Hi all,
just wondering has anyone had a Hiclone fitted to their vehicle?
I keep hearing about the gains in power and economy but they are all from sales people. Can get it done for $170 fitted in Brisbane.
I want to know/hear it from honest Isuzu people,…hehe
Cheers
Pissy

What is (a) Hiclone - don't know this one? How does it operate? Mike.

All a hicyclone is is a fancy deflector installed in the intake to swirl the airflow (hence the name) it has no moveing parts so wont break but wether it works or is just anouther $grabber I dont know Ive never heard anything directly from anyone useing one

A mate of mine had one fitted, he was so impressed that he fitted another, one before and one after the turbo (on a 93 2.8 rodeo). He was seemed to think that it made is truck drive better ie power and efficiency. It was normal for him to drive upwards of 500kms on a trip. I do not know the figures though.

I wonder if this is same type of product as the turbonator advertised on this site for a while. Www.turbonator.com - fitted into air intake and creating swirl effect. Mike |

Yeah mudgrip4, looks like the turbonator and the hiclone are the same thing. I pulled the following paragraph from the hiclone web page (http://www.fuelsaver.com.au/index.php) and reads for diesel engines;
“By increasing the swirl in the combustion chamber, to over three times the swirl the engine can ever naturally generate, Hiclone reduces the smoke from incomplete combustion by 50%.
Fuel savings on a new engine will be 5-10%, and on an older engine 10-20%. It is also common for customers to install extra Hiclones to non-turbo vehicles as well. On our “More Economy” page there is the “4X4 Australia” magazine test on a 4.2L Toyota diesel. They achieved 17% with one and 23.5% fuel savings with two Hiclones fitted.”<br>
Now if true, these are compelling figures to go out and get one as the fuel savings alone would pay for the unit within a year. Still not %100 sure about it but its only $170 fitted to find out and since my MU is driving around 400-450kms and tank without pushing it hard I feel I need to find ways to get some fuel economy.
If/when I do get one installed i will post my thoughts after a few weeks.

I wonder how swirl helps turbo motors because if you put a device in intake before turbo , the swirl goes straight into the turbo which my limited mechanical skill tells me moves the air faster anyway - like a fancy hairdryer. so what would be the benefit? Can understand potential effect on non-turbo, or maybe after the turbo? Maybe Peter S if you see this you could get some more data from your mate who fitted it to the 4JB1T with good effect. Worth figuring out as there appear some good stats here and there.
Maybe -as someone has suggested - we need ;D Andrew to raise some sponsor cash !!! so club can buy an old truck for us to test all this stuff on.....Mike

Fill a bottle with water and tip it upside down to drain out.
Then do it again but swirl the water around before you up end it.
The vortex lets water esacape around the outside of the opening while air comes in through the centre. This is the basic principle that the hyclone is working on, that circling air/fuel mixtures a) can move faster by not getting hung up on restrictions and b) better burning in the combustion chamber.
I don't think anyone has proven that it works, and I'm sure that certain current affairs programs have tested them without finding any improvement. I haven't had a first hand report from anyone with one either.
IMO, replacing the ribbed rubber air tube with a smooth pipe would probably improve engine breathing even more than a hiclone can.
2nd thought: can swirling the air before the turbo cause it to cavatate (it's a boating term: when the prop sucks air and stops driving through the water) or anything similar, reducing air flow through the turbo??
Cheers, Graham.

There's what looks like a Hiclone fitted to the inlet on the 4jb1t motor that I bought to replace my broken swb motor.It's not intercooled and the gadget is fitted in the inlet housing just before the inlet manifold hose.The truck is quicker than with the old motor [gains revs faster] but this could also be down to the 3l/100km of oil that's coming from the breather.Some of the oil leaks out of the turbo housing but it must also be burning a lot.Doesn't seem to smoke much on the road but makes a good cloud on startup and when I'm stuck and giving it death.Revs to about 4700 as well.One day it may just keep on going.That's a bit scary.Anyway I was going to do an after and before test on the Hiclone but the oil problem is abit more urgent.

It seems we need a volunteer to fit and test, or someone to find some hard data on these devices - may be something to them.
Harry - on your second point - blue smoke at start up, excessive oil use but not evident on the road, this is a very common Isuzu problem. Am about to buy a kit that fixes it, and as others will be affected, will start a new seperate thread on this - on breather kits. Suggest you have a look - Mike

I posted this question on the Aus 4wd Monthly forum. They think it's not the best investment. Some gains in economy, loss of power blah blah etc, all had differing views.

I spoke to a dyno bloke about these. They had done a before and after and found no gains, or losses. A bit of a nothing accessory by the sound of it.
