Airscoops and channels

I made the air-channels that have to guide the air from under the car into the radiator-airbox:

This looks simple to make, but it's more difficult than you think. I all runs at an angle, not only slightly to the back (so the angle isn't too steep), but also to the middle of the car.

Here the air-channels enter the airbox:

They do look small, the openings, don't they? I think they are a little bit on the small side. But this is how I'm gonna try it. There wasn't much room left for bigger air-channels, so this is wat I had to use.

edit 06-04-2006: At the aussieveedubbers.com forum somebody asked me if I planned to place scoops in the airbox to spread the air inside the airbox and cover a larger section of the radiator. That got me thinking... I thought that the radiator would create enough of a restriction so that the airbox would be pressurized. But then I tested this by blowing air through the radiator with my air-compressor. It went right through without much restriction.... Because of that I decided that I indeed needed scoops at the air-outlet. I didn't want to make it too complex, I created one scoop per air-outlet:

The air is coming in at an angle, so the scoops only have to scoop the air to the front of the car. That way the top half of the radiator will get some air-flow too... I hope...

This is the underside of the air-channel (top of the picture). As you can see, my rear swaybar is kind of in the way of the airflow. I want to catch the air that goes over the swaybar. I want to make an airscoop the width of the opening created by the swaybar. Than the width must be reduced to the size of the air-channel. I hope I will compress the air a little bit this way.

edit 20-04-2006: I finished one of the two air-scoops. It took quite some hours. I first made templates out or cardboard and then cut the different pieces out of alumium.

From the front:

I am gonna seal the seams on the inside with sealant.

Still a lot of ground-clearance, it is a bit lower than the rear sway-bar, and still higher than the lowest point of the lower shock absorber mounting:

It was difficult to fabricate because I don't have much room under the car, and the air-channel is at an angle, so where the scoop is connected to the channel was difficult to make.

Now I have to fabricate another one for the right side....

edit 22-04-2006: I finished the other one too, this is how they look when they're not installed in the car:

edit 20-05-2007: I removed the floor of the air-box and removed the air-channels because the cooling system wasn't working, see: Debugging the Cooling System
