I am building a race kart and have set my goal of a 50+ HP motor. I am comfortable with with overvolting by 20% no more( less preferably). I will be running a 96V 450-500amp max 160 amp continuous system. With a P&S 144v 500 Amp controller. My current thought is the D&D es-31b http://www.evdrives.com/dd_motors_ES-31B.html
But this motor is 83lbs I was hoping for something 50-60lbs. Any ideas?
