Thread: HiClone in 300 Tdi

where would it go before or after the turbo

Ok, so after the air is disrupted by the hiclone what happens when it gets to the inlet manifold.
What is the point before the Turbo all that disruption would be for nought would it not?
looks like it works like a boat propeller densifying the air by forcing it to twist like rope but the first bend in the pipe would undo its work.
I really don't understand hiclones and need educating.
Is it really a scam device like fuel saver drops?

I don't know, I hear good stories, and then I hear indifferant stories. I might pull the HiClone of the RR and see if it's diameter suits the Defender, then try it out and see what happens. If it fits.

Still interested in first hand reports though.

The guy with the 80 Series raved about it (more power for towing a 3 ton camper) but he said you had to have 2. Now that's expensive.

I honestly can't see a Hiclone doing a damn thing.
There are too many stories of people fitting them and finding they do nothing, which is what I would expect.

How could it make the turbo spool up earlier when it is expanding exhaust gas that drives it ?

Fitting a larger diameter exhaust reduces back pressure and helps the turbo spool up quicker. Adding fuel by adjusting the injector pump and increasing the amount of exhaust gas off idle helps the turbo spool quicker.

Adding a couple of bits of pressed tin makes the turbo spool quicker ?
Don't think so.

In a turbo engine a hiclone would do zip, the inlet charge is under pressure from the trubo already all it would do is to cause a disturbance in the airflow.

The turbo would spin the air as it went through I would think, then shoving the air through the intercooler would laminate the flow again. High pressure injectors "mist" the fuel into the cylinder. I can't see it doing a darn thing on a diesel. Now a petrol with a down draught carbie might get a gain.

Trev.

When scientifically tested at the vehicle unit of Monash University they found the hyclone made not statistical difference to either fuel consumption or power or torque curve etc.

So if you are inclined to buy one of these - please send your cheque to Gazzz in Canberra - it will have as much impact on your car as fitting one and it will make me a happy little formite.
