I did some tuft testing. Earlier I had asked about hood height so I figured I could collect some data for that. Tomorrow I hope to get some more tuft testing on the windshield itself. Once I get some more footage I am going to put it all together and upload a video on youtube I can link to. This was taken around 65 mph. The one that is between the hood and fender was not always like that. I think it might have gotten stuck.
Just based on this it seems altering the hood to windshield angle may not provide any benefit.
