I just installed the Shad SH46 and Shad rack (thanks to crazybiker and bcityroller for their detailed writeups, it went pretty smooth for me), and on my first ride after install the wind noise was really bad. I've been fighting wind noise for a while, some sort of interplay between my Shoei X-11 helmet with lots of venting channels and tall CalSci windshield. But I thought I sort of had it under control until I my first commute since installing the SH46. Wind noise was back to the level that there was no doubt it was damaging my hearing. Two days later my ear still feels a little weird.
It's hard to imagine that the topcase would be having an affect on the wind noise, which is (as I understand it) mainly a question of if there is turbulence on your helmet or if the air is laminar. Maybe it's acting like the spoiler on the back of a car and creating some sort of pocket of turbulence that is reaching up to my helmet. I'm not aeronautical engineer, but that just doesn't seem likely.
I haven't had a chance to ride without the SH46 since that incident, so I haven't been able to experiment much with it. Anyone else noticed anything like this?
