We all know the benefits of electric motors and how they deliver their power. Electric motors can put out their max torque at zero RPM, while gas engines' ratings are their max at a specific RPM, yada, yada, yada. But I've heard the saying that 1 electric horsepower is *rougly* equivalent to anywhere from 2 to 5 gas horsepower because of how they deliver their power. I'm curious if that's really true.
I am currently building a 440cc Duromax powered off road go kart/buggy that is producing around 20 horsepower and 30 ft-lbs of torque. I plan on eventually converting it to electric, but I want to have at least identical (ideally better) performance than this 20 horsepower engine. The system I have planned is a 72V, 200A max setup. This translates to 14.4KW, or about 19.3HP. That's only about a 3.5% less power than the gas engine if my math adds up, but would it technically outperform the gas engine because of the electric motor's power delivery?
My guess is that it would not just because of the power delivery but also due to less drivetrain loss (no CVT belt slip to account for). What do you think?
