It's far from simple but it works really well. I put a standard heat box on the firewall. On the instrument panel side I fabricated a plenum with 4 outlets. Two were used for the windshield vents and the other two feed some eyeball vents on the panel. The air feed on the firewall side comes from where I have my turbo charger intercooler air box so that is unique to my installation but finding a place to pull high pressure clean air shouldn't be difficult. Needless to say the result is really good but it is a far amount of work. I do have some photos somewhere and if there is enough interest I'll post them.

I needed some NACA's but I could not find them in the size I needed so I made mine. It's a bit time consuming but once you have made the templates you can make as many as you need. Unfortunately we generally only need a couple. I don't recall the source of the attached spreadsheet but it does a nice job of calculating the profile. From the profile I created two templates for the depth and two for the sides out of aluminum. I then used the templates to hot wire a foam core. Once I had cut the core I covered it with heat shrink plastic and used it as a plug for my layups. If you're lucky and the plug releases you end up with a perfectly smooth surface and you can re-use it to make the second one. I'm sorry that I don't have any pictures of the process. They seemed to have disappeared in the black hole called "hard drive" A few other comments. The inlet ramp needs to be blemish free and a smooth transition with no bumps. As others have mentioned they need to be correctly aligned with the airflow and a smooth transition on the outlet side to your hose. I have oil streaked mine and the airflow is correct.

I have always been concerned about "things" that project into high speed air. Paul: Yes please, on the offer of photos. -------- 46 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=501151#501151 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message europa-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Europa-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/europa-list Browse Digests http://www.matronics.com/digest/europa-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
