[DeTomaso] aero test-Front pillar

[Matt]

The idea was hinted by Jack to see what the front pillar raingutters removal would have on airflow. I simulated this by filling in the area as smooth and flush as I could,making a video then removing the filler and making another run. The problem was yarn is just too flimsy and whips around too fast to document and confirm any possible flow change. A better test material would help answer the question,I just haven't found it yet.
The oil or special formula thing sounds too messy and I don't have a pit crew to clean it all up! Otherwise you're right it would likely work well under the right test track conditions,just like real racers surely do.

  Did you try just squirting some 90w gear oil on the leading edge to see where it ends up?  Michael Shortt

    Jack and others,
    I did the aero test on the front pillar that you were interested in. I did not even bother to post the video as I could not get an accurate result using the yarn method.
    I honestly could see no difference with or without the filler in the pillar. I'm working on finding another material in place of yarn that does not whip around so much for my testing. If you want to see the video let me know and I will upload it but it will show you nothing profound IMHO.
    Science marches on....!
