hiclone is a performance enhancement. Points say increased torque, improves mileage,cuts emissions. Hiclone is a simple non moving stainless steel device that sits inside the air induction system of the engine. Like a static mixer, it vigorously swirls the air. The swirling effect improves the fuel/air mixture promoting more complete combustion. Hilone increases torque, improves fuel consumption and cuts hydrocarbon emissions: in particular smoke. Fit hiclone in front of a land rover turbo charger and feel the difference. It improves low grunt, acceleration and reduces tubro lag. Hiclone can also be fitted to non turbo diesel and petrol engines, feel the difference! Hiclone also smoothes out the engine torque curve, resulting in a reduction in gear changes and a quieter engine especially on the motorway. With hilclone fitted you can corner in higher gear, can corner in a higher gear, this makes the vehicle easier to drive and improves the ride. Does it work would like to no figers and improvements?
 
Hi, looked into this and for the RR we need two, one pre- and one post the intercooler. Supposed increase across torque is 5% BUT I have neither heard nor seen any independent proof of it so am holding off for now.

They also do a air filter pad that is meant to help it but am even more dubious about that one, go for a pipercross or K&N

I've posted on this a few times in the past. In the case of the P38, Rewmer is 100% correct. All it will do is restrict the airflow.

The theory behind the Hiclone was to introduce swirl into the combustion chamber. All very noble in an engine from the 60's and 70's with a simple inlet but the M51 engine in the P38 is the pinnacle of indirect injection small diesel engine design that has had a whole lot of thought put into its combustion process. The Hiclone will only get in the way of all this brilliant German engineering. Save up and buy a chip or an intercooler or save even more for the new head you will need if you try to wring every last hp or lb/ft out of your engine.

The reason I know this is that I bought one for my old 200tdi engined RRC for which I completed pretty thorough before and after road tests. Resullt: a significant enough improvement in off boost lugging power (where the extra swirl was having an effect) at the expense of top end power (where it was constricting airflow). My 30 to 70 time in fifth was an average 10seconds faster after fitting while my 0-60 was 1.5 seconds slower. For me personally I was more interested in low end torque in the RRC so I left it in and happily ignored the derision of all the snake oil accusers comforted by the proof of my road test data.

Now one look at the M51 intake plenum should be enough to tell you that any effect the hiclone might have is going to be lost by the time it reaches the end of the inlet tracts and as I said earlier the pre-combustion chamber has been designed to produce the swirl effects far far more effectively than the hiclone ever could. I'll say it one more time, IT WILL ONLY RESTRICT AIRFLOW!!

BTW if anyone does decide to buy a set for any older LR's or RRC's, don't, only buy a single one. The one before the turbo is just B*llsh*t to up the purchase price. I didn't realise where it was suppossed to go until I got the fitting instruction but any effect the one upstream of the turbo could possibly have is UPSTREAM of a turbine blade spinning at several 000's of revs, yeah thats going to have a lasting effect.

Hiclones don't work. But i have in stock the six magnet system. One fitted to each injector to smooth out molicular flow of fuel, to help it get through injector nozzles quicker. 300bhp 400lb feet of torque and if driven normally 60 mpg around town better on the motorway. Only £100.00 each, so a snip at £600.00 a set plus vat of course. Interested?

PS. Pictures of genuine fairies only £25.00 each plus vat. Nude an extra £10.00. Doing sex act on hedgehog, £15.00 Extra. When available.

May i add that swirl effect does work. But it is for the purpose of mixing fuel/air in a conventionally asperated engine. Devices of this sort are of little or no use on fuel injected motors.

I seem to recall Suzuki introduced swirl on their bike engines. "TSCC" was achieved if I remember well by doing something clever with piston crowns and head design or something. As for the swirl from a hiclone actually reaching the combustion chamber I think it fair to say it is less than likely. Oh look a flying pig!!

But I also seem to recall that there is quite a bit of science in getting the mixture flow in to a head just right because there is a need to balance laminar and turbulent flow if you want it to work at its' optimum so introducing too much turbulence on the basis of improving fuel/air mixing is potentially a bit misleading - or at least I think that's right:confused:

Back in the sixties a motorcycle tuner called Francis Beart had an happy accident when one of his mechanics fitted a slightly under sized gasket to the carb of a Manx Norton. Before that all inlet tracts were polished and gas flowed to give as little resistance as possible to air flow. This happy accident caused a slight power increase. He also added length to the inlet tract, also encorporating his swirl device gasket and had considerable success with it until others cottoned on to his mods. These two mods incresed top end power and tractability as the engine came on the pipe a couple of hundred revs earlier. A great advantage in a race situation. But i see no advantage to swirl in the inlet side of a diesel engine as the air has been injested and compressed when injection takes place.
 
the 3.5 v8 has small toothed plate on inlet plenums , what I dislike is the hiclone is tested with no air box.
If it wasn't ****e then a no airbox, no hiclone test as a base
then hiclone and no airbox would show rolling road improvement if it wasn't ****e

Damn you Wammers, you are talking a lot of sense there!!;);)

There may be a bit more to it, here is an extract from Diesel Engine Management, by Bosch on the benefits of swirl, albeit ecu controlled. However that extract is for a DI engine and in the section on indirect injection it says that most of the whirl effect comes from the shape of the aptly named 'swirl chamber' as the piston compresses the ingested air.

Can't honestly see how the Hiclone can do much in any of these situations:eek:

But my road test figures don't lie!!

OP is obviously a spamming cuunt He does this on all the forums using a variety of user signin's. This topic has been done to death Hi conns are ****e and do fook all. but make ya wallet lighter

Yeah see that, swirl is generated by the shape and angle of inlet ports as the air is ingested. Then the fuel is injected in the opposite direction to the air swirl so that it mixes evenly. Liken it to making a cup of tea, if you make your tea let it stand to brew, then put you milk and sugar in and don't stir it. The milk sugar and tea will not mix until it is stirred. Then make another and stir it vigously before you add the milk and sugar. Then add it whilst the tea is still moving it will intermix. That is the principal. But to be honest i cannot see how a Hiclone would assist in that senario. As i said earlier the swirl principal does work, and did give good results in carb engines where the air/fuel is mixed before it enters the cylinder. But i would think that all modern diesel and fuel injected petrol engines have swirl built into them by design, so the Hiclone will not assist at all.
 
I think Wammers is taking the Mickey with his offer of magnets to fit the injectors: a little thought will show the orientation will have to change every time you turn a corner so as not to foght the earth`s own magnetic field.
Also i wouldn`t pay good money, or bad, for piccies of the bar-staff in that funny bar down town
Good piece on intakes on carb., petrol engines tho`. Also related to the reason golf balls have dimples. (to break down the boundry layer earlier and induce turbulent rather than laminar flow)etc.
