So I've have some good luck with my Razor Dune Buggy adult conversion. The Chinese 48v brushless setup has been tested at up to ~68v and the controller was modified to push ~50 amps. It currently propels the 300lbs of kart and rider to 30mph while still having good torque for getting up hills.
I'd like to build another kart that has two of these motors for dual single wheel drive partly because I drive on pavement a lot and want to turn better and because I want a higher top speed. My batteries can handle well over 100 amps so the capacity is there. This would take me from ~3400w to ~6800w. I need help with determining what the new gear ratio should be so that acceleration remains the same. With that info, I can then figure out the the new potential top speed.
I've seen various formulas online, but all of them make what I'm doing seem impossible with the power I have.
