Me and my friend were chatting recently and he suddenly brought up the topic lift hood.
I remember some guys who lifted their hood slightly higher at the part near the front wind shield told me that it is a method to let the hot air in the engine bay escape.
But according to my friend, by lifting the hood up, when you are traveling at higher speed, the air traveling above the bonnet is faster than the air traveling inside the engine bay therefore it generates lift which reduces the downforce of you car and also creates a vacuum in the engine bay resulting even hotter engine bay and reduced front down force.
Anyone got any idea about this?
His theory is, air got no restriction while traveling above the hood coz got nothing to block it, air that goes in from the from radiator vent will have alot of restriction due to the parts in the engine bay.
Is his theory correct or wrong? I would think it is correct but how bout other sifus?
