I recently installed the Whipple Stage 1 kit on my S550 and was looking for advice on swapping the oil pump and crank sprocket gears. In terms of power I won't be doing anything beyond the Whipple 750hp tune they supplied with the SC kit. Does anyone have experience doing this? If I'm not going to be racing the car, how important is it to swap these out? The Whipple install took me 2 1/2 days in the garage, and I don't have any free weekends coming up, so I'm considering letting a shop do this for me. Thanks in advance.
