Why does weight matter?

Let's look at this face value... many of us with some experience with these things; can tell you that you do not want to be going 55mph in a MT.

I have tried it with my 1512 Neu motor (1512/3D on 7s2p A123), it was awesome for the first few passes at speed, but after that the fun disappears and fades to being mildly boring. It is also FAR to stressful 'trying' to control the truck at these speeds... it is "guaranteed" (mark my words) that you WILL crash at some point, and severely damage the trucks equipment.

Second, if you REALLY want to do this, you only need a 1515 (you can do it with a 1512, but 1515 would run cooler, and more torque at those gear ratios).
