Dont be put off by BIG mouths like this bloke, they work for some vehicles and not for others.
I put 2 in my naturally aspirated 2H diesel and made a noticable gain in power in high rev range and an improvement in fuel economy of
approx. 1 -1.5 km per litre. That was 180,000 ks ago, so at 1 km per litre saving, thats 6000 litres of fuel, and lets say $1 per litre and hiclones cost me $260 makes me $5740 better off, or I have driven 30,000 ks for nothing out of that 180,000! So even a lesser amount over the long term has its advantages and they NEVER wear out!
You have nothing to loose, as they have money back garrantee, so go for it!

I have 2 in a 2.8 diesel hilux. FACT: Fuel economy before was 11L/100km now it is avg about 9L/100km 1 year on. I have also noticed more responsiveness almost from the time I put them in.

m_w,

Any chance you can remove it again for a thousand or so k's and give us a finding?

A saving of 3l per hundred K's is er,um....well remarkable.....!

have you got same tyres as before HC?

Hmmmm...dunno if I want to mess with it for the sake of science given the price of fuel atm. I also put in a K&N air filter 1000kms ago and have the injectors serviced 3000km ago and after these bits I noticed the extra 1L/100km saving. Apart from that, I haven't changed anything on the vehicle, have continued to drive like a hoon and do my normal range of driving.

Whether or not the Hiclones and K&N are coincidental to these savings I am not sure but I am happy with the how the truck is running. You are right - it does sound like a lot but I am sure of the figures.

I had one in my old Pajero and it gave me 5-10% better fuel economy. I beleive that it worked for me.

One was installed in the surf by the previous owner, I removed it and it's made no difference to economy, however it does blow less smoke now it's out. I would say removing it increased the economy as the bloody thing was blocking the air flow more than anything.
"MAYBE" there is an advatage for naturally aspirated vehicles (can't see how) but the basic principle behind them is totally blown out of the water when it's a turbo'd vehicle as the turbo would remove any change in air flow it would have made in the first place.

I Agree! the so called "hiclone" effect is a load of rubbish. It's just an air blocker. It's quite simple, setup a good clean cold air fleed to your good clean air filter and you can't go wrong.

Yeah but they only give you 30 days. They say that it takes 300km before it starts to work. In a month if you exclude the first 300km it doesn't leave you much of a chance to get some kays up to prove it right or wrong. Remember that between every tank full you will generally get a difference of 1L/100km standard deviation in consumption anyway, depending on what sort of driving you did in that month.

So if using the device only gives you about a 1L/100km saving then you really need to test it over atleast 3000km of normal driving to work out a new average consumption before making a judgment on its performance.

I bought 2 and by the time I worked out that it didn't work then it was way to late to get my $$ back (1HZ).

Hughesy

Have one in my 99 GU diesel ute. I haven't really noticed any difference on the open road, towing the float or not towing. There is a distinct difference in 'round town driving, getting about 1.5 km more per litre. It's not a turbo model. It doesn't seem to smoke as much as it did under load ( towing etc. ) either.

There are lots of positive testimonials but the independent scientific tests I read a couple of years ago showed not difference in power or fuel economy. These things were tested by a uni in Victoria - possibly the vehicle faculty of Monash. I bought one before I read these tests and found no difference in my car. The tests confirmed my findings.

Maybe the people with the positive testimonials need to justify to themselves and others that they were not had - I have accepted the situation long ago but haven't bothered to pull it out as it didn't seem to hurt performance or fuel consumption

Cognitive dissonance is the phrase you seek.

Combined with the often united benefit of disposable income allowing purchase of proper service, new tyres, filters, etc.

Of course, only the widget made the difference...???

Individual call.

timglobal - I know the term cognitive dissonance but didn't want to use it because I was worried others like peteC wouldn't know what it was.

And speaking of peteC - little brothers should be seen and not heard - actually not being seen sounds pretty good too!! Likewise people who drive a Mitsableepty Trytoo diesel should be seen and not heard - though with a Mitsableepty Trytoo there is normally a lot of noise but not much go.

Cognitive Dissonance - A condition of conflict or anxiety resulting from inconsistency between one's beliefs and one's actions, such as believing that it is everyone's right to drive the vehicle of their choice, yet fallaciously criticising a Mitsubishi Triton.

jt
I had two fitted to my gu 4500 a few years ago and noticed absolutely no difference in power or economy. Should have taken them up on there money back guaretee, but never got around to it. A mechanic told me that they work well with older petrol and diesel engies and supposedly make the air swirl around as it is taken into the engine so as to burn more efficiently. The GU's already do this from standard. As you can tell I am no expert on motors but that was my experiece with Hicloes. Save your money for something really useful like another six pack.

A mate a while back put one on his Landcruiser -and said it improved his economy.... . (and driveability.....)
Anyway a couple of other mates and I got sick of his bragging about his hiclone so removed it one night without the owner knowing....
Some weeks later I asked him again how it was going..."Better than ever!" was the reply. "Definitely improved economy AND driveability!"

Amazing that! It's called the power of positive thinking. That's why drug tests on people have to use placebos for 50% of their patients.
They ARE a joke on 99.99999% of vehicles.
Think about it- if a small percentage of people think they work or don't get around to asking for their money back, then they make a lot of dough.

Flash - you're entirely right. Google "Cognitive Dissonance" and you've nailed their 'sales' ploy all over.

Snake Oil and Abtronic may also appear along with many other questionable things.

I have two in my 94 Triton turbo/d and made no great power or fuel improvements. But, it did make the turbo cut in at around 500 revs lowerwhich was a bit of an unexpected bonus giving a lot more low rev torque when taking off or putting around.
Ive also heard they need to be in exactly the right positions and some cars such as turbo diesels may need two, located before and after the turbo, to work. On mine the first made some little change to when the turbo cut in, but after installing the second it made the difference.

No offence, BUT ARE you really SERIOUS???
You are dreaming bigtime.... or perhaps having a go at the gullible out there.
Hiclones supposedly work by spinning the airflow to get better fuel atomisation etc.
Do you have any comprehension of how fast it is all spinning when it exits the turbo?
Having said that, I think you are just fishing- and as such you just reeled me in. The joke is on me...(Either that or you're on magic mushrooms!)

Dont know whether they work or not.

I'm finding I'm getting better fuel economy and performance in my 4.5 Patrol out of using Premium Unleaded , Caltex Vortex actually , then regular unleaded.

The Vortex is approx 6c per litre dearer then standard before the Woolies vouchers.

I didn't find anything extra in paying for the 98 RON PULP's like Optimax etc
