Re: Aerodynamic improve ments
First off goat, never to trust a site thats trying to sell you something... period.
Second- You ask for help, then when you get it, you tell the people they are wrong...
Third- "Vaccum Effect"? You mean drag? A VG is used to decrease drag, not provide downforce. The only thing a VG could be considered to help is the reducing the boundary area which may at the slightest level (I'm talking .0000001%) exchange some parasitic drag for lift induced drag. But its main function is to elminate drag, not provide downforce. Putting a VG at an sharp edge is almost worthless.
"If you add downforce to the rear you MUST add it to the front....vice versa" --- False, or what, your car will spontaneously explode?
The reason for the Fiero's high drag co-efficient is its sharp (almost 90 degree's) after the roofline. This creates a low pressure area-- aka drag-- (this is also why those vents are designed to let heat out, not push air in) perhaps this is what you meant by vaccum effect?
You want to reduce drag and get some more down force on the fiero? Make a smooth, rounded panel that covers the rear decklid that extends to both pillars, roofline, and rear of the trunk. Only then would a VG be useful on the car.
You need to take a course in fluid dynamics, ...
And if you think I'm talking out of my ass, I invite you to critisize me. I've worked at NASA Langley wind tunnel for over 2 years and would like to hear what you have to say.
