Hiclone

There has been plenty of discussion on this subject over the years.

I would suggest you do a search of the archives and see what others have had to say.

You will probably find that most people who have had any experience, including myself, will have been disappointed.

I tried them in the Patrol but was unimpressed so took them back & got a full refund. If you wan't to give them a go & are not happy they give a money back guarantee.

I tried 2 of them in my gq 4.2 efi patrol. the people advised me 2 worked better than 1..
I found the engine became dead quiet, the ussual noise of sucking air was gone when you planted your foot,, even my dlight tappet noice dissapeared.... But I got worse fuel economy from them.. I monitor my fuel consumption regularly so I know if something is going wrong..
So i took them back for a full refund... I cant say I would recommend them..
How ever my father inlaw has 2 installed on his diesel troopy and he says it has made positive improvements with fuel economy and power....

so I would try them out for yourself and see if you get the so called improved gains.. if not take them back within the time frames...

I had the same experiences as the others in my FJ 73 landcruiser.
This site says it all and I hope it dispells the myth of fuel saving gadgets once and for all ,but I doubt it.

I don't wish to sound a pompous fool (I have already had to appologise for being one) but dont waste YOUR MONEY. Independant tests have shown them to be about as useful as an Ion Drive in a submarine...It's just a cleverly engineered scam....Check out Choice magazine they did some tests as well.

You can have mine for free if you like!
As for fuel consumption and economy devices the reason that we dont have vehicles that do 200 mpg on devices like the Pogue carburettor etc is theat BIG OIL controls the US Govt which tells the world what it can do!
On an alternate feuls site I read that it is enshrined in US legislation that the fuel air ratio of 1-15 which has been the normal in carbs for yonks cannot be altered legally and that any unapproved devices are not permitted on the roads and may invalidate your insurance.
Try & get a roadworthy certy on a car with a different fuel system? Does not comply with Aust Design Rules etc. Maybe thats why we now have the previously unthinkables of twin overhead cams on each bank of your V6/V8 with variable valve timing , computers etc to stretch it a bit.
Doesnt a 1971 Torana or Kingswood with a slightly modded red 6 & room to sleep under the bonnet & no bolt on thingys & a total reco for the price of a few
of the elec. gizmos which fail on the Playdoe 4by! And of course fixable with a few simple tools beside the road!

I have had Hiclones on my Falcon wagon, and they were useless - no improvement in power or economy. Same on the diesel Landcruiser 80. Save your money for regular servicing - that will save you $$ in the long run.

Well I have to disagree with some of you I have 2 in the 2h and didnt make much difference to power but I improved my fuel mileage by over 1 km per litre. I know there are mixed results some say they do nothing and others are happy to get a result and leave them in there. They cost me $260 for the 2 in bulk club buy and I save approx 3 - 3.5 litres every 100ks. I have had them for approx 110,000 kms and at a conservative saving of 3 litres per 100ks I have saved 3300 litres of fuel at an average price of 95c = $3135 minus cost $260 and I have saved approx $2875, and tomorrow I will start the motor and drive to save again and they will still be there in 5 years as they never wear out.
Approx yearly saving on my 50,000 kms a year is $1450 - $1500, so even if it only made half that much difference to your milage if you are a long term owner then it will pay for itself down the track.

I have had a 1 hyclone for five years in a 2F cruiser. I found the low speed throttle response was improved dramatically and the highway fuel usage was reduced by .5 - 1 l per 100km. Maybe they make an improvement on older inefficent motors and not on newer ones?
