a family of 6 and tow a 900kg camper. Cruising at 100k the torque converter is locked and it sits on 2300 revs it will hold the speed on most hills. Having had the D1 3.9 litre V8 and now the td5 they both do the job in different ways. On a short country run with city driving as well towing the campervan i use 12.5L/100km. The SLS is awesome load the D2 up and she just levels herself out. NO wandering all over the place like my mates Prado when it is loaded up. .

Nankas

P.S. The only thing i miss about the V8 is that sound, sighhhhhhhh

[rovercare]

Diesel for towing, don;t see many petrol trucks around these days do we:D

[Slunnie]

Chip and I/C are anything from standard up to about 165kw/530Nm.
