I don't know the specs on the Tormach, but I run a 2.2kw BLDC. They say it's almost 3hp, but I run my spindle 1:1, so while I might be HP rich I am definitely sacrificing torque. I can run that 2" face mill pretty hard, but I have overheated my motor and it goes into overheat protection. And my G0704 is such a wimp that it gives up much over like .0025" depth cuts., a .008" cut with the 2" face mill would wreck the thing. I'd find it on my neighbors lawn. I've also got to stay at like 25% step over. The joys of these small machines...
Some day I'll get a divorce, buy a large warehouse, install a 20 ton VMC and small apartment, and live happily ever after. It's the American dream!
