The plane- RV-9A, O-320, built to plans no cowl mods.
Used 2 tubes with muffs, 1fwd of baffle top center. 1 aft of baffle between the mags.
This was my first run so it is a little crude, a bumpy ride didn't help.
Next run I will tee into the static line to avoid this error.
Why? My plane doesn't have any engine temp problems
, just have it in my head that I want to fool with some vortex gens. on the bottom of the cowl.
Any one know the best angle for VG's?
Reading diff press.
