I am thinking about doing this.
They would be small so it doesn't look like a rice racer, I like the idea of getting fresh air into the engine bay. who's done this?? got any pics?? |

Not mine but you might be able to see the huge scoop on the right rear fender.

that's a radical teener! I'm thinking along those lines, in the same location but smaller.

Those would be "NACA" ducts. NACA (National Advisory Council on Aeronautics) being the predecessor to NASA.
Another air intake on the rear fender: http://members.rennlist.com/bluethunder/ I've seen pics of one with a 1st-gen MR-2 scoop in one or both sides, as well. All that only looked "OK" to me.... --DD |

Hope you plan something a little cleaner and more integrated than this car.
Apologies if it's someone here. Attached image(s) |

Consider a scoop from the engine lid up to the roof, Your'd only need to modify the engine lid, not the body, if that is important to you. i have seen some like that, they look ok!

Dave,
Thanks for the correction! I've been in 'wine country' way too long.... Greg Those would be "NACA" ducts. NACA (National Advisory Council on Aeronautics) being the predecessor to NASA.

I like the size of the air intakes on the yellow car. It looks like it can be covered by a small fairing and the overall apperance would be subtle. I don't wan't the rice racer bolt on acessary package. Functionality is what I am after.
Are these avail. for purchase or is it a one off, design as you go type thing?? I am thinking of an oil cooler on the pass. side, inside the fender well and a fresh air intake for both the motor and the engine compartment on the other. |

now this one is mine (IMG:style_emoticons/default/smile.gif) a simple naca duct bonded into the fibreglass flares.
Connects to a 3" pipe that runs into a modified 911 intake chamber. Attached image(s) |

Do you have to worry about rain with those scoops?

Just out of curiousity how much air do the naca ducts actual suck in? I think you have to have pretty smooth airflow over the surface for NACA ducts to work well. Supposedly they allow air intake with much less drag than a scoop located in the airstream. On NASCAR stock cars I always wonder how well the three NACA ducts work located in the rear side window behind the open drivers window. I know the NASCAR guys use plenty of wind tunnel time, but it looks like the airflow after the drivers window would be turbulent. I think these feed brakes and oil coolers and they probably have fans attached as well, so the flow must be adequate. |

This is a very nice job by WRTHBEGO I think. They are fully functional and look like they belong.

It was hard to get a visual of how it would look on a street car. The version on the red car is not too bad either, other that the bolt on look. Has anyone ever used the center tunnel as a duct?? With a little creative plumbing it might work |

With a little creative plumbing it might work If the red car you're talking about is mine I'm planning on working it into the body so it doesn't look quite so bolt on. I just have to figure out how to do that (and I also have to fins the things, I lost them when I took them off at the beginning of my restoration (IMG:style_emoticons/default/smile.gif) ) |
