NACA vent location?

[N634JT]

I am getting ready to make cuts for the rear NACA vents (Vans SV1) that will feed the Aerosport overhead console.

It seems that most have placed the vents forward, just behind the baggage bulkhead, in the panel just below the longeron. I am aware that there has been a fair amount of discussion about this placement, and it's proximity to the static ports. Everything I can find, indicates no problem.

Before I make "the cut", I am looking for feedback confirming no ill effects on the static system.

I also saw a reference to a paper template. Any idea where I can get one, or is this a DIY item?

Thanks,

M. Tippin

NACA

Trace out one of front cutouts on paper..laminate....cut out and you have a reusable template...as for placement, I went with Geoff Combs advice as he is the expert!

There is no "correct" location.

Most put them on the panel just below the longeron and center between the two vertical rows of rivets. Mine are a little forward than where Geoff located his. Since the naca vents usually produces more air than you need, I don't think location is critical. The reason I put mine a little more forward, was due to how I chose to route the scat tubing to the Aerosport Products naca vent and then on to the fittings on the bulkhead.

Agree - as long as it's facing the right direction and level, you are good to go. That first panel is a good spot and most use it.

Here is mine

Don't know if this is the "correct" location but it definitely works very well right there.
The Aerosport controller is also very helpful during colder times of the year.
No problem with the static ports either.

Mine are located immediately behind the baggage bulkhead as shown in Ernst's photos above. I am using the Safeair1 static ports, and I have no static error whatsoever.

Me too. No static port error that I can detect.

I also used some of this screen door material (http://www.homedepot.com/h_d1/N-5yc...&keyword=screen+door+fabric+pet&storeId=10051) cut into 3"x3" squares and places over the inside of the naca vent when I attached my SCAT tubes. Keeps the critters out, this material is a polyester material and wont rust either.

I did the same thing. Didn't like the idea of fighting a bumblebee in the cockpit on short final.

I used maroon scotchbrite cut in a circle, it didn't seem to cut the air flow
