VXL esc + 2600 ammo = ???

That gearing will give you around 30mph with the close ratio gearset. The vxl esc is not better then the MM. I have owned both and do not think the vxl esc is better. It has no pc programibility and runs warmer then the MM. It is also not as smooth either. The batteries will determine how much power you will have. The motor will draw as much as it can (till it overheats) that is why gearing correctly is important. If you can buy the mm I would suggest it over the vxl. I have 7 MM escs and have been very happy with them (pity the Mamba motors are not that good). You will have to run some sort of heatsink on the ammo motor, even a clip on heatsink will be better than nothing. A fan will help the esc, may not be necessary for the motor.
