Functional Rear Diffuser
I have been researching around for a functional rear diffuser, Nothing for our cars. I have decided to start designing one myself.
Question 1: Since i do not have a wind tunnel in my back yard i was wondering if getting a scale model and making a mini tunnel and doing tests with that to see if it will work well is a worth while idea?
2: I know for it to work the way it is designed a spoiler is also needed. the APR starts to add downforce around 40 MPH, so i was thinking about getting that and using a diffuser to futher create a suction force under neath. has anyone used this particular spoiler first hand and noticed better handling?
3: Does anyone have a home made FUNCTIONAL rear diffuser and would help me make one of my own?
4: Should i even bother?
The reason i want one is because i plan on racing next year. I want the most out of my N/A car and use aerodynamics to my advantage. Also since i work with FRP/ CF and have lots of spare time i can possibly make a few more for those that would want one.
Thanks
