I just bought the new GoPro HD and it has a microphone port on it. Does anyone have any recommedations on a good microphone that I could run either to the engine or the back of the car to catch the exhaust?
Do you plan to use the GoPro inside the car or out in the open air? I mounted my GoPro on the roll cage inside my miata. I used the open back for the GoPro and you can hear the throttle pretty good. Of course the only testing so far has been at autocross speeds, but might be a good option for you.
