Biplane wing?

[stockman1]

Has anyone seen any data regarding effectiveness of the biplane wing and spoiler on the SVO?

kind of like the hood scoop ..............really starts working over 100MPH.

My bi-wing was loose and has some homemade supports (somewhat functional). I removed the upper wing section leaving the trunk lid spoiler in place. Thinking of going with this because; I like the look, can see out the back better, I can put it back on in just a few minutes. Need to fab something to fill in the gap left at the head of the spoiler and maybe rubber plug the screw holes. Or not.

Just get a 87 up spoiler and you wont have to do any filling. They are cheep around here.
