Ooooooh! I Can Get a Supersharger for My Discovery!
Tommo:
so why do they reccomend it for N/A vehicles as well????

The hiclone may increase the velocity of the air by inducing a spin, that'll increase the dynamic pressure. But this stupid thing actually spins, therefore it will take out energy from the air, to make it spin. A divergent duct, the air velocity will decrease (DVD-Divergent, Velocity, Decrease). Meaning this will actually slow down and restrict air flow!!!
Hiclone may help in turbo and non turbo, but this will hinder in turbo and non turbo!!!

HiClones work by introducing a lot of turbulence into the air flow. This acheives 2 things, firstly turbulent air flow causes less drag than laminar flow, that's why cars have spoilers ;)
Secondly it increase the amount of swirl in the air as it enters the combustion chamber, swirl helps with the mix but also helps the flame front to propegate across the cylinder.
From that point of view the closer it is to the inlet valves the better. Perhaps that's why you get 2 :-k

So my roof rack creating turbulent air is actually reducing drag??????
