2200 KV is the unloaded spin rate per volt. Some motors have different wattage ratings. If a motor has a higher wattage rating - you can "gear it up" and go faster. Speed is effectively horsepower delivered to the road. Wattage is a unit of work - same as horsepower. So, higher wattage - able to drive a higher gear = faster.
A 2200KV motor that is rated 1000W and a 1100W motor - the 1100W (watts) will be more powerful. Those are usually the longer motors (ie. Medusa 3680 vs. a 3670 - 80mm is longer than 70mm).
To deliver that wattage, you need volts x amps. You must be able to deliver the motor's wattage rating based on batteries hooked up. If you use a 4S lipo, that is 14.8 volts. 1100W motor. Divide 1100 / 14.8v = 74Amps. If you have a 4S1P 14.8v 5000mAh battery rated at 20C continuous, that can deliver up to 100 Amps. That would work. But if your motor is rated 1800Watts - that needs 121 Amps (or a higher Cell-count battery like 6S1P).
