I have a lightly modded LS/v and every time I video tape the engine noise is always overpowered by the wind/exhaust and other car noises. I decided to run a microphone into the Engine Bay and this is what I came up with. Next I will take a video at the same time and mate them together. Tell me what you think

Sounds like throttle body whistle to me
