The bottom of the window is a high pressure area.
The flow is actually into the engine bay when driving.
A low pressure area is usually at the front of the bonnet, which will pull air out the engine bay.
Hence why scoobies have vents at the front and scoops at the rear.

Aerodynamics have improved since then; the New CLK (with delusions of grandeur) has a Cx of 0.24. Which is pretty impressive flow management.

In about 1969! Lean-forward noses caused all kinds of lift & vortices. But a fairing over the wipers was being used to calm the pressure wave over the base of the windscreen. (Origin; Rover 1963)
Hence the fact you get airflow into the car through the vents when travelling at reasonable speed with the fan turned off.

We used to washer up the bonnets on skyline and silvia drift cars. It also help with the air flow around the oil filter which was relocated to the front strut . I never thought of removing the rubber along the scuttle

How FREAKY
Well i removed the rubber strip many weeks ago, and did not make much of a difference, although people seem to think it does, did not notice any difference
but yesterday i decided to raise the hood. I placed 2 x washers on each bolt which hold the bonnet on and raised it enough but not to noticeable to the eye
so what do i think of that, i think it was a good idea, i could defo feel hot air coming from the new gap, when the fans kicked on where i could not before
i have also today been doing some getto cooling mods, from taking air from under car and directing it behind the intercooler and onto the oil cooler and aircon rad , this worked very well on the way home tonight after a very spirited drive

I will wait to see Phil's bonnet before going down that route but minimal lift should be barely noticeable.

Who was the guy at Euromeet that put in some holes in the wings
Looked not bad - in fact... it didn't even look chavvy.

From memory it was a Seibon wing, but I could be wrong.

I have removed the rubber strip on the scuttle after chatting to Lloyd about getting the hot air out of the engine bay.
As for the Mazda...it does work, having seen it first hand a number of times...looks a bit naff though.
