I would imagine that if someone finds a way to remove air from the rear of 
the fuselage, whether through reverse NACA vents under the stabilators=C2
-or if Bud can figure out a way of removing air through the flap vents, t
hen standoffs under the =9CD=9D panel could help draw air out o
f the cabin.Now a drawback would be if the pressure drop inside the cabin m
ight start bringing in more exhaust fumes on the mono?Does=C2-anybody hav
e any concern of=C2-any structural issues with a flap-style vent=C2-on 
top behind=C2-the doors?

Hello all,

I appreciate the discussion this thread had yielded.=C2- So, in my case I
 have a ram air NACA duct in the lower cowl which provides more than suffic
ient airflow to the two eyeball vents located in the lower portion of the c
enter instrument panel.=C2- The challenge I have, as previously mentioned
, is getting the air to exit the cockpit in order to relieve the pressure w
hich causes excessive bowing of the door frames.=C2- Unfortunately, the s
tandoffs on the D panel aren=99t sufficient on their own, and I curre
ntly have just the pax door seal on at the moment.=C2- 

If I understand the latest analysis by Area-51 an exit near the horizontal 
stabilator may do the trick.=C2- This may also require longer standoffs o
n my D panel if that becomes the flow constraint.=C2- 

I am also interested in hearing from Pete who has a reverse NACA installed 
just aft of the doors on the top of the canopy.=C2- Noise and weather con
cerns notwithstanding, does this solution get the job done?

Thanks everyone for providing their time and energy to this question.
