Converter Tq Ratio
The higher the tq ratio of a converter the better for say drag racing. The tq will multiply until the tires break great for that hookup then drop off quickly.......
Custom converters can be built to fine tune the tq X, and stall speed but can run into $3,000+ cost w/kevlar clutch, or multi clutch setup.
Consider tq output of a diesel and things can go bad quickly if the tranny can't take the tq multiplication load.
For a given stall speed od say 2,000 rpm's the actual stall would be in relation to the engine tq output, higher than stock then the stall rpm's will increase, engine tq output below stock and the converter will stall sooner.
