picked up a flier on the "Hiclone" thingy that claims to increase
torque,mileage and cuts emissions ???. apparently my 300 TDi will require
two @ £60 each. has I do a lot of towing wondered if worth it?? any-body
tried them or heard any comments on them, would be much appreciated.

I've seen various discussions on this in forums, and most people think it's
a load of rubbish. I have heard a few people say it makes a difference;
they usually then go off to check out the difference on a rolling road and
you never hear from them again. I don't think I've found anybody yet who's
found any hard evidence that it actually makes a difference. Any difference
seems to be psychological. But who knows.

How is putting an obstruction into the air intake going to improve power?

Older carburetted petrol engines *may* have benefitted from such a device
because it adds turbulence which might improve petrol/air mixing.

As for improving a direct injection turbo diesel engine - hah! What a load
of nonsense.

Tell them that you'll take your vehicle for a before and after dyno test. If
there is no significant improvement then you'll want a full refund plus the
cost of the dyno test. If they don't agree then tell them where they can
stick their Hiclone.

Agreed. How on Earth is one of them things meant to work on air that
goes through a turbocharger and an aftercooler before the intake
valves? Answer is that it doesn't and probably wouldn't do anything
even if the engine was naturally aspirated diesel.
Snake oil.

This is most baffling! When I moved my snorkel forward, and compromised the
design of the Safari, my mpg went down to about 9mpg with the snorkel as the
main intake! There was too much turbulance. I run with the front of the
airbox opened now when on the road, and luckily get some MPG back ;-)

So...I can't see how annoying the air prior to a turbo helps at all.
Bizzare. You can buy them for the V8 too - and at £100 I think I know where
they can keep it :)

Just to throw in my 2p worth ...

I got some of these to test on an old carb V8. HC emissions were reduced
at 2000rpm by between 30 and 40% with repeatable results depending on
whether they were fitted before or after the intake elbows. I'm not sure
what they do otherwise, that's too subjective, but I'm currently getting
over 16.5mpg out of my V8 in toodle about mode with a set in place ...
I'm about to take them out for a while and see if it makes a significant
difference.

I agree that there will be no obvious benefit to fuel mixing if the
'modified' airflow is interrupted before fuel is added (installation
before a turbo or intercooler for instance). There are other
possibilities with intercoolers such as the decrease in laminar flow and
better cooling of the charge due to the turbulent surface airflow but
that's just me thinking out loud and possibly not at all relevant ... I
also find it difficult to see how an injected engine with tight emission
feedback control could radically change apart from perhaps getting
better fuel economy due to better overall burn efficiency - torque etc
shouldn't change because the control system should alter the mixture to
compensate for the lower exhaust oxygen ...

Used in older, intrinsically less efficient engines I can see the
possibilities but in newer ones I can't.

The Hiclone doesn't centrifuge anything out, it just sits passively in the
intake hose, so it wouldn't help with what you describe above. Any crud
coming through it would have nowhere to go but the engine.

I can see why a K&N filter would allow your engine to 'breathe more easily'
and how something like a Vortex exhaust will allow a faster exit of exhaust
gas.
I think if you put a Hiclone in your air intake you will have suceeded in
putting an expensive bit of twisted metal in your air intake, and nothing
else!

I have installed a similar device in a petrol engined 16 valve, variable
camshaft, four cylinder, multipoint fuel injection engined FIAT Barchetta
two seater I used to have back in 1996 and it made some difference
especially in mid range rpm acceleration and a slight decrease in fuel
consumption.

Installing one in the intake side (right after the intercooler) in a 1993
model year Discovery 200Tdi that I also used to own back then (and still do)
has resulted in no power gains and no decrease in fuel consumption.

On the other hand installing a large full frontal intercooler has resulted
into spectacular increase in performance and torque and a decrease in fuel
consumption when the performance gains where not exploited.

Take care

A number of LROC members (Sydnbey, Australia) tried them duroing a fuel
economy test. One member had his car dynbo tested before and after fitting
the Hiclone. There was no difference. Most members found no difference
although one member claimed a significant improvement.

To me it's snake oil
