Have you made changes to your 914 body or are you thinking of it?
Here are a number of computer models comparing different body modifications to the 914 and the effects that they have on the cars aerodynamic drag. http://www.cassidy-online.com/porsche914/aerodynamic_aids |

QUOTE I think most people would agree there would be little to no effect of spoilers at 20 or 30 MPH. The only time aerodynamic aids will make an appreciable difference are at speeds much greater than autocross speeds. To make it worth your while, I would think you'd need to on a big track going between 50-150MPH or greater. The aero info is interesting and I'm not trying to be negative...you just won't make much use of aero aids on an autocross track. Use your points for suspension upgrades. |

If you read my introduction on the web page you can see why I was testing my original front spoiler at all. Also a lot of the testing was done for speeds of 75mph to 120mph to help people that run their cars on large tracks. And it is useful to know the flow path as Sean pointed out even at lower speeds. |
