No one will be able to answer this question probable xD.

I am building an electric Go Kart from anything I can find.
I need to know what kind of power the motor should take to move the kart and how much torque the final shaft from the motor should have?

I have a tractor that just blew up the transaxle so now I have a 15.5 hp engine that runs great and nothing to do with it. How big and fast of a go-kart could I could with that?

Engine: Zündapp Turbine refregiration(Typ:280-03 1972), 70cc (origanaly 49cc), 4-speed, electronic ignition CDI(contact ignition origanaly), Bing 21mm Carburator. Frame: 30x30x1,5mm Steel Rear Axel: Zündapp tricicle, with mechanical differential Performens: 70km/h Made in PORTUGAL!

One year of racing. #55 outlaw go kart built by Nick Walsh. Powered by a 16hp briggs twin. This kart is undergoing yet another rebuild, 1.25″ chromoly rear axle, Paul Martin billit disc brakes, and wieight distibution changes just to mention a few. Should have a new build video up in a few months.
