hyclone

Your the first person Ive heard of thats had ANY sort of + result from them...

Try the archives, its been done lots before, but dont know about in rodeos.

How do you find it? I had a 2.6 EFI TF 1990 mod, that was OUTSTANDING! Would love another..

I found one of these dodgey con tricks in a 4WD display at our local outlet. It had a fan being spun by the hyclone gismo. You were asked to put your hand over the top to show that it stopped the fan. I took the device out and put a couple of fingers over the outlet. Same result..... I think this is one of those come-in-sucker devices that needs the two fingers! But as always I could be wrong. Royce www.funshow.com.au

these things are designed to spin the air before it gets into the motor, i have a snorkel on my patrol and the head has groves in it to let the rain run out of the air being sucked into the head, this is done by the natural suction spinning the air thus throwing the water to the edges and draing the water out so i dont need a to pay for some fancy piece of art that does nothing and has been scientifically disproven. Come in spinner. Col

Shorty.. I asked my local 4wd Service man about Hyclone at the last service on my Jack, and he told me that it already had something similar as standard. This has been confirmed by Saavas on a Question on this site about a month ago. Have a look in the archives under Hyclone. As the Rodeo and Jacks are all out of the same stable you might already have one in it. I was told that Hyclone don't make much difference except to the wallett.

This is a subject that comes up quite often on different 4x4 forums and there is usually a divided response some swear by them some believe they are nothing more than a con . But what i have noticed is that they do offer a money back garauntee which from the stories i have seen has been honoured without question. So i say if you had a good experience before give it a go again if its no good send it back and get your money back. Nothing ventured nothing gained.

to add to my original question i had a vn commodore for 10 years that for the first 9 years got a consistent 10 ltr/100km on the highway. after fitting a hyclone it got 9.2 to 9.4 ltr/100km with the added advantage of turning the lumpy idle into a smooth idle.I have had the habit of monitoring my fuel consumption on every tankfull so my result is not based on one trip.I can only judge it on my experience.I only bought it after talking to other commodore owners and hearing their storys this is why I would like to hear from rodeo owners who fitted one to see if there is any advantage in fitting one to a rodeo.

All the Current affairs shows have done tests on them, and none were favorable.. this is from ACA site.

No I dont hold spit on them shows usually, but heres a good quote from Ford Melbourne Emissions laboratory, the Head of the lab, John McEwan

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
But John McEwan is still doubtful.

"Companies like ours spend millions trying to improve fuel economy but you don't seeing us fitting those sorts of devices. We've got massive research facilities around the world. It's not only Ford but it's the rest of the manufacturers, and you don't see them using them," he says.

Fact of life,,air blown or drawn down a tube with a bend and or rifling will swirl as the Hyclone supposedly does,, ,,,, have yet to see any dead straight air intake on any factory engine,. ,,,Jet engines excluded.
Have a good look at your rodeo air intake "canister" , you will find that the end cap is designed to force the air into a circular motion.After the air filter,bends and or grooving continue the swirl/rotation.

My understanding, is that these units are made in third world countries, so the cost to make and import should be very low. If there are any benefits, it will take a long time to get your money back, as the are normally fitted as pairs.

I suspect that any improvement, could be attributed to the driver making them work, by treading a little more carefully.

Also on turbo engine, I cannot see how they work.

If you are chasing fuel effeciency, then only buy cars with a common rail injection system.

Lastly these units cannot be fitted to all cars.

after reading heaps here about hiclone i asked our local hiclone rep if he was prepared to do a dyno check before and after the hyclone was fitted he told me he dosnt have a dyno so i told him ill set one up been a cpl of months now hes either to busy to fit it and get it checked or scared of what we will find out.looking foward to easter at jamieson

Fuel economy is a very big selling point these days.
IMHO the manufacturers would all fit them if they worked!
They definitely could do nothing for a turbo- the turbo already spins it at thousands of RPM.
