If your purpose is to race on flat tracks and you have an engine like stage 1 predator or the Tillotson 212, that produces a high amount of power, then go for a racing clutch like a Norman GE Ultimate. More power will get you farther in a longer duration whereas more torque will help you accelerate better, therefore a clutch will be faster and the torque converter will give a better take-off. The biggest advantage the clutch has on torque converters is the power transmission efficiency is high due to chain transmission and is therefore much better for racing purposes. Most problems in the clutch are due to an incorrect gear ratio. The correct ratio depends on your tire and the weight on the kart, as a general rule, a 6:1 gear ratio for 13″ tires is ideal, if you are planning on the bigger tire or want a better take off then lower the ratio. You can set the gear ratio beforehand, and it is important to set it correctly otherwise you’ll burn your clutch real quick. When the engine starts to rotate, the shoes will experience a centrifugal force and engage with the drum, the drum has a sprocket that connects with the axle sprocket. Centrifugal Clutch:Ĭentrifugal clutches have a very basic design, they have one drum and a clutch. If you want to understand the internal workings of the torque converter then read this article. Not only will that limit your speed, but the belts end up wearing over time due to the heat produced, so you’ll have to keep changing the belts from time to time.

One major downside of using a torque converter is power loss, this is common in all belt drive systems, you’ll end up losing 20% power due to belt slippage, the power loss is even more for the 30 series CVT due to its belt being asymmetric. Making it ideal for any off-road purpose, where you need higher torque to start off. So, as your engine rpm is increasing, the gear ratio will also increase therefore known as automatic transmission.

When you start opening the throttle and the rpm of the engine increases, the diameter of the belt in contact with the driver pulley will start to increase and consequently, the diameter of the belt in driven will decrease. When the engine is idling, the belt in contact with the driven pulley has a much higher diameter than the belt in contact with the driver pulley.
The driver pulley is in contact with the engine crankshaft and the driven pulley is in contact with a jackshaft, the jackshaft has a sprocket along with the pulley, and that sprocket is connected to the axle sprocket with a chain. Apart from the pulleys, there is a belt that connects the 2 pulleys. The torque converter consists of 2 pulleys, a driver pulley, and a driven pulley.
