When I took delivery on my 2008, it was considerably faster than my brothers low hour 800 SXR (stock). I if it is well taken care of, I bet you'll be impressed with the performance in stock form, I was. Add a pipe, head, then porting; $1500 later and your golden.
In my opinion no matter what tubbies you add to a pre-08 hull youl never get the handling of a 2008+ hull. The pump was moved back in addition to the change in the hull.
