If you want to maintain yours cars performance the track, heat is not your friend on any high performance engine so the primary reason for hood vents is to get the heat out of the engine bay so that the engine can work efficiently. Getting the hot air out is not the end all as in doing so it should not impact the performance of the cars aerodynamics. If fact the air flow should be used to create additional down force and therefore aiding in the overall performance of the car.

Now that you have been edge-mi-cated to the basics, you are oblige to if you can not provide any useful commentary!
