I just read the whole thread. Top speed was discussed a few pages back so I'm a late on this. I have a DM-1 Pro and I been drag racing it last year. I'm using a neu 1515 2y on 12s with 51t spur and 25t pinion. I don't know what my top speed is but the fastest I've gotten at 132ft is 72.4mph at 2.2sec. RC cal says 88mph so I think I can get higher. The most amps I pulled was 114. I went digging around and found a video of one of the races last year: http://img532.imageshack.us/my.php?image=july5thfv4.flv . My car is the black one.
