It is greatly dependant on the weight of the cart, the gear ratio, and the tire sizes. on a race cart a 15 hp (if you could mount it) will do between 50 and 60 mph. I have never seen one on a yard cart (lie the one seaters you can get at tractor supply) but i would venture to say you could probably push 45-50 moh with the right gearing.
Not very fast at all because of all of the weight but the 150 pounds would almost even it out.
faster than the others
My 6hp Murray go kart goes about 20mph....your and f@#king dumb a@# you can go faster then that
about 80kph for 1hour
a 125 shifter kart can reach about 115 miles per hour and go from 0-60 in about 3 seconds
50 mph
depends on motor and traction.
A 3HP motor can reach speeds up to at least 30 mph depending on what you are using it for.
