Anyone had any experience of Hiclones?
Discussion
I'm interested in anything that improves performance/economy or both.
I've recently heard of this gadget called a Hiclone which (according to the blurb on the website at http://www.hiclone.co.uk/) can improve both.
It supposedly achieves this by causing the air in the inlet tract to swirl around. It looks just like a non-moving fan that you insert in the cool air ducting.
Can this work? Is it worth trying?
Any advice greatfully received.

No it can't/won't work.
It'll cause more restriction than a standard unmolested intake tract.
Swirl/Turbulance in anything other than the last few CM of the inlet tract (for fuel mixing) is a waste of time in 99% of circumstances.
If it did what they said it'd be installed as OEM.
Basicaly its snake oil.

Read the test results and decide for yourself.
Keep in mind that the power tests are done on a rolling road, which can easily vary 1 or 2 percent on the same car on the same day when taken within minutes of each other.
Fuel economy tests based on mileage tests on real roads are also subject to significant variance (easy 10% in the case of my identical daily journey on my motorbike which is less subject to traffic conditions than a car).
Most of the quoted improvements on the web front page seem to be taken from very low RPM on large capacity diesel engines.

Hiclone(V.):
Snakeoil. See ecotek valve.
"Hiclone has a positive effect on Turbo charged engines in that it facilitates the turbo to spool up to speed 600 rpm earlier. Where possible, we recommend a second Hiclone is fitted to enhance turbo performance, increase low down grunt and torque in the lower ranges. This is particularly effective on low revving engines."
