Re: black smoke = over-fuelling?

Mark Hi,

I would say that your new injectors are letting more fuel into the engine
(since they are new and unblocked and function as they were supposed to).

As for the snorkel I can only say that on my 200Tdi engined Discos it
actually assists performance and lowers the fuel consumption.
It appears that the longer induction helps on torque. (I remember reading
something about it but it is supposed to only work when the increase in the
induction happens between the intake manifold and the intake valves. Any
comment from fellow listers specialized on this topic would be extremely
appreciated)
The obvious thing though is that the snorkel lets much colder and cleaner
air inside the air filter housing when compared to the air that is usually
drawn inside the air filter from inside the engine compartment. And as we
all know colder air is richer in oxygene and therefore provides better
combustion and better performance and lower fuel consumption (if the
air/fuel ratio is not changed)
On more bonus (already quoted above) of fitting a snorkel is that your
engine will be breathing cleaner air and this will have a very noticeable
effect you how frequently you will be changing your air filter elements.
Fitting a more freely flowing air filter element has also helped a lot on
both my engines.
I keep full fuel consumption records since the day I bought my cars and the
more freely flowing air filter (RamAir) together with the snorkel does make
a difference of about 4 to 5 per cent. In order to check that I had
disconnected the snorkels in the past only to reconnect them since the drop
in performance was immediately noticeable along with the increase in fuel
consumption and the speed of soiling of the air filter element.

Two more things that have also made some difference in the way the engines
feel and perform were the fitting of the FuelMax thingy (two pieces of very
strong magnet connected with a tie-rap over the fuel line a few inches
before it arrives to the fuel pump and adding SLICK50 to the oil once every
60.000 km.
A lot of people say that those things (the magnets and Slick50) are snake
oil but my personal experience is extremely positive with them.

Take care and HTH

You could just not buy some magnets, and still get the same effect!

Mark Hi,

both vehicles were factory fitted with the Mantec rearwards facing metallic
snorkel.
I have a huge dislike for Safari Snorkels mainly because of the HUGE hole
you have to drill to the side of the fender and also because of them being
made of plastic.
My Mantec made snorkels have withstood extremely bad treatment (remember
both my vehicles are Camel Trophy evented veterans having been used on the
event itself and then as training and selection vehicles). Despite them
being fitted for 12 and 11 years now they are still going strong and have
absolutely not problem with UV sun rays etc as a plastic item would have.

----------

The ramair filter actually requires a modification to the air filter
housing's cover since the very early type of this cover was incorporated
with the air filter element itself. The RamAir (and also all other similar
types and brands of free flowing aftermarket air filters) does NOT have this
incorporated cover. So you have to remove it from the old factory made paper
type air filter element and then take it to a lathe so that they open up its
internal diameter by 0.8 of a mm. This allows the free flowing air filter
element to be easily positioned inside the cover only and you can fit it
without any other problems.

----

It seems quite a lot for a pair of magnets but those are supposed to be
extra strong ones. But I believe that a pair of extra strong magnets from a
pair of speakers would do the same. Remember that you also pay for the the
profit margin of the company producing the magnets kit, the wholesaler and
the retailer.

Take care

Is that every 60 decimal 000 km or every 6*10^4km? B-)

I'm not convinced this "magnetic effect" thing is complete snake oil,
but the effect doesn't last long so in the case of water you should
fit them on the fed to the HW cylinder not in the rising main as the
effect will have worn off in the CW storage tank...

How ever the field strengths are quite high so your average science
class magnet won't work. Maybe look at the cobalt(?) serious, have
your finger off, magnets that are on eBay?

Yes, there's nothing ferrous in diesel fuel!

Tony Hi,

supposedly the strong magnets alter the orientation of particles and ions in
the fuel's structure.
I do not know whether it is true but on the other hand it is true that they
did make a difference together with the more freely flowing air filter.

Take care

the free-flow filter is much more likely to affect things.

Absolutely sure to attract bugs.
BTW have you noticed that roses blossom much better when you throw or better
still burry a few iron nails around them????

One of the best things you can do to also upgrade the sound of your Tdi.

Actually I have first installed the larger, full frontal area, intercooler,
then adjusted the fuel pump and turbocharger's wastegate operating pressure.

Then I have fitted the magnets and lastly have installed the free flowing
air filter.

The biggest difference performance wise was noted with the adjustment of the
fuel pump and wastegate, and then with the installation of the free flowing
air filter.

The intercooler has assisted VERY MUCH in maintaining performance during the
HOT Greek summer days.

The difference (consumption wise) the magnets have made by themselves is
around 1 to 2% according the fuel consumption figures. It made no "seat of
pants" difference performance wise but the general feel of the engine's way
of operation was a bit smoother.

Take care
Pantelis

P.S. Slick 50 made the most spectacular change in the way the engine feels.
It is significantly smoother and less noisy on tickover. Some people hate it
but I use it and have used it on ALL my cars. It always makes the engine
feel smoother and more free revving than without it.
