22hp torque converter

[ROLY239]

deciding on purchasing a Lifan 22hp engine but i dont know any torque converter that can withstand 22hp. A few people have recommended the 40 series but I feel like it wont be able to handle that much power. Thanks in advance

I'm hoping for more than 22HP out of my 420cc engine and plan on using a knockoff 40 series.

Call Geoff at Vegascarts.com

I'm sure he'll have a good recommendation for you.

Or the 94c duster clutch.

Is it a 1" crankshaft?

Yes it’s a 1inch crankshaft. What driven would I use with the 94c duster?

I guess the 90D driven unit that is listed below it in the link. The 90D has just under a 10" Diameter and comes in either a 3/4" or 1" bore. So you need a 3/4" or 1" jackshaft. It takes a 1-3/16" belt.
