According to Racecar Engineering, Missouri recorded an 800% improvement in aero downforce at 40mph with front and rear wings. They recorded a 1.6g skidpad at competetion. Their windtunnel test showed aero gains as low as 20 mph. They are using triple stage wings with angles of attack in the 30-40degree range.

Was that on a 914? |

I could build all the downforce in the world into a car, but the drag and extra weight would make it a tank.
To get any appreciable downforce at 40 mph the drag from the wings would have to be huge, the benefit is outweighed by the cost. This thread was about reducing drag at an AX, big wings don't accomplish that. |

Does anyone have any info or more pics of this car? I imagine the hatch was a custom thing, but man... if there is one thing the 914 could really benifit from at high speed it would be this---- as indicated by the test results! |
