With 30/60 gearing your rollout will be about 1.6 which is definitely within reason for speed runs. On 2s you're looking at around 40k rpm, but on 3s you would be looking at closer to 60k rpm which I believe is pushing the Mamba 5700 to or past its limits. I think if you need more torque it would be better to go with a lower kv motor and higher voltage. Lower kv = more turns = stronger magnetic field = higher torque at a given voltage, but of course you would be sacrificing some speed.
