Not that spring is here, I have started leaving my windows down, and I have been reminded of a sound under WOT with my '91 that I had forgotten about since last fall.
It's a very high pitched squeal under WOT, or near WOT, starting from about 3k rpms until about 5-6k rpms (could be higher but the engine drowns it out after that...). Imagine a fast-spinning metal disk being applied with light pressure to a metal plate and that's what it sounds like. It doesn't mean that what it is, though...
It only happens under load (i.e. can't replicate it just pulling the throttle cable in neutral, etc...) and it doesn't seem to be affecting power. It's been going on since I bought the car late last summer.
Where do I start to troubleshoot this? Any ideas? TIA!!
