Not very fast, possibly about 25 mph.
Not very fast at all because of all of the weight but the 150 pounds would almost even it out.
62MPH
between 40 to 50 km
that type of engine solely depends on the person on it. With the average man on it (180ib) or bigger than you are looking at 50-80 mph 180-190=70 -80mph for every 5 pounds bigger take away 5 pounds
Some clubs and leagues that you may race in will have rules about engine size.
The engine will run to the limits of it rpm (revolutions per minute). The go-cart will travel as fast as the gearing and torque of the motor allows. Theoretically, you could get a nitrous kit for an 8hp lawn mower engine and do a one-time burst to like 50 HP and maybe 100 mph, before the engine exploded and your go-cart disintegrated. One of my sons manged to get his go-cat up to 66 miles per hour using a 12hp Tecumseh motor from an old lawn tractor. Scary, very scary, but very fast. The neighbors called the police.
The top speed of the honda engine is about 35- 40 mph mongolos
anywhere from 35 mph to 110 depending on the gear ratio and the horsepower and the max rpm of the engine
A 115CC engine is fast for a go-kart. It should enable the driver to get some good speed. You can also use a 110CC engine.
It all depends on gearing, drag, engine power, but 45mph should be easy
The speed of a 7 hp go-kart engine can vary based on several factors, including the weight of the go-kart, the gearing ratio, and the type of terrain. Generally, a 7 hp engine can propel a go-kart to speeds between 30 to 50 mph (48 to 80 km/h) under optimal conditions. To get a more accurate estimate, the specific gearing and weight of the go-kart would need to be considered.
i have a 12HP ENGINE ON MY OFFROAD GOCART AND IT WEIGHS 130LBS ALLTOGETHER....IT RUNS AT 60KMH AT FULL SPEED.
