Carbon fiber NACA duct- 4 inch tube
The Tonka NACA is complete! I love it when a plan comes together... In my opinion it came out really nice and everything went together smooth. Very adjustable as far as angle of the tube goes. This first one I set at about 45 degrees more less. If anyone is interested in it please email directly to me. It will be a little while before it goes up on the web site.

4", as in sized for an oil cooler eh? Hmmm. I'd love to know dynamic pressure values in comparison to a pitot inlet, i.e. a conventional engine upper plenum. If equal, this approach to feeding an oil cooler would be superior. As reported elsewhere, the air picks up a lot of heat in its pass through the plenum on the way to oil cooler.

Might need to make an oil cooler plenum now. I'm going to see what my oil temps are this summer.

Do you have a scoop that will fit a 3" SCAT tube? I'm VERY interested....
