First maybe double check the timing on the can.. most current short stacks like timing in 48-52 degree range.. that can help with some top end.. Then work on the pinions .. For stock racing, motor and battery can become important when you've exhausted all other setup and driving variables but normally more can be found with better setup and or driving.. As for the charging bit.. higher charge rates can yield a bit better punch early in the run however in this case, it doesn't sound like that's the issue at the moment.. When you feel that your getting as much as possible out of the motor, begin looking at minor setup changes like less rear toe, less droop, and things that will free up the car a bit. Freeing up the car will help to reduce motor temps, not drain the cells quite so much and generally aid in carrying more speed throughout the track ... I hope some of this will help get you going in the right direction .. the others may chime in with more ideas as well ...
