I don't expect a specific answer for this, but its worth a try I guess.
Under WOT I hear a type of... Rattle noise... From the driver side of the engine bay. It sounds almost as if you had a big bag of marbles and were bouncing the bag around. It's only under full throttle that I hear it. Sounds like maybe from the head? Hard to tell from the drivers seat. I've investigated it, couldn't find any loose bolts or fittings or anything.
Now I do think I have a pulley getting ready to go out but I don't think the two noises are related. Under normal cruising condition with maybe 25% throttle I get a wobble sound. Goes away with more or less throttle.
