Bonnet Vents

I've been planning some bonnet vents on my new bonnet.

Having read up a bit, i wanted to get more air in, but also let hot air out. Also thought i'd stick a few vents in the side near the inlet to get a little extra cooling air there.

Any comment welcome, any suggestions before i cut them out?

Thanks

I seem to remember reading that simple slots in a panel doesn't flow as much air as you might expect. The NACA duct is the best way to get air into (or out of) a car.

Yeah i'm aware that "ducted" vent would be better, but i dont really want to go to the hassle of fitting it painting etc.
