Got a question about Getrag LSD... I heard it will be louder idle? or rev higher while driving?
If you change the rear end gear then yes it will change your rpms's. SRT auto's are 3.06 stock. I'm keeping it 3.06.
Note on the pulley. The power numbers on a 6.1L engine are less. The 5.7L gains the biggest. Since the 6.1L already has a smaller pulley then the 5.7L, it will not gain as much power. So you have to consider is the cost of the pulley & install worth 5HP on a srt8?
