Whining Sound In Bellhousing Area

[larrym1961]

I have a supercharger type whining sound coming from the bellhousing area. Transmission has new main shaft bearings in it both front and rear and I also have a new throwout bearing. But this noise also was going on before I had the Trans Main shaft bearings and throwout bearing replaced. The noise does stop though when the clutch is pressed in. Anyone have a clue what would be causing this whining sound?

How did the clutch look when you replace TB an main shaft bearnings? Did you replace the clutch or use same one. If it's the old one how old is it?

I thought about a new clutch when I had Trans out but never even looked at it because it was still working and grabbing great. Originally thought the whine was coming from a bad main shaft bearing because my trans had been ran low on fluid. Anyway it's a Ford Racing King Cobra installed in 2005 and probably has 20,000 miles or less on it.
