Hood Extractor for Downforce

[truegearhead]

I watched a little too much 24 Hours of Daytona this weekend and ended up cutting up my old stock hood (and inside my trunk..yikes). I don't have my splitter installed in these pictures but the idea is to increase front end down force. I have a wing installed on the rear (not at the moment) so I'm trying to balance it out a bit. ITs just roughed in at the moment, any advice? I still need to create the ducting for the trunk.
