    [Image] Hi Patrick I only fitted this last night. It took a lot of deliberation!! The position is quite limited once you sit in and consider where your legs go. I'm hoping to get the port side fitted tonight........... fingers crossed.

    Hello everyone, I've been following the vent discussion and I wanted to share my approach to this. 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. Paul

    Subject: NACA Vent profile
    Hi Everyone, There was some discussion regarding NACA inlets during the "Vent" discussion. 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. Paul

    Bud: I may have missed it but did you address wind noise ? 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
