I got lucky in way. There were some guys on the Innovate Motorsports forum who really knew their stuff. My learning curve was a bit steep but eventually the brain cells started connecting. There were a couple reasons I knew these guys knew there stuff. One, they were having intelligent discussions with the owner/inventor. Two, they didn't know it all but had approaches to solving problems, and had questions about how things worked . Three, when they referenced stuff, it was NACA, SAE and real science and engineering literature. Damn! Four, one of them (screen name Tuner) had helped a couple people I knew their road race cars. I respect his wish to remain anonymous on the web, but it was fun putting the clues together.
