Tdi maximum revs....

[rick130]

or how mechanically deaf are you ?? :wink:

For those with a tacho in their Tdi, what are the maximum revs you've ever seen and under what conditions ?
I'm curious what a 'normal' operating range is for most and what they've seen in an 'extreme' situation.

ta.

I honestly cannot really tell you as I did not check it myself, but...
[list]-in everyday use you rarely have to go past 3.000 rpm
-in our place of the world you have those funny emission checks one a year where they rev the engine until the govenor kicks in. This has to be done three (sic!) times consecutively :x ouch! If the cambelt is fine, the engine will, well, tolerate it
-I believe (a matter of faith, eh?) the govenor is set to about 5.000rpm[list]

Happy Australia Day, mate!

[landrovermick]

I have had the 93 three door disco up to a dollar sixty on the speedo - was revving to about 4.2 grand - would never do it again ....

TDI Auto in the Discovery

60kph 1600-2000 something like that
80kph 1800rpm in fourth
100kph 2250 in fourth

really they don't want to rev seem to hit the wall at about 4000rpm

Hope that helps.

[one_iota]

Mine runs out of breath at 4,000. Then usually only used in first gear and on rare occassions.

[disconut]

According to the disc the Max governed speed is 4850 rev per min.

I have run to 4000 in 3rd a couple of times, and I have hit 150k a couple of times but did not check the revs. I suspect 4000 in 5th is 150.

Trev.

[incisor]

had mine to 4200 a few times and it is still pulling fine... much easier to get there since the teak up

[seqfisho]

Held flat with the Auto they up change at 4000rpm through every change to top, although I have never revved to 4000 in top :roll:

I know the manuals have the govenor around 4500-4750 8O 8O


Thats scary in a diesel, but they were designed to rev a little more than the bigger diesels https://www.aulro.com/afvb/

[Defender200Tdi]

Well, now I don't know if my 200tdi is a bit crook or whether the (VDO) tacho isn't reading right. My engine seems to struggle much beyond 3000rpm, at least, that's where I start feeling too sympathetic to push it much further. Beyond 3000rpm doesn't seem to achieve anything in my beast anyway, other than making more noise.

Maybe the tacho is out, but I did set it up with an optical tacho when I installed it, and I can confirm that it's spot on at 1000rpm and 2000rpm.


Paul https://www.aulro.com/afvb/

[timberwolf_302]

Yeah. Diesels like a flogging every now and again, keeps them clean. They hate putting around.

If you do alot of town driving, its good to do a highway run occasionally doing between 3500 and the governed speed for a few mins to blast the coke off the pistons.

[incisor]

working them out at higher than normal revs up a big long hill does wonders if they have been idling around.

[Tusker]

Yeah but for best performance there's no point revving it much past the peak power point.

The TD5 for example has a very lumpy power curve, it drops big time as it heads towards the 4600 rpm maximum. But theres not much oomph up there, better to change up at about 3000 rpm.

Regards
Max P

[sclarke]

mine has no tacho. Thank god as i dont want to know what it does on some climbs.
there has been times when i've hit it hard in 1st low or 2nd just to get over that hill or obstical.

i doubt its been past 4,500. but who knows...

it has seen $1.60 on the speedo.... on a down hill run

[timberwolf_302]

It is amazing what we'll do to get over some obstacles in our adventures.

On many occasions Ive been in the Rangie powering up a muddy slope, losing momentum and getting frustrated, revving it up to 6000rpm in Low 2nd...and nearly going through the windscreen when i make it to the top and let my foot off the accelerator.

Maybe I should pay attention to the Warning Placard in front of the Gear Shifter;

"Avoid wide throttle openings when used in conjunction with 1st and 2nd gear Low Range"

[one_iota]

Whilst the Tdi will slug around on and off road below 2000 rpm there is a really sweet spot just above 3000 rpm that can be used both on and off road low or high range. https://www.aulro.com/afvb/

Usually looking at the road though

Incisors 300tdi disco: 100kph==2200-2250 rpm flat highway running

After Tweek: 100kph==2000 rpm flat highway running

Smoother power curve just wants to pull https://www.aulro.com/afvb/

[rick130]

thanks fella's.
I've always liked as small a scale in a tacho as possible, and in the calcs I've done it doesn't look like I ever go over 3500. It just seems to stop pulling, even just before then, but sometimes you need to hang on to a gear a little longer (eg. 85km/h 3rd, 255/85's =3500)
Even so, I was wondering if a 0-4000 RPM tacho was slightly too low a scale, as a 0-7000 RPM scale seems a waste.
I used to use over 7000RPM ocaisonally in the race car with a 7000RPM scale and it wasn't a problem so..
What do you all think ??

[timberwolf_302]

6000 would be the easiest answer, as it is in Discoverys and Rangies with Full Instrumentation Dashes.

But Ive seen some after market Tachos that only go up to 4000, and 5000 (probably for industrial use or something).

Are you saying you want to purchase a Tacho For the Defender? I think there was a post a while back about Defender Tachos that fit in the dash replacing the clock. I think it was a 6000 scaled tacho.

Anyone remember this particular post?

[Defender200Tdi]

My VDO tacho is a 6000rpm jobbie, only because it was all that was available from them at the time. If I'd had my druthers, I'd go for a 4000rpm model.

crikey Paul,
I've only just got the interior light working working for the first time in 4 years, these things take time.... :wink:

If I throw a tacho in, it will be an 80-85mm on top of dash deal. I've already replaced the OE thermometer with a VDO mechanical one, and the clock with a 0-15 psi boost gauge and one of Ian's EGT readouts sits on top of the dash in its own little box.

[Grizzly_Adams]

oooh I'd love to see some piccies of that Rick, any chance?? 8)

I'm trying to figure out where to put all the guages I want to put in to her, haven't quite sussed it yet.

Defender200tdi what have you done with the radio?

[sheff]

From the W/S manual (LRL0079) Max. no load governed engine speed is 4600 + 40 - 120rpm. (whatever that means.)
Mine has never been driven over about 3600, but once in a lapse of concentration I dropped back from 5th. to 2nd. at about 80kph. I didnt catch the rpm, too busy climbing back off the steering wheel, left foot looking for the clutch. :oops:

<div class='quotetop'>QUOTE</div><div class='quotemain'>Defender200tdi what have you done with the radio?[/b][/quote]

The UHF is mounted on the side of the centre console. It's a GME 4400 with the front firing speaker, which works well pointing up at the driver. The radio cassette is in the garage!

Plan is for one of those roof consoles to house a new radio/mp3 player and the UHF. Like this:

l don't know if l'm a wus, but if l get to just over 3000 rpm l feel like getting the fishing net out to catch the pistons, seriously, and being an ex mechanic, l find it hard to go over the 3k mark ( 300 series disco manual hi flow filter 3" exhaust and 270,000 km )

[Slunnie]

Geez, 3K! Mind you there isn't much to be had over 3K I'd reckon. Works LC100DX give nothing extra over 3K, but the Disco (TD5) will pull to about 4200rpm when it changes, and I think the limiter is at 4750rpm or something.

I agree fridge1, my 170,000km 200tdi with upped boost & fueling feels exactly the same. You'd have to have no mechanical sympathy to push it past 3000rpm.

Paul https://www.aulro.com/afvb/

[sjd70]

I had my Disco at 4200rpm in 2nd gear low range to get around Indian Head at Fraser Is recently. That said I was a little busy looking where I was going so I may have done more.

Boy was that bypass a mess from all the hoilday traffic!

cheers

[Slunnie]

Yeah, there were a lot of 4WD's down to their bellys there when I was there around New Years. Some just couldn't get through at all.

Hey Paul ( 200 tdi ) where did you get the up fueling and turbo adjustment done and did you notice the up grade on the defender Mark

[rick130]

IIRC, he did it himself.
He's pretty handy with the tools, our Mr Numbers. :wink:

[rick130]

Here's where the adjustments were originally posted. Unfortunately the diagrams have been lost with the forum going to a new owner/server.

Its not hard to adjust them all up. you need to take your time and do little changes....

First, you need an Exhaust Temp gauge, and preferably a Boost gauge too.

As OI said mine also peaks out at around 4k, from that point onwards you are really no longer in the power range so its really pointless reving it that hard. I rarely need to go above 3k, but 3500 is sometimes reached pulling up hill when in a hurry. Matt

My problem is I need to know how loud 3500 is. Is that just very loud, or is it extremely loud, or my favourite, unbelieveably loud... otherwise known as "WWWHHHHAAAAATTTTTT?" 8O https://www.aulro.com/afvb/ https://www.aulro.com/afvb/

Bahaha. https://www.aulro.com/afvb/ At 110k we could not believe how loud the car was. It was a constant throb at a level that kind of hits you in the chest. We added underbonnet soundproofing, and this helped take the edge off it.

From your comments I gather that discos are heaps quieter https://www.aulro.com/afvb/ At 110/120k, between tyre, road, and engine noise it's so loud in our car that you can listen to the radio or talk. You can't do both https://www.aulro.com/afvb/ Oh, and if you have the aircon on high, you are at the point of yelling to converse https://www.aulro.com/afvb/ https://www.aulro.com/afvb/

I don't think it's loud enough to damage our hearing, but I wouldn't want to do it every day for long periods https://www.aulro.com/afvb/
