Max Speed 37-39 mph... that's pretty fast for a go-cart.
fast as it needs to be.

Dude it is an econobox not a racecar. Stickers and a shopping cart handle don't make it fast. About as fast as a shopping cart can go downhill
about 60 to 80 mph
up to 40 mph
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.
It would depend on the gear ratio.
25 if thers to people in the go cart and if thers only one person in the g cart then it will go 30 to 40 mph
with a good sentrifical clutch about 40 to 50mph
60mph-70mph top speed
25-40
