what started with an occasional whine from the belts, has now progressed.
The tensioner pulley is looking loose, the belts are whining, (obviously need to replace the tensioner) but now the boost on the super charger seems to be dieing as-well.
I owned and worked on a Pontiac Grand Prix GTP, but wrecked it last yr. Recently bought this one but don't know how often anything was serviced, and if and when the oil in the supercharger was last changed. I'm missing the boost of power when I put my foot down
My question is, what do i look for in regards to power loss in the super charger ?
