Now you'll easily go to the 60's mph with that setup... AND have long run times to boot! I'm not sure if you really want to take an emaxx much faster than 60 anyways. Mine kept on bouncing off curbs and got airborne easily and those stock tires start getting real tricky above 50, let alone 60.

My experience with Lipos above 2000 watts is limited though. I've gotten my lipos to about 1800 watts (I didn't want to blow up those expensive batts). I test them first using eagletree to make sure that the load isn't too high for the batts first.
