Aerodynamics of a bug

[judgie]

your'll be sirprised how many race cars run with plywood splitters and floors. even F1 run a ply floor as its a very good metrial for the use. its very impact resistant, its light wieght and it wont shatter. perfect qualitys for some thing thats going to get bounced over kerbs.
i have even seen plywood spliters with a layer of kevlar over them to give even better abrasion resistance.

I know someone who stage rallies with a plywood/polycarbonate sump guard that is impressively strong ....and light.

A picture I have made many years ago of Bernd Rummenholl's 1303 Gelb-schwarzem Renner, which had the top of the front bumper towards body closed off.
This is something I will finally realize this winter, plus I will add a little twist to it myself

Hi Wally

I had a similar air dam on my old 1302 in the 70s & 80s.

Well, I thought don't talk about it, lets just do it!

That special projects page is what i'm following to make my front splitter. Having talked to a few ustcc teams and fabricators that splitter design is almost a standard.

I've considered a rear diffuser and using naca ducts to pull air from the engine bay but I'm not sure how well it would flow.

Wally, i would put the side piece even higher and blend it with the contour where the wing meets the extension.
You will also need to close the /extension - side piece - bumper - splitter/ area and also extend the widened wing downwards to the splitter

pretty much you will end up with something looking like the Jsports front bumper...

or you can get the side piece merged with the contour of the extension/wing line, trim the bumper edge towards the centre of the car and project the wing extension until it meets the splitter...

I hope it makes sense

otherwise give me a side view and front view pics of your beetle centered on the area for me to draw it for you...
