PieEater3142 Posted February 16, 2012 Share Posted February 16, 2012 Does anyone know if these are just gimmicks or actually do anything useful. Just found one in my 200tdi 90. Should I stick it in the 110 when it's up and running or leave it be? Cheers, James Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted February 16, 2012 Share Posted February 16, 2012 So a turbo whirling round at thousands of RPM isn't going to swirl your air enough / completely cancel out the effect of a bit of bent tin mounted on the snorkel...

ejparrott Posted February 16, 2012 Share Posted February 16, 2012 I think this has been covered many times before...if its so good, in the drive for ever more stringent emmsions requirements why don't the manufacturers already fit one?

landroversforever Posted February 16, 2012 Share Posted February 16, 2012 There was a seller on ebay I wound up by asking questions about how it was going to improve my fuel economy, and what was the turbo doing if the hi-clone was going to swirl the air. :rolf: Quote Link to comment Share on other sites More sharing options...
sean f Posted February 16, 2012 Share Posted February 16, 2012 As the others have said if it was that simple the vehicle manufactures would have been building them into air intakes for years. A similar thing built into the air intake system during manufacture would cost pence extra and if there was any noticable improvement they would do it especially at the higher end of the market and commercials expected to do big miles. In a engineering sense laminar flow is what you would want to shift more air with less pressure drop not turbulant. Never made the calculations but I would expect the flow is high enough for the bore that it is always turbulant in an air intake and exhaust system, (possible not on tubular headers?).

FridgeFreezer Posted February 16, 2012 Share Posted February 16, 2012 If you put the pseudo-science hat on that they use to market this stuff, there's surely a risk that the hicolne will swirl the air the wrong way and stall the turbo There is a grain of truth in the theory, and BMW fit little bits in their inlet manifolds that help provide swirl (and fall off into the engine and get eaten). But a bent baked-bean tin is probably not going to help. Quote Link to comment Share on other sites More sharing options...
stuck Posted February 16, 2012 Share Posted February 16, 2012 Now now Fridge, That would only happen if you fitted it upside down Love the Snake Oil poster by the way. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted February 16, 2012 Share Posted February 16, 2012 I've never seen them market anti-clockwise ones, hands up who knows which way their turbo spins? Quote Link to comment Share on other sites More sharing options...

How very dare you pollute this thread with potentially accurate factual information! I had one in my dashboard for a few months, worked pretty well at cutting your fingers when you dipped in for screwdrivers etc.... Will.

Tanuki Posted February 18, 2012 Share Posted February 18, 2012 Given that the intrinsic tendency for things to swirl is different in the Northern and Southern hemispheres [the Aussies see the water circling the plughole the other way to us Brits/North-Americans], do Hiclone provide Northern- and Southern-Hemisphere versions of their swirl-inducing product? Fitting a left-hand-swirler in a right-hand-swirling hemisphere could possibly result in a horrible explosion... --Tanuki. "This beer is only 3% alcohol. That's not beer - it's homeopathy!"

landroversforever Posted February 18, 2012 Share Posted February 18, 2012 Surely as the pipe on on a horiontal plane... being above or below the equator would make the air flow a different direction? Quote Link to comment Share on other sites More sharing options...
PieEater3142 Posted February 20, 2012 Author Share Posted February 20, 2012 lol thanks guys, it did look like an expensive waste of money but seeing as how i never bought it i didnt much care. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted February 20, 2012 Share Posted February 20, 2012 It'd be interesting to do some mpg comparisons, as you've got it....I'll bet you see no difference with it removed... Quote Link to comment Share on other sites More sharing options...
tacr2man Posted February 21, 2012 Share Posted February 21, 2012 To answer the thread question Hiclone in a 200tdi - does it do anything? the answer is yes 1. It makes money for the vendor 2.It helps support the delivery businesses 3.It increases the gross weight of the vehicle dont think it does much more ?

Chicken Drumstick Posted February 21, 2012 Share Posted February 21, 2012 I think this has been covered many times before...if its so good, in the drive for ever more stringent emmsions requirements why don't the manufacturers already fit one? Not that I'm denying what you are saying, but I'm not sure it's a truly valid argument. Manufacturers build cars to a standard dictated by cost and time to assemble (and other factors). If this standard can be met, then they won't add on extra bits even if they do offer benefits. And it can be summed up as a cost thing really. For example, if a car maker builds 200,000 cars per year and they can meet the 'standard' without such a device, then why would they spend the extra to add it? Even if the cost price plus labour to fit it was say £2-4 in total, over 200,000 units tha'ts £200,000 - £400,000 lost profit. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted February 21, 2012 Share Posted February 21, 2012 From the other side of the argument, where cost is not an object, e.g. Ferrari, Porsche, Bugatti Veyron etc,do they fit them? I doubt it... Quote Link to comment Share on other sites More sharing options...

I doubt it... Tis true, although even at such levels you'll still often find them using paper element air filters and not synthetic weave ones, despite the later out flowing, out filtering and out lasting paper elements. So maybe they still don't 'optimise' everything despite the profit margin. Quote Link to comment Share on other sites More sharing options...

simonr Posted February 21, 2012 Share Posted February 21, 2012 You are all very cynical! I think you would all benefit from one of these:http://www.ebay.co.uk/itm/Orgone-Tesla-Radionics-Activator-Quantum-Shield-Pyramid-/260818650487?pt=UK_Metaphysical_New_Age&hash=item3cba00c577 to help balance your humours and chi! If you sit one of these on your engine, apparently it will run on pure b******t! Looking at the pictures - I now know what to do with all the swarf from my Mill!
