First,
it does do something...
Second
I'm not sure it helps the contour. I had some driveability issues with the setup. When coasting above 20 MPH with no load the engine would stall.
I did have better throttle response at highway speeds and my fuel milage did go down. So I assume it did something.
To test I placed the car in my driveway, started it and let it idle a while (when it was at normal running temps) I then took a leaf blower and directed air at the scoop. It leaned out the engine and it stalled. This was repeated several times.
I removed my homemade scoop and attached my 3" tube to the sub frame and used it as cool air induction.
BTW I really just cut a 3" hole in the bottom of a stock SE air box, put a K&N drop in in the box, closed it up. Ran some flextube to the front bumper. I rigged up a temp scoop from a large kitty litter plastic bottle for testing and drove it around for 2 weeks.
No water problems as the air had to travel up amost 90 degrees to the road. If you can rectify the driveablity issues you may pick up a spare pony or two.. but only at highway speeds. I figure you will be lucky to get 1 PSI postive pressure total from under triple digit speeds.
