New Hood Mod! NACA Ducts!

[Chopper]

I think, maybe, save the costs of ducting... let them be extractors. The location is too far back from the airstream to realize any ram effect and is actually in a low (negative) pressure zone. Notice rams are located at the vehicles leading edge (hood lip or grill in GM cars) a high pressure zone, or near the windscreen base (another high pressure area) Cobras, Subaru, and several GM designs. Think about the huge hole, right in that spot, on an Evo... it's all about getting heat out. They even designed in a little" kick"around the hole to lift the air even more, creating more "suck" I think the piping won't help anything,and if made tight,may hurt. IMO love,Wayne

My inspiration for the ducts actually came from the Porsche
924 Turbo
968 Turbo S
928 GT - Custom

Even if they don't work quite the way they are supposed to, I'm happy that they look cool and provide even a LITTLE bit of extra cooling during the Nevada summer

Looks nice Bullet...Hats Off ! ! !

He could always just supercharge that would make the air flow more of a direct feed to the intake, or better yet let me test the hood out on mine.

The scoop offers little airflow, so even cooling is minimal. The slope of the hood appears to raise airflow over the scoop more than in. Sometime back I taped some ribbons around the hood and near the scoop. All airflow is more to the front of the hood, so the scoop would need to be positioned more at the very front of the insert. There is SOME airflow at the scoop location, but I dont think it would be enough to utilize as a proper ram air. I went through this way back when, when I decided to try a ram air mod, but it simply wasnt enough to work with. We suffer the same issues that the STi hoods suffered pre- '06. The scoops were enlarged for more air to be scooped in to the TMIC. I am thinking that a pre- '06 STi hood scoop size on the VX would look insanely silly.

Our best bet for good ram air is through the grill or better yet, mod through the round parking lights in the front cladding.

You might want to pop your hood once a day to make sure the mailman didnt stick any mail in there. Might start a fire under the hood.
