I've replaced the center section of my Exige 2010+ style wing with a carbon blade, mainly for looks and so that it'll stop bouncing around in my rearview.
Which left me with the original blade sitting in corner, and I started to look at it and say, could I use this spare blade as a track version. Something that's likely ugly but functional at producing additional downforce.
There's a bersion of the Exige 2010 style wing sold by one of the vendors that produces more downforce by changing the AOA of the blade. I don't have those uprights, but if that's functional, it means changing the AOA of that blade will increase downforce.
I also know that Gurney flaps primary method of increasing downforce is essentially changing the effective Angle of Attack (AOA) usually at the cost of drag, but I'm not super worried about the drag with the supercharger.
So I was looking at cheap universal gurney flaps, and you can visualize how these might change the effective angle of the wing and produce downforce and drag:
Anyone have experience with this type of stuff before I start buying ebay junk and riveting it on to my old blade and doing some old school string wind tunnel testing.
If you're not familiar with the string method, see video:
Once I got a shape that looked promising I'd probably skin the whole thing in fiberglass and finish it a bit more. Would be heavy and ugly but I'm looking for effective cheap and easy to install/remove.
