hiclone

[Toad]

Thinking of buying a hiclone system for the troopie and a k & n air filter. Checked out the web site and talked to a rep in brisie, sounds good but is it to good to be true. Just after some feed back.

[BigBugga]

I have often wondered the same thing.
Was going to try one out but have been told they won't work if a snorkle is fitted.
So for me they are a no no.
Let us know if they make a differance but.

[Lotza MUMBO]

I used to be a dealer for a similar product(Turbo Fuel Miser) and the only vehicle i have honostly seen an improvment on is a non turbo 1HZ 75series landcruiser.I had a guy in north western QLD that would buy 10 of these a month from me and this was the only vehicle he was fitting them too with a noticable improvment.

[Strider01]

Hi Toad,

I'm thinking the same for a Pathfinder and the general input from people is either they do or don't work. I understand they give a money back guarantee so I'm going to give them a go. Worst case they don't work and I send them back. Something to think about anyway.

I had hiclone fitted to 4.5 GU and in my opinion it didn't work so I got my money back.(dealer did try to convince me to install 2 of them as they work better in pairs,which I didn't buy)

[Caiden]

I spoke to a mechanic about a hiclone, and he said that tests he had done on a 4wd dyno proved that you get move kilowatts when the hiclone is NOT fitted. Apparently it starves the engive of oxygen therfore slowing down the combustion process resulting in a loss of power.

BigBugga I was informed by this rep that you can also install one into your snorkle, thus increasing your power and decreasing fuel consumption etc. This was inconjunction with a hiclone also fitted to aircleaner, so maybe something to look into.
There are some good comments in the hiclone web site section.

[BigBugga]

I did ask a few people about the snorkle thing and also had a look at the web site's.
Also called the toll free number.

All in all the answers I got could not convince me to rush out and buy one or even two of these unit's.

So for now I will just run the snorkle and my foam filter. ;D

[baby_troupe]

I won't use one.
Seems too much like Snake Oil to me.

[RobertM]

Father in law tried one in his 91 Troopie and reckoned it didn't make any difference.

[RobertM]

He was told that if you install more it will make a difference but he wasn't willing to hand out even more to see if another on worked

[GQ GUY]

Have a Hiclone and a Finer Filter fitted to my Patrol (were both on it at time of purchase)
Do not think that it has made any real difference.

Have you run it with out the Hiclone?

Would be interesting to see comparision figure's from someone who hasnt had to pay for the unit.

[GQ GUY]

I havent but suppose I should now that some are saying that performance drops.

Have just had a new exhaust put on last weekend.
Will need to get some figures from this fix and then try without the Hiclone.

Will keep you posted.

[BigBugga]

Shal be an interesting opinion me think's

[Toad]

I'd be very interested in your results GQ GUY.
I think I might just get myself a good quality air filter, any suggestions?

[BigBugga]

Finer filter fit's damm near all unit's and have a very good product.

I have one in my Disco and have put one in every car I have owned in the past.
Alway's been happy with them.

[Toad]

reasonably priced?

[BigBugga]

The one in my Disco cost $70 from my opp/lock shop.
Came with a bottle of oil that lasted for ages.

Good value.

Wouldnt run a car with out one.

[Toad]

I may have to pop into opp/lock tomorrow. Probably be a good idea for this W.A. trip comin up.
Tanks Big Bugga.
And hows the weather over there at the moment?

[BigBugga]

Damm cold :-[
But still a nice part of the world.


Which part of W.A are you visiting. ???

[Toad]

Perth first. Then Carnarvon via Kalbarri & Shark Bay.
From C'von up to Exmouth via Coral Bay & Ningalloo. Maybe up to Dampier/Karratha.
Then inland to Mt Augustus also have a look at Kennedy Ranges.
Back down to Perth For a little while.
From Perth down to Margs, Manjimup & Pemberton.
Will finish up in Esperence.
Just a little driving.Cant wait, we leave next week.

[BigBugga]

Damm all the good bit's in one go.

You will pass right through my area as well.

PM me if you want to meet up and have a break from the road.

[Toad]

Cool just might do that. Thanks Big Bugga.

[cookie monster]

on the topic of air filters.
i was speaking to Reinhard @ Berrima Diesel the other day regarding the GU 2.8td motor and he recons to only use paper air filters on this motor.
anybody had any experience with other filters on this motor?
he also said not to use fuel cleaners as they wash away the lubrication from the injector pump. only quality fuel should be used as this provides the only lubrication on modern electronic diesel motors.
any coments appreciated
cookie monster

[BigBugga]

By fuel cleaners, do you mean the additives?

If so then I agree in part.

Best thing you can do for any engine is to only put in good clean fuel, problem is this isnt always possable.
My Disco always runs better on Premium fuel, but when I am away from home Premium jumps up over the $1 mark down this way.

Also some of the smaller town's have fuel that sit's for a long time as they dont have a high turn over of customers.

Some of the additives wont do a thing but then a few of them will clean out the system after some bad fuel.

I used one a while ago, cant remember the name right now, and the directions asked for a small amount to be added to the fuel when filling.
Took two fills for any differance to be felt.
Smoothed out the idle and take off, cant really say it helped my fuel economy as I didnt record any of the numbers.

[RobertM]

Finer filter fit's damm near all unit's and have a very good product.

I found out finer filter went bust but Uni Filter bought a heap of their old stuff as far I have found are pretty much the same I can even use my finer filter oil I had on the uni filter.
You can even mail order if you want to
http://www.uniflow.com.au

[Bundy]

I used to have a 40 series swb my inley hose split so I went to get a second hand one and it came with 2 hiclones. I did notice a small difference but not as much as when a fitted a larger exhaust system. I wouldnt buy new arent they about $120 each? not worth it for minimal improvement.

Finer Filter and UniFilter are virtually the same thing, although Uni's have always been better quality & hold together longer.(Had one in an old falcon ute for fourteen years-can't ask for better value than that) ;D
Dude that started Finer Filter worked for Uni Filter for a while then went solo. ;) Didn't know they'd gone broke though. :o both Uni and FF oils can be used in either filter, as can Amsoil filter oil; all the same compound. ;D ;D

[BLU-125]

When I go into very dusty areas I fit a Uni Filter sock in my snorkel, which I clean daily. I always use Rock Oil water soluble filter oil as it makes the cleaning job easy wherever you are.

[glenno]

There are a lot of half truths around whether or not they make a difference.

Funny enough i pulled the air intake off a Mitsubishi Challenger and it had a Hiclone like fitting on the end of the pipe before the air filter.

So i doubt that a Hiclone would help any more in the Challenger.

[bbushy]

We put our Gu into Berrima not long ago and as you said he swore by the paper filters and convinced us to go with one. But when we got back to Melbourne we were talking to a mate of ours who is a specialist diesel mechanic and he said that there is nothing more detrimental to the motor. He also said not to use additives but that you should run a bit of unleaded through it every now and then

[mud magnet]

A navara came into the workshop the other day which had two Hi-clones fitted i had asked the customer what he thought of them his reply was i cant tell the difference.

If this is a deisel i would suggest you not run Unleaded in it. But if you insist then i want to see the pics of the pistons and conrods after :o :o

[baby_troupe]

Me too. ;D

[cuttin loose]

not sure on this one, but wouldn't putting a little bit of unleaded into the diesel be like putting a bit of metho into your unleaded???

just another way of cleaning out the crap in the engine???
;D ;D ;D

G'day Toad
Interested to hear about your trip to the West. Don't know how much time you've got, but perhaps you might be interested in the following suggestions.........
1. Steep Point / Zuytdorp Cliffs and associated beaches certainly worth a look. I go up at least once a year chasing Spanish Mackeral off the cliffs at Steep Point. I've also been over to Dirk Hartog Island - magnificent, but expensive to get your vehicle across on the barge from near Steep Point.
2. Coral Bay - Exmouth - drive north along the coastal track - Yardie Ck and many terrific beaches worth a look - you can camp at a lot of the beaches, but approval required from the Ranger. Great fishing and snorkelling along the Ningaloo Reef. Try and get up into the Cape Range - a couple of good walking tracks.
3. Kennedy Range - a track actually runs down the centre of the Kennedy Range and exits at the southern end on the banks of the Gascoyne River, which is wide but dry at this time of the year. I've only ever accessed this track at the northern end via Mt Sandiman Station (approval required), but imagine you can also acces it via the station country on the western side.
4. Mt Augustus - bigger than Ayers Rock! It's a terrific climb, but will take about 6 hrs return, but well worth it.
5. You mentioned Dampier/Karratha as possibilities, but didn't say anything about the Chichester or Karrijini Ranges/National Parks - fantastic spots. If you want any info on these, let me know - I've been there many times and know this country pretty well and never get sick of it. I reckon it's one of the best areas in Australia.
6. Margaret River etc - many terrific spots. e.g. mouth of the Donnelly River is just one.
7. Esperance - magnificent coastal scenery west and east of the town. A suggestion if you're heading back east from Esperance..........drive east out past Cape Le Grande, Cape Arid etc and follow the track to Israelite Bay - then drive around the Bay on the beach (or on the track at the back of the beach if the weed is bad on the beach, which it might be for the first bit) for about 80kms to where the Baxter Cliffs start - about 7 kms before the cliffs a track goes up off the beach through the dunes (might be a bit difficult to find) and then up what's called the Wylie Scarp (sandy, not rocky) to the top of the plateau and links up with the old access track for the original overland telegraph line - keep following this east to Toolinna Cove and then head north to Caiguna on the Eyre Highway.
Alternatively, head east from Esperance to Cape Arid and then north past Mt Ragged (also worth a climb) to Balladonia on the Eyre Highway.

Hope this helps - let me know if you want more info, especially about Karrijini which I reckon should be a must see.

[motorschool.com.au]

We do driver training and tours. I have been sceptical of the Hiclones, one of my Instructors fitted one to his GQ 4.2 diesel with no result. BUT last year on a Cape York tour I had 2 identical Nissan 4.2litre GU Turbo Diesels. One had 2 Hiclones and no snorkle, the other no Hiclones and a snorkel. The GU with the Hi Clones had consistent 10 - 15% better fuel iesel on a few runs and see how they go.

But the GU on tour has made me have a more serious look at them.

[baby_troupe]

May have been tuning too or roofracks.
That can make a substantial difference.

[Pete]

You'd be better off just giving your money to me!.... ;D
The filter is a good one tho...

Cheers Pete..

[Bikie]

not sure on this one, but wouldn't putting a little bit of unleaded into the diesel be like putting a bit of metho into your unleaded???

;D ;D ;D

wouldn't recommend putting any fuel other then diesel bought from the pump in it, this reminds me of one of my mates petrol corolla engines, we rebuilt it rings, bearings, new pistons, the engine developed low oil pressure after about 20,000 klms, apon stripping the engine I found the bottom end bearings to be very badly worn. couldn't work out why until I was speaking to his dad later the same week who thought it was quite normal to run the engine for a couple of mins after you've dropped the oil while servicing it so as to remove any of the old oil that is still in the oil pump, galleries etc.

Sorry but it blew my mind away as to how naive some people can be. He had always had his car serviced at a workshop until about 18 months ago when he started doing his and his sons car at home. It's a wonder his pintara still bloody runs!!

[BigBugga]

CRINGE :o

[tiggr]

Snake oil and the elixer of life for sale with every hiclone , roll up roll up

[albie long]

Hi,
there has only been a slight improvement in fuel economy, what I am pleased with is the improved Zip to my Prado 3.4 manual (two hiclones fitted with safari snorkel) :)
Acceleration is better and also provides me with better revs when in sand

[Troopy93]

2.4 ltr lux 1 hiclone no difference, always put 2 ltrs of unleaded to 80ltrs of diesel , never had to change or clean injectors yet. Works for me and has done for over 340,000km.. doing the same with the Troopy but no hiclone..

[yay.]

It's all in the head. I've had the hiclone fitted in my vehicle for over a year. Recently I had removed it, and although not much difference was noticeable, the vehicle had better top-end power (tested multiple times on the M4 from silverwater to Penrith and back..) It *keeps* at 110, instead of the past hiclone-induced struggles to 100...

Upon adding a finer-filter (no snake oil here), the vehicle now *accelerates* past 110... The only catch is that it only accelerates when the filter is very clean..

It is also worth noting that it is truly essential that if you are dumb enough to purchase a hiclone for your vehicle, that the mechanic fits the correct hiclone. The first hiclone fitted to this vehicle was totally incorrect. This resulted in a myriad of problems, as the air was highly restricted.. It acted like a 90-dollar full-time choke. So, make sure the mechanic does not choose one that *will do* for your vehicle, but actually looks in the catalogue for the right part.

Oh yeah, and being a WA boy myself, it is highly essential that you ignore all your WA friends saying that it works, because basically they don't have a clue. I'm sure they're getting paid to promote this silly product.

Think of the money (and fuel) you will save by not purchasing this fraudulent product. You would want the least amount of obstacles possible for the air to get to your engine. Not buying the hiclone is removing one extra obstacle. Putting that money into a good air filter is money well spent

[genie4x4]

I was looking at installing one until the expert told me i would need 3!!!
It seems it needs one at the top of the snorkel and one on each side of the turbo...sounds a little too much$$$ for the small amount of benefit...try a magnet around your fuel line first they seem to promise the same cost savings and benefits

[mcnabd]

Mate of mine has 2 in GQ Nissan and swears by them I have 2 in 75 Cruiser and am not convinced. I will try taking them out and see what happens.

[Pitbull]

I have 3 fitted to the turboed 2.8 Hilux

1st one is fitted in the airfilter housing towards the Turbo, this apparently is suppose to cause a primary Vortex

2nd one is about 6inches before the Turbo and is suppose to accelerate the Vortex and so even assist the Turbo and bring it in approx 500rpm earlier

3rd one is in the inlet manifold

Now would you like to know what all this has acheived as far as Power and Economy is concerned ?
Im still waiting for something to happen as so far Nothing noticable has happened .

[Don]

Suggest you may need to use a polariser (peter brock type) in conjunction with 3 hiclones to achieve desired results

Regards Don

[Eddy]

;D

[Fenring]

There was an article in the mag a few months back about these. They put one in, and got a little better economy, but less power and torque. Then they put another one in and got even better economy, but still lost a little power and torque. That was on a diesel wagon of some sort, and they had a dyno to test it on. Hiclones are $160 each, too steep for me. That buys extractors / shocks / lights / tyres etc. I also remember a fine device from a few years back called a 'spirolator' that folks stuck on their exhaust tip. It also had a spiral pattern, and the same sort of claims were made for it.

[gettin dirty]

The Hiclone in my opinon is
A) a marketing scam
B) wrong theory in princial

A) as far a marketing scams go, telling the consumer to purchase two and mount one before the air cleaner and one after is having one tow bar hitched behind another.... useless.
The principal of making the air form a spiral is correct, no arguments that the desing will do that. However putting one infront of the aircleaner is pointless as once the air is sucked through the whole spiral effect is lost.

B) As far a placing it in the intake tract, the air will spin, but the effect greatly reduced once reaching the throttle control mechanisms. Further more any residual vortex motion will be significantly reduced once it reaches the runners.

For the theory to work most effectively, the device would need to placed in each runner for each cylinder.

[Pitbull]

That is the best explanation i have read so far and it makes sence.

[Fenring]

Why don't the manufacturers put this sort of thing in as stock? Then again, why don't they do a lot of things..... ???

$160 is a lot of shekels for some pressed tin.

[BigBugga]

That comment has been thrown out lot's of time's and not just about the pressed tin Hiclone.
Fuel saver cell's for example, if they are so good why dont the car's come fitted with them.
