project diffuser... if you've made one, come on in!
And on topic: should turn out to be a great project! Just don't start adding in those ugly splitters too

Just like an airplane's wing. It takes the same amount of time for an air particle to travel from front to back on either the top or bottom of the wing. Because the top is rounded, the distance is further meaning the particle moves faster, and thus exerts a lower pressure than is found on the bottom of the wing creating lift.
Here is a depiction of what you were describing:
Although I can't find that video, here is a nice .gif to show what I'm talking about:
Aerodynamics aside I'd like to see this project come together, let us know if notice a difference one way or another.
In an effort to streamline the underbody. I am ditching the true duals as they hang way to low and going back to a y-pipe, resonator (in former passenger rear seat area), running the pipe over the passenger side axle, and dumping it right before the gas tank and before the diffuser.
Some pics showing airflow under a formula car with a diffuser.
As you can see, the air speeds up greatly (yellow/org/red) as it passes under the diffuser and exits the car.
On a side note, I picked up and dropped of my aluminum sheet today to be cut out. Will be done by Monday. I am NOT adding fins at this point in time. The diffuser is what speeds up the air, fins only prevent cross-wind from interrupting flow and look ricer-ish if not made correctly.

i've looked into doing this already and have a template sitting in my garage because I never did anything with it..hmm...
Def. But shipping to Canada would be rough... It's 3" true duals made with the Summit universal x-pipe kit, dynomax bullet mufflers, and turn downs dumped before the rear axle. Sounds great but I'd like to try something different.

I am really glad this is still going. I am excited to see the results. I have seen too many "hey, what if we did this" threads. Then the guy quits and the thread dies. Keep up the good work and keep us posted!
