With my VERY low level physics knowledge, I would expect the air to come out of the hood since the air flowing over the hood will be at higher speed than the air in the engine bay. Faster air = lower pressure, therefore the air from inside the hood will try to equalize pressure and come out of the hood.

Personally I love all the "string to check airflow" arguments on this forum lately. 1 - Hustler gets to bash people. 2- It's friggin free and takes so little effort to do why argue about it!
Just try it. If the ribbon/yarn/string sucks into the engine bay it's not working. If it is blowing out, guess what! It's a pretty good chance the vent works. If you want to know exactly how well it works you gotta get more technical with pressure gauges and thermometers to check the cooling effects.
Not trying the ribbon 1st is like draining your oil to see how much is in the crankcase instead of just looking at the dipstick. For just about anything in life - always try the easy free method 1st. If that's inconclusive then move on to more technical methods.

I like it 
Would've been cleaner with countersunk rivets or even better with epoxy (no rivets)
Do you have any problems with the windshield fogging up on muggy days?

ah yeah, countersunk rivets would've been cool ^_^ I don't know how well epoxy would stand up to the heat from the sun as well as the turbo.
So I'm happy to report that even without a heatshield, I didn't have any brake fade from boiling the fluid in the proportioning valve. This is even after almost 2 hours of driving on the freeway, autocrossing, and then driving home. I just need to finish up my radiator scoop and then I can stop worrying about overheating =)
