I'm progressing on getting it ready to paint and one item that I need to finish is the "tonneau cover" over the passenger seat area. I decided to add these two NACA ducts that I have been carrying around with me for 15 years. They are fiberglass and will mold into the cover real easy. I don't know if they will really do anything but they may suck some air down into the engine. I'll tape some 3" hoses to them and stick the discharge end into the cooling fan.
I have to change the cover because I changed the roll bar supports. I used to have a big bar going to the top of the main hoop but that was changed and lowered to the center. This required the cover to be changed. It now can be molded to match the left side radius and I'm adding a 3/8" edge flange for strength. I'm kinda going for the 908-3 look. Attached thumbnail(s) |

Looking good, Paul. If you find that the NACA scoops aren't drawing in enough air you might want to try adding a few vortex generators in front of each inlet.

(IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) PS, I learned that from the raised roof thread this morning and the link to vortex generators. Good info, not that I understand it all. (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) But now I know why the Chaparral 2H had vortex generators in front of its air intakes. Cool.
