Bonnet scoop

[petrolh34d]

Because it's positioned directly above the turbo and exhaust manifold, a lot of heat gets conducted into the inlet manifold.

After driving the car for a while, the inlet manifold is pretty hot to the touch, which would would surely negate all the cooling that the intercooler has just done?

I'm toying with different ideas for trying to prevent this including, heat wrap, carbon heat shield, and naca bonnet vents and louvres.

Would it be effective to set up some sort of venting system whereby air is taken in through the front of the bonnet, ducted past the inlet manifold, and then use louvres at the rear of the bonnet to exhaust the heat?

I'm open to suggestions and alternatives.

Here's a very rough, and incredibly not to scale diagram of what I'm proposing.
