Stall converter

[juergs8]

I was wondering if anyone could explain a stall converter to me and what it does?...and how it will help, is it absolutley necessary when changing the cam or is it just to get a quicker acceleration.? if so why?
Thanks for the help

If your stall speed is below where the cam makes enough power to move the car forward the car will spit and sputter or die. It allows a controlled slip to a range of rpms so the engine is making power to move the car and not bog down and die. Some like to slip all the way up to just before max power so they get that surge and launch at max power.
