Thread: HiClone in 300 Tdi

and ports these days, within the realm of ease of manufacture, are designed to promote swirl and tumble, as is the chamber in the piston itself with a wide squish band, and it gets one hell of a squeeze by the CR of a diesel.

If I was still involved with racing I'd love to give one to my cylinder head bloke (one of the best in Oz) to stick on the flow bench with a head and manifold. I have a sneaky suspicion on what he'd say.......
and I've never, ever seen one on a race engine where you'd sell your own Granny for 1 measly HP.......

Look at it this way. To improve power/efficiency you have to either provide more air, more fuel or optimize the combustion process. A Hiclone doesn't do the first two and the combustion chamber shape isn't altered by fitting it.

As Zook said, there may be a benefit in older carb engined vehicles with poor manifold and port design (most did) that resulted in fuel pooling and puddling on the manifold and port walls, buit this doesn't happen on a diesel.

waste of time i put the two in my 130 300tdi and found bugger all difference, called them after 2 weeks and said no good, they said give it another 2 weeks, i did, and sweet F.A. took it back and got my money back.

they have a money back garantee, so wack them in and try for yourself, if no good yo can simply return them for a full refund

To get this on a diesel such as the TD5, I believe you would need five of them, one on each of the inlet manifold ports!

Trev.

even if you had 25....i dont think it would make a difference.....as once the air is compressed
all the swirling would have stopped......then the fuel is injected.....


if the fuel was mixed in with the air before it gets to the cylinder...then possibly it may make some
sort of difference....it may mix better due to the swirling.....






now if you push air through a fan......is the air actually swirling....?
the way i see it....the air is flowing in a straight line.....the fans blades will spin.....
but they wont make the air spin......

to spin up the air....you will need fixed vanes for the air to flow through.....
so they can change the direction of the air.....

These are the biggest con out there (except maybe Brock's black box). All independent test I have seen show no difference in performance or efficiency of any engine. Don't you think if it was that simple the Japs would be doing it. It would cost $1 to put it in during manufacture.

GUYs this is just a con, con , con. Don't waste your money. Please!!

However, if you are realy interested in something that works.........

Sorry, I wont go on someone might accually beleive me and want to buy some snake oil from me.

That's what I was after, first hand reports!!! Thanks.

The best I have seen is one fitted into the tailpipe of a 110 TD5. WTF is it going to achieve there?!

higher exhaust gas speed for inflating the air jack
