Wussat ?

Our 3.9i Discovery is converted to LPG. It does about 10 mpg around town and
13 MPG on a run. Seems the same on gas or petrol. We have two underslung
tanks with a filling capacity of 58 litres which gets us a bout 130 miles.
We went from Kent to Cornwall this summer and had no probs finding filling
stations, we print a list of stations and keep in the car.
Our last 3.9i Range Rover (not LPG) did about 18 mpg and our 3.5 90 does
about 20 mpg on road (off road its single figures).
Personally I would never have a diesel, just love the V8's, thats my
opinion!

mind, you can't often do that IME - they mostly don't do the cover I want
anyway.

He's actually claiming 145bhp, nearer 200bhp for the TD5. So not
quite V8 power, but still a useful bit of extra go. That seems to be
just the intercooler upgrade though - there are other things that can
be done vis a vis the exhaust I guess.

Also www.allisport.com do similar stuff.

However, the number of LPG places is still increasing, and I've rarely had
problems recently.

You should note that "Autolycus" spent a lot of time towing a big trailer -
his mpg figures are thus on the low side. I don't know what system he had,
mind.

There's a good, but not cheap (about 800 quid, I should think, by the time
it's fitted), option to increase tank space - remove the petrol tank and fit
a gas tank (80l which holds about 64l), and an aluminium extra petrol tank
inside the rear wing, which holds about 8 gallons of petrol as a reserve -
enough for about 120 miles, or more if driven carefully.

the big tank together with say twin 35s would give you a total usable
tankage of about 120l, which is more than the petrol tank holds, and which
on mine would get me about 340 miles. A 3.9, not towing and driven tidily,
would get a bit more.#

on a decently-converted 3.9, running closed loop, you should be able to get
15 mpg, mebbe more, provided you don't get silly with the loud pedal.
Should get about 180 miles on the 2x35 tanks alone, which is around what
mine gets from the 80l tank, doing about 13 mpg.

The led gauge on this one is actually quite good, but I tend to use the
tripmeter mostly. Part of the thing with gauges is making sure the gauge on
the tank matches the one on the dash... there are quite a number of
different resistances.

expensive :)

nah, seriously, I believe the bloke knows his stuff.

bigger intercooler, more boost, turn up the fuel, perhaps tinker with the
timing a bit.

Thanks for that Tim.
Hmm. Whats wrong with nipping down the breakers and fitting some
ex-commercial intercooler ? Mine is going in a 101 Ambi.

Any point polishing the ports on the (200) Tdi - mine is now in very,
very small pieces ready to be rebuilt so anything that can eke more out
that I can do now, I may as well.

People Hi,

Since I have some free time I considered it would be a nice way to spend it
adding a few thoughts on the subject of V8 v. Tdi and how to tweak your Tdi

regarding V8 and Tdi engines
A V8 engine is almost always more fun to drive and especially if we are
speaking for 3.9 or larger capacity , Efi or carburated with a good system
(see weber four barrels) .
But a Tdi is more economical on fuel and far better when asked to be used
under dump or extremely wet conditions.
IF tweaked a Tdi feels almost as fast as a standard 3.5 Efi engine or a
slightly out of tune 3.9 Efi or properly carburated one.

Tweaking the Tdi.

There are several companies and persons selling intercoolers, hybrid
turbochargers, chargecoolers, tweaking the fuel pump and changing exhaust
systems with larger bore, more freely flowing variants and last but not
least swapping air filter elements with more freely flowing ones or changing
the air induction system (air filter housing) with different ones.
Personal experience with fitting a full frontal area intercooler bought from
Allard, a hybrid turbocharger from Torque Development Engineering, a RamAir
air filter element from John Craddock and tweaking the fuel pump following
the instructions from Allard and later from the site who everybody knows
(feel free to ask for it and I post the URL but I think everybody knows it
by now) had spectacular results and up to now (since 1996 when I started
modifying the car) seems to have done no harm to the longevity of the
engine.
The power is calculated to around 160 bhp without changing the exhaust
system which reportedly gives a few ponies more and more importantly better
torque and at a lower and broader rpm range.

Another thing that has recently been introduced is the VORTEX exhaust system
which essentialy comprises of different resonators installed instead of the
standard factory ones. Those units are in fact accelerators of the exhaust
gases therefore reducing backpressure and thus increasing the velocity of
the exhaust and lowering the fuel/air mixture decreasing fuel consumption
and emissions and increasing performance on the same time.
I have not tested it myself but LR magazines having tested it report
positive comments on all the above positive and negative results on
performance and consumption/emissions respectively.

What my choice would be?
A nicely tuned Tdi engine with a good ICE system playing a V8 recording
(kidding)

Take care
Pantelis

How much difference?

I've though about removing the cat from my 110. Paddocks list a section
of exhaust without the cat and I've thought about fitting that instead.

It's only 22 quid too so I'm very tempted.

Is de-catting a 300Tdi likely to affect things come MOT time?

Do they actually test dieselcats, or do they just get a smoke test the same
as ordinary diesels?
 
all mine got was a smoke test - I don't think a diesel would pass especially
on particulates !!

It's not really a cat is it? Isn't it an Oxydiser or something? And,
in answer to your question, no they just smoke test them.

in that case, I'd pull it and tune it properly so it doesn't smoke. Should
pass easily.

Tweaks to our TDi have paid off, it's going very nicely and returning over
32 mpg average, whereas before it was doing about 29-30.

Should do - as long as it's in a decent state of tune. I removed mine
and blocked off the EGR and it made a fair difference.

32mpg is not bad at all. Especially as you live in the wilds (IIRC) so
I suspect that most of your driving is not along main roads and
motorways.

I reckon I'm gonna try removing the CAT and blanking off the EGR then.

Paddocks are about to get a large sum of money from me for wheels/tyres and
a vacuum pump so I may as well get the non cat section of exhaust too as its
only 22 quid.
