vendor help would help me the most but if any individuals have had a windtunnel test performed on the following products that would be helpfull. downforce firgures aswell.

voltex GT wing.

APR GTC-300 wing.

 

Can't help you on these two wings, but the guys who helped out with aero for our PPIHC car, DHP Composites, had some downforce figures, though not sure if they were computer derived figures or from wind tunnel testing. I may be talking with David in the next couple of weeks about developing a multi-element tuneable wing for next year.

how can I get in touch with DHP composites? I'm interested in their stuff but can find little info on them. Any help would be great!

 

Sending you a PM with his contact info.

I'll see if I can find anything on the APR wing, I saw something not too long ago.

Main thing is you need to get the wing height perfect and also the angle of attack. Wind tunnel tests are great you just need to make sure you can reproduce the exact settings used.
