I was running my off road lil kart on centrifugal clutch with a F-N-R transmission but I guess centrifugal clutch is not the right application for off road,.this torque converter is being doing the job much better,.I installed it upside down kinda,no space for it behind the engine because the transmission and it looks weird but after it gets on mud everything is going to look just fine,.or ugly...so far so good
