I haev one in development and with any luck I will have some pics to show you soon
The effect is called Venturi. you might remember it from high school physics or college physics. Venturi Effect states (from wiki)The Venturi effect is an example of Bernoulli's principle, in the case of incompressible fluid flow (in our case, let's just use air flow under the car) through a tube or pipe with a constriction in it. (think the road to the underside of the diffuser) The fluid velocity must increase through the constriction to satisfy the equation of continuity, while its pressure must decrease due to conservation of energy: the gain in kinetic energy is supplied by a drop in pressure or a pressure gradient force. (read: same amount of air flows faster in a smaller channel than through a bigger channel.)
As the diffuser sweeps upward, it creates a lower pressure. think like the top side of a wing. it'll suck upward. well the diffuser is 'upside down' when its installed on the underside of our car, so this sucking motion will in a sense suck the car down toward the ground, thus theoretically giving the car higher downforce. starting the diffuser closest to the rear axle and having it gradually sweep upward to the end of the car is most beneficial. but with all the junk underneath our car, its a little bit harder, so we have to work from rear subframe back...
