Thus situated, and even though the movable faces shift back and forth each counter to the direction of the other, it happens that the belt is carried in virtually constant alignment to the stationary faces, since the belt is at all times forced by the movable faces against parallel and nearly vertical stationary faces (just 2-1/2 degrees in angle) which are "inboard" of the belt and mounted directly in line with each other. If you make its clutch engage when your engine is producing the most torque, you acquire a good take-off and can also do wheelies. It depends on the engine design, but most of them are compatible with go-kart engines from brands such as: For a standard TAV2 equivalent torque converter that is compatible with a 30 Series belt, the gear ratio usually starts around 2.7 : 1. The best go-kart torque converters in this list come with a compatible belt (30 or 40 Series). If not, where should i be looking? Here Is How To Make Ninebot Go Kart Faster (Easy Steps).

Can a torque converter be use with a 500 cc engine (or larger)? The stationary sheave is the pulley face that remains in place as the moveable sheave changes postion to create various pitch diameters. Its combination compression/torsion spring together with the mechanical advantage of its "cams" give it ability to both respond to and also to over-ride the centrifugally-controlled driver member and therby achieve (shift to) a torque multiplication ratio that, at any given moment, is a balance between the engine's power and the torque requirements of changing vehicle load and/or terrain. The major difference is the type of weight-spring system they both use, the weight-spring system is inside of the driver clutch (the driver clutch is the part that goes into the crankshaft), which experiences the centrifugal force as the clutch rotates with the crankshaft.
