It basically works like a clutch for autos... I'm bad at explaining this...

Say you have a 2800 rpm stall converter. At idle it'll be fully unlocked. Once you hit the gas it'll allow less and less slippage up to 2800rpm, sort of like letting the clutch out to that point. After that it is fully locked up just like the clutch is fully engaged. A big plus to a higher stall converter is the ability to come off the stall under a full load/boost from a standstill.

Then you have torque multiplication... under initial acceleration most torque/stall converters have a multiplier of 2.5:1 so you can definitely understand why most serious drag cars are automatics. You come out of the hole MUCH harder not to mention the auto will never miss a shift...

At any rate, that is the basics of a stall converter... very basic...

I'm a mechanic as my primary job but not on cars, maybe that helps?

I went through all this last year when I was looking for a high stall torque converter and I was told buy the techs at summit racing when your looking for a T/C you want to go 300 to 500 RPM's higher in the stall then what your baseline power for your Cam is: example my cam's baseline is 2,200 RPMs and I went with a 2800-3000 stall torque converter !
