I think I found a nice option for an inductor on the input for people who want to boost their DC voltage up. There are a bunch of 20HP cheap AC motors on Ebay. Like $200 range. That is continuous duty, so you could do more for hard accelerations. I'm not sure what the 30 second rating is on a 20HP motor though.
So, I'm hoping that someone who puts 144vDC in their car can just add one of these inductors on the front end right after the battery pack, and then use a 230VAC cheap Ebay motor. Winding it sounds pretty easy too. It's a couple big 165mm (outer diameter) toroids made of "High flux" 26u or 60u (permeability). Then, you just use around 25 wraps of very high strand super flexible welding cable to mitigate the skin effect. 15 feet worth would be enough if you could wind it perfectly. Otherwise, you may have to spring for a few extra feet. It sounds perfect for the DIY person.
