Per Hucho et al, that vent would work best if moved forward about a foot. Air incoming at the highest pressure stagnation point on the nose, then drawn out at the lowest pressure point right about at the leading edge of the hood.
This will also draw off that pesky under-hood hot air, keeping the intake manifold cooler, for better performance.
My Porsche 944 Turbo is similarly shaped, and its turbo intercooler is under a header panel between the pop-up headlights, so I plan such a vent to extract air in similar fashion.
