Torque Converter question

OK I am retarded when it comes to these things. How exactly do they work? For example how would a 2800 stall on my car benefit me? I know they drop ETs and all that but what about it helps you? I want to get one, but first I wanna know why.
Can anyone help me out here? Thanks much.

I wrote a brief intro to torque converters on the site www.kennedysdynotune.com Click on the "Tech Tips" button on the bottom of the left hand menu bar and you will find it there. That may get you started.

In the most simple terms, a torque converter will stall at a certain RPM's and help to get you immediately into your power band.

Basically the torque converter will allow the engine to rev up indepedent of the transmission until it reaches a certain RPM (stall speed) in which it will engage 1:1 with the transmission.

You should match your torque converter to the power range of your cam. If you have a 3600 stall but your cam makes power from 2000-5600rpms (for example), you don't have the most effective setup since your torque converter will automatically bring you too far into your power band.

Conversly if you have a 2400 stall and you aren't really making power until 3500, you are going to spend time below the rpms you want to be at.

Hope that explains it for you well enough....sorry, working back to back shifts and the brain isn't functioning too well but I'm sure you get the point.
