The problem with high-power is that you have to go high voltage, which is high risk for a hobbyist. I couldn't find any info on the motor in the article, but most existing EV conversion kits operate around 120 - 140 V. 110 HP is 82 kW, which means you're drawing around 600 A. Anything significantly higher than that gets really unpractical: you need huge wires (at least 00, maybe even 0000), huge fuse, huge contactor, and you're losing a lot of energy to heat.
