go with 2 cells it will be more controlable, even with 45mph you will be beating him (even though trxxas says 45 it is more like 40mph revo) so if you can get your car to 45 you should still beat him and with the 2 cell i might kick it up to 50 or 55 and 10-25 mph more is smoking him plus 2 cells would be more controlable (but i am not exactly accurate to the single mile per hour i can give you a just estimate). my vote is two cells maby 600mah becasue it is lighter and 8000 mah is like 45 minutes runtime so 6000mah would be like 37-40 min which is plenty and it saves weight and it is cheaper.
