I am hearing an abnormally loud humming noise coming from near the alternator. After the humming sometimes there is a click. I have had 2 s2000s, with over 180,000 miles combined so I know its not normal. It almost sounds like a loud fuel pump, almost like the ac unit/radiator fan turning on but a lot louder and more of a humming sound. Could it be a bad alternator?

Thanks in advance.

happens to me too. when i try to give it a lil bit extra gas it has that buzz/humm sound but goes away after rpm hits high and exhaust takes over.

do you have any issues with idleing or is it just loud?

anyone?

is it possibly the tone that some hear from the intake (comes from past the throttle body i believe, and out the intake). mine definitly does this, and is quite noticable.

i know you said you've had S's for a while and u know its not normal, but from what ive ready its only pressent on some S2000s, not all of them.

no problem with idleing or i should say nothing really noticeable if there were problem i wasn't aware of it either

you might have a supercharger

will the bent pully damage the engine?
