2015 50th Anny Rush 800, Studded, Clutched (custom weights and Tied Secondary) and geared to 1.73. I am around 250 geared up. Sled had more top end prior to, but these changes resulted in a trail weapon that keeps a smile a mile on my face. Search these forums... there's a lot of info on here. You can buy a kit or you can build yours from scratch. I can tell you there are so many variables though that performance is relative to what you want to spend, the time you want to spend on it and knowing what your end result sort of looks like.
