I can sum up the answer to your question in 3 words... Gearing, Gearing and Gearing.
You don't necessarily need high kv motors or high rpm to get high speed. Its all in the gearing. I broke 60mph in my buggy using a 1578kv Hacker 10XL motor and 5s. Thats only 29000 rpm for the motor.
l also did it with a Neu 1512/2.5d and 5s and a Quark 80B.
You don't need the biggest motor on the block to get high speeds. All the huge motors do IMO is suck your battery down faster. You can only get so much power to the ground with the grip generated by the tires.
Get a motor that runs a comfortable RPM on the voltage you plan to use and the rest is just a matter of gearing for the performance you want (within reaason). Many times I actually think the smaller motors feel more powerfull than the huge ones. They spin up faster and just feel more powerfull and responsive.
No need to kill a fly with a sledgehammer, and the 22xx motors are sledgehammers.
