Believe it or not but my 05 900 Fusion with a 144 x 2 series 4, holtz front end, 19-41 gears would pull 65mph peak track speed on a long climb, normally would hold 55-58mph. That sled was the most impressive sled when it came to track speed that I have ever had, until the belt would blow. I will try to find some pics.
