New Cheap Aluminum wing option
#65
Results are available - Nine Lives Racing: The "Big ****" test
Not knocking 9LR, I would have picked up one of these myself if I had not completed building my own wing literally a week before these were announced. But I still want to see real CFD/wind tunnel testing for numbers and lift/drag, not skewed tests vs a 3D wing before I sing their praises.

I wave, every single time.

Those are pretty impressive numbers and look like they could be improved considering the lack of a gurney. Can't help but notice this was on a 70" wing, not the 64"/68" that are legal for most miatas in various classes. Still 200lb of downforce @100mph with only 20lb of drag sounds pretty dam noticeable.

Also, yes 9LR's CFD is on a 70" wing, but APR does not list the size they tested the GT-250 with. Since the largest size they offer is a 71", I'd assume that APR's numbers are based off of their biggest ****.
73lbs at 60MPH and 10° without a flap sounds pretty decent too...

1-3% of chord length according to https://www.sciencedirect.com/science/article/pii/S136988699800010X
Nlr states ~9.5" chord length ergo 0.095-.285" for the flap length. The channel embedded in the wing is about 0.285" already.
Maybe find some aluminum or carbon fiber angle stock to fit?
I measured the width of the channel at 0.086" so that's the approximate limit to how thick the gurney can be to utilize that spot.

It looks like it's designed with something specific in mind which was why I was asking. Using some 90 degree aluminium angle stock it looks like your gurney flap will stick at an odd angle. Could just be the picture that looks like though I guess...
