Well you haven't mentioned anything about tufting but I can't imagine any
tunnel work without it. Bring a big ball of black yarn. Since you are a
pilot you know the drill.
An excellent comment was mentioned earlier on the list about a "static"
scoop test. I would think tufting all around the scoop would be extremely
valuable, but especially right near the front entrance. I can't tell how you
how to make the test "dynamic", but maybe hooking up a weed blower or
sumptin (inside) for suction, with a way to modulate the CFM to simulate
your max motor CFM, would be desirable. Tufting may effect laminar flow so
the tunnel scales might be off on a tufting run. However, the visual
education would still make it a valuable run. Since you want to experiment
with deflecting the air stream over the roll cage, (i.e., test no. 3)
tufting the top of the bars will tell you a lot. Looks like a great plan,
good preparation, and lots of fun. Best of luck and good data, -Elon

(snip. . . ) 10 tests possible without rushing... so here's my plan to use
them.
3. Windscreen tests
4. Roll bar covering
5. Old Hood scoop with new tail section.
