Default Roof Rack wind noise

We're in the process of adding a roof rack to our 4x4 rig. we are looking at something like the "Roambuilt safari rack" with the drop down tubing for an led light bar. One main concern I have is wind noise while on the road caused by the front of the rack. Anyone out there with direct experience with this. I currently have solar panels in the front and have added a wind deflector for that.

Default Re: Roof Rack wind noise

I have a custom Aluminess roof rack with a front leaning light mount with a KC HiLights Pro6 seven light mounted to it, along with side mounted lights (two each side) and full case awning mounted on the passenger side, plus flush mounted solar panel and two antennas mounted mid rack. I do not hear any wind noise from it. I do get a little bit of wind movement from strong side winds, and it did decrease fuel economy some when installed, but no noticeable wind noise, windows up or down. Pictures included.

Install the rack. Check for wind noise. Go from there?

Feel like it's a toss up. I've had 5-6 different rack iterations on my van at this point, some have been affected by wind noise and others aren't. There's no way to really know until it's up there and you're on the highway.

Course, someone with way more knowledge than myself on aerodynamics and who works at a wind tunnel is about to post some 10 page formula on vehicular wind turbulence noise constants...
