Designing better APR GTC200 Endplates
#11
Even if it just results in a 2% reduction in drag, I will consider it a a success. I will come out of the project more knowledgeable than I am going in, which is my main goal. Being a 3D wing, these have quite a fair bit of drag, so I think there is something to be gained here.
I also work in the industry (aerospace design) and have always wanted to tailor my knowledge to the car. I've done my own airfoil designs with actual wind tunnel testing, so I know even small changes can have big outcome.
Even a failed test is successful

As for the split scimitar...I know that wing width etc has limits based on classes, and either way its always better to just have more wing than to have fancy winglets (think 787). Airplanes are limited by gate width limitations, race cars are limited by class rules. But I figured this was more of an experiment than anything, and the split scimitar designed correctly will probably yield the best results.

I have quite a few tools built up at this point! 2 3D printers, a homemade CNC/printer/laser etcher, now a 3D scanner I made from an Xbox 1 kinect. Google it, its pretty easy to make the scanner, the hardest part was sourcing a Kinect for me.

Calculated my downforce/drag numbers for the stock wing. They are both close to what APR mentions on the site so I am going to move forward with them.
When I get back from a track day this weekend I'm going to do my first run with a basic 12"x12" endplate.

thanks for the info about the Kinect. I didn't even think to look up a way to build one. I wonder if an xbox 360 Kinect would work. I have had one sitting in a box in my closet for years.

All you have to do is solder a power supply and buy a USB cable to connect to your PC.

These are another good option. I had to take a lot of angle out of my GT250 to match the balance of the car when I installed their endplates.
