Since I mentioned the fact that I used to collect aero literature , I wanted to mention one particular magazine I bought that is now long gone
(. I threw away all my magazines and pictures, convinced that my hobby was to nutso. I used to even go to dealerships to get the sales brochures for the Cd figures on the cars )
This particular magazine was some custom car magazine from the late seventies to very early eighties .
Besides the usual Mopars and Chevy Camaros painted in a maze pattern flake paint jobs using 20 different stripes of paint, there was an article that had me totally enamored.
The author had taken a '69 Camaro and performed several aero tests on the car.
Tests consisted of coast down testing, tuft testing and pressure testing using an instrument I have not seen mentioned here before.
It was a small funnel attached to a piece of clear tubing , and the placed at the cowl area of the windshield . A solution of ink was inserted in the tube and as the car gig up to speed, the funnel would blow out the ink in the area being tested for pressure patterns.
I really do miss that magazine. I think that guy would have been one of the first true aeromodders !
