Don,
I don't know which Go Pro he has but you might contact Deckofficer over on the T-Bucket forum. He has posted several videos and his are so quiet that you can hear him talking and he has an open car also. The only noise you hear is when he starts to give it more gas and the engine sound is just as clear as it can be. He has a Track-T so it is as open as the Cobras. I thought that the video quality was great also.
