Stall speed

Just like a cam, it’s application specific. You racing? Cruising? Mostly highway? Gear ratio? Weight? Call a quality converter company and give them the details, but be brutally honest with yourself on what you want.

In my small town where everything is 25mph, I run short gears, and I aim my stall speed at my 65 mph cruising rpm. Not because I do a lot of highway, but because I don’t want to create excessive heat if I decide to. Loose or tight, long term cruising under the stall speed will create more heat due to slippage.
