Here is something a little more interesting. I dont know about you guys, but my car has very little airflow inside the cabin when on track. It gets VERY hot, a lot worse than most cars.
I decided to re-purpose the rear window as a drivers air vent. These rear windows are insanely glued on. It was VERY hard to remove, and yes when I was 90% done the window shattered into a billion pieces. Just go ahead and smash it from the start. Waste of time.
Ne ways. Glued down some Plexiglas cut to shape, plexi naca duct glued on top of that. It looked pretty messy once all the glue dried up with the few layers. So I plasti dipped over everything nice and thick.
My buddy 3D printed an air guide for the end of the hose. I also used super strong magnets from amazon to hold the scoop to the seat fabric. One on each side. Its stuck on pretty good, and easy to adjust with on hand.
That Z has come a long way... I see my Z ending up going the same direction. Every day I find my self more and more tempted to just make it a full blown track car.
Did you use the NACA duct only to feed air towards the driver?
What about air exiting the cabin?
That is the problem with our car. The rear flapper vents are small (compare to a e46 m3).
Air into cabin= air out of cabin in our scenario. Once the intake overwhelms the exhaust (rear cabin flapper vents) no increased flow will happen.
There is a good chance that naca duct/vent/tube will not push much air at you as your windows has already overwhelmed the vents(ive tried as well).
The solution I am using is a few more flapper vents in the rear. No more heat sickness for me!

I did drill holes from the rear trunk into the bumper area last year, didnt help much. Thanks for the tip on the flappers. Why not just remove them?
Interesting, I noticed quite a difference!
Well, if you didnt notice more flow with more vents in the rear I doubt flappers would make a difference in that regard. What was your vent sizes you cut?
The flappers are more for lower speed situations (yellow flags) where you dont want exhaust in the cabin.
2017 is here! First event is in the books. Back to Lightning with Track time 4 cars. We got OVER 120 laps! That's 12 sessions. Light turnout, made for some good fun.
KILLED the brand new pads! Maybe have a short event left on them. Will take it apart and see.
It was COLD but dry all day. Matched my best time 1.18.9.
