Faster motors will always draw more power. That being said typically smaller batteries are ran for faster cars now, due to wanting less punch, and the physically smaller/lower CG packs handle better for mod. The thin shorties you see in carpet mod now are around 4000mah, which is about the bare minimum needed for a run in mod. For this class, a safe bet for a pack would be a ulcg (19.5mm thick) pack for carpet or maybe a lcg (22mm) for asphalt.
