Hi just wondering if any body has any remarks weather hiclone's realy work.
I have a Nissan patrol 4.5l petrol, i'm not wanting any more power but any increase in fuel economy would help.

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.

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.

sounds like you drive one of those crap V8 landrovers. No matter what you do it will always have the ecomomy of a Hummer.

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.

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!)
Cheers

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
