Functional hood scoop on stock GT hood
I have an 02 GT with the stock gt hood. I was thinking about cutting a hole in the hood to make the scoop funtional, although it would only provide fresh air over the entire engine and not directly to the air intake like the shaker hood scoop system. Is this a bad idea?

I heard stories abt them flying off, so I took out the honeycomb piece in the hood scoop and drilled through each of the honeycomb holes. It was a PITA but the honeycomb piece still gives it some structure while helping the engine cool a bit. It helps down here in TX on the hot summer days.
Sometimes I can see the heat escaping from the scoop at a stoplight.

I've posted this a few times before:
Don't do it. The underhood airflow characteristics are very important to cooling performance, and cutting a massive hole in the top of your hood and shoving differing amounts of air through it at different times is a bad idea. Furthermore, when it rains you'll be pulling in lots of water that will land on your very hot engine. Hot metal + cold water = stress and strain.
I actually had something similar to this done on my mustang by the previous owner. There was a chute leading from the scoop to my airbox, and a hole cut in the side of the airbox. The opening to the scoop and the hole where actuated by the engine vacuum. When the vacuum was positive, the scoop was closed off and the airbox simply inducted air from the engine compartment. This was great because it made the restriction on the intake air less, as well as shielded the car against rainwater entering into the intake stream.
However, once the vacuum was reduced to zero (at WOT), then the hole was closed and the scoop was opened. Thus, the movement of the car forced a slightly larger amount of air into the engine at high RPMs.
It was a pretty cool design, but entirely pointless. At best, it just looked kind of neat and was a good conversation starter.
Again, I would highly advise you to not do it. You'll be screwing with the airflow under the hood, which is not something you want to do.

You would need a shaker hood and setup if you want to make it "functional". Blowing air onto the engine is not going to do much except cause trouble. A cowl hood will cool things down way more because it will suck out air instead of blowing. I've heard of a few DIY hood scoops blowing off at speed. There will be a TON of force on it at 100mph.
