[QUOTE="David Hester, post: 6576605, member: 6794"] [B][I] It should make a small venturi effect and help make it more effective.[/I][/B] True just having some fins hanging down in the wind does not a diffuser or wing make. Otherwise there wouldn't be so many funny crashes (and short "flights") on the RedBull Flutag highlights. ;^) There is so much turbulence under our cars, a few flaps at the back can't do much. I'm a pharmacist not an engineer, but my Dad was. I'm thinking unless you can build a taper into the diffuser, narrow front, wider back and/ or a aero taper (upside down wing), you are wasting time and money. Psyche factor may have some value. You want the taper to be enough to speed up the air, but not too steep as to cause seperation and just drag (or stall). I'm afraid a flat piece of aluminum riveted to the gas tank cover and rear bumper cover isn't going to cut it. [/QUOTE]
