Don't worry I'm too stupid to know the specifics even if I were told them.
We're (my team and I) working on the brake cooling system. Basically they have two inlets at the front of the car that direct air over the rotors and calipers. What we are doing is testing different configurations that they use in races to see which are optimal for what kind of races (short track, medium tracks, etc...). For now we are using a flow car to push air through a full scale system and measuring pressure drops. We have to have a website up by december if you want I'll throw a link on the board when it's done.
