You will want a few 3500-5000mah 2s Lipos for the most fun, depending on how much runtime you want and how much room you have to fit the battery.
I would expect 30MPH when geared 8:1 overall, you could gear for more speed but you will have to watch your motor temperature. As long as you keep it under 175-180*F (appx.80-83*C), you can keep adding more gear to gain speed. Also adjust your start power and timing as needed to increase power, or to lower temps and raise efficiency.

HELPS~
8:1 will be very fast (40+MPH/63+KPH) but should be reasonable for the motor to handle without overheating, ideally I would want to start about 8.5:1 with a 6000Kv motor. Check your ESC capabilities to ensure it can handle the more powerful motor. Then get ready to crash!
