For anyone who has used the Naca duct on the rocker, how did you route back behind it?

I was often thinking that when I restore my car I wanted to get rid of the jack posts completely on both sides. Put Naca ducts in the rocker panels where those would be. Cut a large enough hole in the long (where the jack post plate used to be) and connect to the tubes (normally used for heat). Either route those up to the engine bay for fresh air intake or point them at the trans or external oil cooler.

Then just put in electric heat. Simple. Just kidding about electric heat. Maybe heated seats though.

Here is my solution. NACA duct cut into rocker panel with hose connection routed to auxiliary oil cooler. No problems with dust or water. Subtle and powerful. The NACA duct is very efficient to suck in air.[ Keeps oil at 210 degrees even on hottest days. In the colder months I close up the duct. attachmentid=475909]

I posted pic that shows the hose routed to an auxiliary oil cooler that is shrouded to maximize air flow across the oil cooler. To get the space needed, I used Tangerine Racing street exhaust system which gives more room on the passenger side for the oil cooler to be mounted in a near vertical position.Click to view attachment

I did this for my rear cooler too. Check post #43 for route pictures. That's three inch duct work. I moved my oil cooler to the front of my car. May keep this for a trans cooler, not sure yet.

Just go through the Sail Panel

Sure,with side mount rads,intercoolers,you would need inlets/scoops/ducts.

Apples and oranges here since my car is not a Porsche body, but these are the NACA ducts on my car.



I'm no mechanical engineer nor did I ever take a physics class. . . With that said, the NACA ducts on the Squarsche work better than I had anticipated.

Before the latest revamp of the car with stock cooling, I would see a spike in head temps above 60mph (400F and climbing). Once I added the NACA ducts, head temps usually sit at or below 350F (have never gone over 375F) and above 70mph, the engine runs cooler 290-325F (even with the higher engine speeds and higher load).

NACA ducts not only work well, but in my experience they become more efficient with speed and just work better and better by design.

I can only imagine her "scoop."

NACA vents aren't air scoops per say rather inlets. They are to be placed in high pressure areas for max efficiency. The faster the air movement about them the better they work. Any AE's here that have done any wind testing on these birds?
