Hi Tae,
I had a look at the "Iceman" air intake and my results are:
If you have a greater diameter of your air intake the exerted force
(because of the pressure) will also be greater - and probably Iceman is
right if they claim the shape of a "velocity tube". They are most
definitely right with respect to laminary flows, I am not so sure in case
of turbulent flows. The only thing you can do is an experiment - and if you
have a look at the
picture on Iceman's web-page
they showed the advance of their air intake. As I said, as long as you have
a shape where you have laminary flows, that's the important point -
unfortunately I am not an expert in this field, but probably they
calculated the shape they are using so that should be the case. The effect
that the air gets hotter should be negligible, simply because the diameter
is 50 percent bigger, means that the area is twice as large - so a few
degrees should not play a role.
So, the answer should be: Iceman provides a bigger volume of air in the
same time, although a few degrees hotter - in the end I think Iceman is the
better (at least: more powerful) choice.
I hope that answered your
question!
Bye,
Andreas
