To Hiclone or NOT to Hiclone

Ok I’m going to try and evaluate the Hiclone product I bought for my 80 series 1hz diesel.
I bought 2 Hiclones, KI 63 and KI 68 . One was put in the output of the airfilter box and one at inlet manifold.I fitted the hiclones back in 2002, The cruiser had 241480 kms on the clock. I didn’t notice any real improvement in fuel economy, but Its hard to compare different trips because of the different road conditions, loads carried etc. Each time we go exploring, there seems to be MORE to take. I felt that the cruiser had a little more staying power on the hills though.

On a recent trip to WA (2004) I took very close attention to the fuel economy. I Took the Hiclones out for part of the trip, after we crossed the deserts, the bungle bungles , and the B%#@&* Gibb river road. We recorded the following figures:
Hiclones IN
Fitsroy Crossing To Mt Magnet, 3283kms /415 ltrs = 12.64ltr/100kms OR 22.356MPG
Then I pulled the Hiclones OUT:
Mt Magnet To Port Agusta 3954kms /519.75 Ltrs = 13.1449 ltrs/100kms OR 21.47 MPG (this included the Nullabor !)
Hiclones Back IN
Port Agusta to Tamworth 1617kms/198 ltrs = 12.2448 ltrs/100kms OR 23.07 MPG

If you average to Two Figures with the Hiclones In the Cruiser I end up with:
4900Kms/613 ltrs = 12.64 ltr/100 kms Or 22.59 MPG

So the way I figure it , The $298.00 I payed for the Hoclones gives me an extra 1 MPG . or saves approx ½ ltr per 100 kms.At the present $1.30 a litre, It will take me 46000Kms to recoupe the initial cost , and then Its save save save. I currently have 302000Kms on the clock, So I guess I’m I front…….I’ll let your readers decide on the merits of the Hiclone.

HI John, Know where you are comeing from. I fitted a FITCH F300 to my 80srs a few years ago my cruiser a 80srs after market turbo fitted was returning7.4klms per litre before i fitted the fitch after fittment it went to 8.7klm per litre and sometimes went to 9.2 on flat country out west NSW
.Got in touch with hiclone to evaluate their product sold the director of Hiclone a F200 for his vehicle and I bought two HIcLONES for mine
.Now after fitting both of these I have to concede no difference was noted,but to my amazment he did not respond with his findings of the fitch
.Of cource since then I purchased a new 2005 100 srs GXL turbo auto and after fitting the same F300 to this vehicle it immediatly returned fuel fig of 1113klms for 113litres of fuel which equates to 9.8klms per litre.I did not check this vehicle without fitch knowing what it is acheiving inside the motor.So now I will let you readers lament on the merrits of the FITCH.NOT advertising this product simply telling how it is with personal testing.

Kindest regards BILL

Hello John and Bill

It may be that the Hiclone works by correcting an airflow problem , if one exists , and that the Fitch is meant to improve fuel . In efficient engines [ with high BMEP ] the Hiclone should do little , but the Fitch should equally improve all engines . In my V8 Disco , the Hiclones work .

I know one thing - HICLONES are USELESS, DO NOTHING, AND ARE A WASTE OF MONEY in a 2.4 and 2.8 litre hilux. I used to drive a route regularly Albany- geraldton return and recorded the trip with and without HICLONE meticulisly(??)
Trip is around 1700km return and fuel usage was within about a few litres.
I returned it within the 30 days and was told "your the first to return one!!"

I was a little scepticle about the Hiclone after fitting two to my 3.0 TD Prado. I too concede that they do work. The results are not phenominal, but they do provide a postive effect on torque.

I had them on for about 2 years. Removed the one in the air inlet to turbo hose, saw no dramatic effect. I was still returning 10-11 L/100km on road trips. Removed the second one at the throttle body and began to feel the drop in torque.

Fuel consumption went up. I drive a hilly and winding road from the Gold Coast into the Hinterland. I found that spot where the vehicle just cruised through I now had to change down a gear.

Re-fitted both Hiclones and the torque is much better. I'm not taking them out again.

One interesting thing I found was the 120 series TD has a device at the aircleaner called a Air Intake Pre-Spinner. It looks surprisingly like a hiclone. Now if this design didn't work, why had Toyota adopted a similar concept?

Ditto. I get a very small improvement in fuel consumption but you can notice a difference going thru the revs and accellerating. The hiclones just seem to make it breathe better.
I reckon there should be noticeable differences in a carby vehicle where the hiclone has a direct effect on the fuel-air mixing as it goes past the venturis, but in an injected engine it only helps the air get to the throttle body with less resistance.
