It's hard to tell, but I would guess it's at engine speed. As I mentioned, it's most prominent during acceleration on the road, if you rev the engine while stationary you don't hear it, so it has to be under a load I guess. Lately I notice that the engine is running rough at very high revs ( gas to the floor in second gear for example). I'm going to run a compression check on it tomorrow and I'm also replacing the fuel pump this weekend to see if that helps but I'm not too hopeful since the roughness doesn't go away when I engage the electric fuel pump. The car has really run flawlessly for the past year, and I drive it almost on a daily basis since I retired in April. It's just in the last month or so that I've encountered the noise and now the roughness at high revs.
