Right now i have the HV-Maxx on 14 cells what top speed do you think i am getting with this setup? Spur 70 14 pinion and stock tires.

Would a Warrior 9920 Brushless and a Feigao brushless motor 540 9L or 10L be a good upgrade from the HV-Maxx motor? Also what top speed do you think i could get? That setup would be the best i can get?
