How do the plastic air foils that mount under the car, infront of the engine, help cooling? Are they worth adding?

If I extrude the same profile, we could play with how they're cut, but my first thought is to make it pretty close to the same shape, they spent a bunch of effort to make these the way they did. I know that they were a molded part instead of extruded, they may have done this as it was cheaper for them in large quantity. I know there was someone that was modeling aerodynamics for the 914, I would be curious to see if this was addressed, I know there was allot of conversation about tails, and some body effects. Anyone remember who that was?
I f there is enough interest and I do make these, it would be nice to see if we could tweak it to make it even more efficient. and slits is correct the air has to move faster to get over the top creating a low pressure behind (venturi effect). |
