me and my friend are trying to build a homeade go cart. we garbage picked a 5 horsepower lawnmoer engine. how fast do you think it would go if it had a 110lb rider drive. how fast if it had a 130lb driver. and if it had a 100lb driver
and driver who weighs 102lbs
I was 150 lbs, and I drove a 5hp cart up to 41 mph, with no "performance" modifications other than removing the governor (a must!).
I was trailed by a motorcycle with a speedometer, to measure the speed.
This was a three-wheeled cart, with no brakes on pavement.
You will rarely be able to drive it at full speed, unless you live on a street without traffic. Most become unstable at high speeds, and are difficult to stop. Stopping at high speeds is a complete guessing game, with very little control over direction.
Four wheeled, one-wheel drive versions (most common home-built) are notoriously difficult to drive quickly. They steer one way when you gas it, and steer the other way when you slow down. Your arm is constantly fighting the steering wheel.
Most "lawnmower" engines do not have a shaft that points in the right direction.
If the driveshaft on your "find" is not sticking out the side of the motor, it is going to be an uphill battle.
As another post has stated, the conditions and ratio of your gears plays a significant role in your speed.
Building go carts is not cheap unless you know how to make things work.
Otherwise, you are gonna be buying a lot of stuff, like wheels, sprockets, clutches, chains, brakes, frame, etc.
When you total that up, it’s more than buying a full cart off ebay. Plus, it will probably not be very good, if you don’t know how to build things.
Lawnmower is the correct spelling. Speed depends on a number of variables. What is the ratio between the drive pulley on the engine and the pulley on the axel? Are you using a live axel?? What RPM will you get ?? What is the total weight of the driver and vehicle?? Is the surface you are driving on hard or soft??
that depends on soo many things, loss of power through the drive system and tires, gear ratios, kart and driver weight will affect it too. weight matters less than you might think for top speed it affects acceleration more. with a light kart and good design 40+ mph is possible with a stock 5hp engine provided its geared good. what engine you got?
