The web page for the Tornado shows it before the carb. With the Bing this would
probably be a big problem as the Bing likes a smooth air flow. The TBI 40 may
tolerate it but putting something like this after the carb would seem to be much
more desirable. In the 3300 design, there is very little room to do this but
that is what I am working on.
Of course, the Tornado claim of doing anything with today's electronic fuel injected
auto engines seems unlikely. All the fuel mixing takes place right at the
intake valve.
The Tornado claims to fit in airways between 2.5 and 3.75 inch dia. The outlet
side of the carb is about 1.6 inch dia. It might still be useful to start with
this thing and modify it to fit.
One thing I did find is that simply making the air rotate does not help, it rotates
some very lean air into cylinder 6 although it helps with the others.
It would be really nice if the manufacturer (Rotac or Jabiru) would do this right
and design the required coupling on a test stand.

Mark,
Thanks for the pictures. It is very helpful to see your fabrication. Lucky for
me I have no interest in dual throttle cables. The extra friction looks like
a big negative.

Mark,
I'm pretty sure Mark Langford placed his Tornado downstream of his Ellison TBI.
