Hyclones

Does anybody have any thoughts on Hyclones are they any good or just an expensive gimmic.I was quoted £60 for 2 off these little metal buggers.It started when I mentioned That i was going to uprate the intercooler on my RRC 300tdi as i had seen 1 on ebay made by alisport.I was told they increase bhp but obviously not as much as fitting a uprated intercooler.

Yip, they're great, buy at least twelve.

Dont you think that all the manufacturers would spend 20p on them if they were any good ? I'd rather spend it on booze or naughty women.

An dunt fergit t buy some "C'Lit" water treatment while yer on !

Ooooo, I likes a bit of that.

I take them to be a pile of shyte then !!!!!!

We know how yer produce that Tinny & at 10cc a pop, a litre's gunna tek you............er, a week.

But an Alisport uprated intercooler is worth the investment ?

(shows how stupid he is by asking what a hyclone is)

what are hyclone?

I belive that they are circular metal things that go in you air pipes.(not human air pipes !!!) and they twist the flow of air, something like that but it does,nt matter as they are shyte.!!!!!

yep i know now, i remember, they meant to create some sort of vortex in the induction system and it improves airflow hence power! i obviously forgot about it due to it being rubbish...........

I fitted Hyclones to my RR 200TDi and did some road testing to check if it worked. There was a significant improvement on bottom end (off boost)pulling power but I lost some at the top end where I figure it was actually hindering airflow. 0-70 through the gears was about 1.5 sec slower but it took 10 seconds off 30 to 70 in fifth gear. Other in gears proved a loss at the top end with smaller improvements at the bottom end. Can't say what difference it made to economy as shortly after fitting, my RR spent most of its life off-road.
I installed them as instructed, one before the plenum and (against my better judgement!) one before the turbo (this one makes absolutely no sense to me as the principle is to introduce swirl to the airflow. Like the turbo is not going to completly wipe out the influence of that one!).
The concept has merit for older engines with simple intakes but most modern engines have swirl engineered into the head so its a complete waste of time on anything after a 300tdi (and I'm not even sure about the 300).
My honest opinion is that for £50ish you can measurably improve the bottom end of any older technology engine. Thats either worth it to you or not.
As I said above mine spent the rest of its life off road where bottom end is more important than top so I got a useful improvement and I left mine in and consider it money well spent. I probably should take out the one before the turbo and sell it on to anyone who wants it!
