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
