Gurney flap on new beetle?

[bandit86]

How big should it be how high, and really what would be the best shape? I used to have a 1985 Toyota Supra I did had a great big one at the top of the hatch I almost think it might need to be that big

Gurney flap (wickerbill) is small, then you get spoilers and then wings. Each function differently.

The turbo New Beetle had an active spoiler built into the top of the hatch. A wickerbill would be appropriate on it's trailing edge. It's kind of a spoiler on the spoiler.

A wing creates downforce, while a spoiler is basically a vortex generator.

Julian [banned] Edgar made a similar wing with transparent side plates, but he only has four other threads remaining so it must have been in some other thread. It might be in his Autospeed pages.

What happened with Julian?

He got crosswise with the mods. Ask aerohead, I forget the details.
