If you had zero stall it would stall the engine, like stopping without pushing in the cluch on a stick car. Stock converters are somewhere around 1500 R.P.M.'s. The higher the stall the more R.P.M.'s need to fully engage. Say a 5200 converter. It will start grabbing before 5200 but no go to full engagement until 5200.

The RPM's will rise to a point and then either just stay there (like at 2500 rpm) or the rear brakes will be overpowered. Consider that the "Stall Speed" You don't do that for more than about 2-3 seconds as you are baking your tranny fluid FAST and can potentially harm the converter if is not built for that kind of abuse. A Higher staller (looser converter) lets the engine rise to its optimum point in the powerband (assuming a hipo engine here) for a much harder launch. But it comes a price--drivability and certainly mpg can suffer.

Conventional converters have a percentage of slippage even when fully engaged. The lock up converter still has a stall speed but it takes out the slippage when fully engaged
