Title: V8 vs TDI
Post by: Diamond Hell on 09 October 2011, 07:55
Everyone loves a TDI for the economy.

My mate who races off-road loves spending under £30 on fuel to race, when the V8 boys are spending £120+

It's a tough one, but here's a little video to help you when thinking about the hard cash:

PAUSE :grin:

Still can't beat the sound of those V8's when they're charging past you  :drool:

I miss my V8, sounded awesome. 13mpg around town and 20 on a long run, I don't miss that part of it.

There was me expecting a debate about the v12tdi R8 vs the v10 R8

My boss has a 76 Landy with a 3.5 V8 in it running edelbroch manifolds Webbers and high performance cam, it is also custard yellow :grin:
It is such an awesome sound and was the snow mobile which took us all to work last winter.
If he gets 15mpg it of it he is a happy man :shocked:
Nowt wrong with a tdi though, and in a landy or the like you dont mind sounding like a tractor :grin:

He was planning to put another 3.5 v8 in it which he has built in his workshop but came upon a 4.6 V8 from a 96 vogue, this will be fitted next month :cool:
He is hoping to get better economy by using the efi injection system from the donor car, trying to find out how to do this properly atm without throwing up fault codes or running in limp mode.
It looks entirely possible but space and electrics on a 76 landy are limited and rudimentary respectivley. Would be a shame to have to run carbs on it so currently looking for some input from a man in the know........

Tell him to keep it carb and convert it to LPG the kits for carb based 3.5's are cheap as chips as there is no igs system.Its worth a thought :)

Its more about having a 4.6 over having an economical 4x4, when its not mud bashing he is towing a steam engine around on the trailer. Compared to owning a TVR Chimera the Landy is cheap to run even in its current state :grin:

the 4.6 will  probaly f**k up and go pourus ( provided it hasent allready )as they have a habbit of doing that, as for the fueling  the rover EFI is pants as the ECU is sh!te wether you have the flappy or the hotwire airflow meter.

it needs a trigger wheel shoveing on the frount  megasquirt II driveing EDIS 8   :smiley:   dosent exactly make the engine  much more economical but makes it more bearable as it goes rather than just makeing lts of noise also the inlet manifold can be adjusted in the throttel body department for extra noise and goes.

so is there much you can do for easy power on a tdi discovery ones a tdi 200 and ones a tdi300? don't know anything about them apart from they're really really slow on the road. Can you remap diesels that old? or turn the boost up or anything
i'd sign up to a lr forum, but i dont really care that much tbh  :grin:

Being a cityslicker for my whole life, the idea of driving around in a field seems odd. Fields are for cows, festivals and being out of your box in if you ask me.

Advance the timing and turn up the fueling, as well as various other tricks, like when and how much it's enriched.

Given that motorsport has been taking place all over the country for over 50 years you'd be very wrong.  Maybe you should come out of the city and have a look around - you're missing a lot.  Also Salisbury Plain isn't a field  :wink:

Cheers DH,

Is there anywhere i can find a eee-jits guide to tweaking disco's?

I know about motorsport round the uk, but over fields/hills offroading seems pointless to me, but i'm a wet lettuce when it comes to getting cold,wet and dirty  :lipsrsealed:

I presume you have never been offroading before then? There's a lot more to it than driving around a field being cold, wet and muddy. It can be very technical and demand a lot of skill behind the wheel.

You should give it a go!

You'll be surprised how much fun it is being on the verge of tipping over driving along a 45 degree sideslope or hooning it up a 40+ft steep slope or even clenching your butt going back down it   :wink:

You will get just as much of an adrenaline buzz at 5mph than you do round a track at 100mph+  :wink:

disco tuneing

turn the boost cone round, tweek the smoke screw. = go faster lots of smoke

fit bleed valve get more boost = more goes and less smoke.

then fit bigger IC as the LR one is sh!te = more goes better economy.

then add PROPANE = more goes and more revs

fit a bigger turbo to use all that lovely propane up.  = more goes and a bang at some point

i've been to a few pay and play days with my little brother, and a bit of greenlaning.

probably do need some skill to do it well, but its just not for me.

Cheers Danny P  :cool:
