Why would you want a tornado?
There is a honeycomb screen at the intake. Its express purpose is to
"straighten" the air flow. "Laminar air flow" is what it is called. I am sure I
spelled that wrong, but anyway, the MAF relies on a small sample of air to
accurately guage the total flow through the much larger chamber. Swiriling the
air hurts - not helps this.
Perhaps the tornado would have some effect on a carburetted(sp?) motor, but I
would think the swirling there would throw the fuel against the intake runners
and slow down the air velocity - the very thing that helps charge the cylinder.
As I understand motors, a swirl in the combustion chamber could be good, but
anywhere upstream from that is bad.
