We actually had this discussion over on the s2ki forums. Someone drew up an autocad design showing the airflow over the vents. Now I'm no expert but this was how it was explained to me. The airflow over the vents would be considered negative pressure. So unless you had some sort of scoop say ala STi or a dip on the hood itself, the vents wont be as efficient in dissipating heat at higher speeds. Again this was how it was explained to me. I hope you're right in this instance

the second picture looks like a decal laying on the hood because of the glare...are there any closeups?

i would like to have this in conjuncion with ram air cut outs in the bumper on both sides...

those are some seriously clean cuts bro! looks factory

did you have to have the hood repainted or did you just blend in the areas around the vents?

kdo2milger · 09-09-2009, 11:45 AM

these vents plus 2 ram air holes in the bumper directly infront of the intakes = gravy

with a side effect of cooler temps and fresh air intake

so when you cut threw the aluminum hood, what did you use to cover the unpainted surfaces?

did i miss the DIY thread on this or is it still being put together?

i am really interested in doing something along the same lines as this...
