screaming banshee under the hood
So I took the bus out for a quick little joyride, and I thought I heard a funny noise (my hearing is pretty much shot), but pretty quick it turned into a banshee screaming like a distressed ape, and then, just as quick it faded and went away. I was only about 15 minutes getting back to the barn, with no more noise. It struck me that the turbocharger is the only thing turning fast enough to make that high pitch scream. Can a turbo scream like that for about 90 seconds, then quiet down again?
