If you read the description the facebook page with the extrusion im trying to get the air to meet at the point where the gas canister releases a burst of CO2 so the gas has something to push againt while the other not to have any extrusions is basical to control the direction of the burst of gas from the gas canister; so it helps it to go in a straight line rather than wasting energy producing life or downforce.
don't think of it as pushing against something. A rocket in space has nothing to push against. It is simply throwing stuff out of the back to go forward.
If you can imagine standing on a raft and throwing a large rock. I like the idea of minimizing lift and reducing drag. Do a little more reading on basic airfoils. while sawtooths have been used on wings to try to increase lift prevent stalling and reduce drag that doesn't mean they work in all situations. They are generally more of a band aid when trying to push the limit on an airfoil.
play with this
watch the drag and DF numbers. dont forget to adjust it for your speeds.
I am trying to get the air to meet up where the CO2 gas canister releases its thrust to create a high pressure point to push the car forward. The other idea of the ring without any cutouts is basically to just control the gas flowing out of the canister
in a straighter line as when you see the cars go forward all the gas just goes up.
